pci: extend MSI interrupt vector number to 32 bits

Also increase MSI message data size to 32 bits according to PCIe spec.

Remove 0xff check for MSI interrupts because it is potentially valid
interrupt vector number. Reject 0xff only for legacy pin interrupts.

- MSI-X supports up to 2048 interrupts per device that do not fit to
`uint8`.

- Non-x86 systems may use separate interrupt vector ranges for
hard-wired interrupts and MSI interrupts so `uint8` is not enough to
represent all of them.

USB: Support physical-vector bulk requests.

Introduce a new utility method, "generic_memcpy", which takes
generic_addr_t plus indications of whether these specify virtual or
physical addresses (and potentially user addresess) and calls the
appropriate memcpy variant depending.

All bus drivers adjusted to support this at once. We don't actually
take advantage of the physical addresses in any way (yet), as USB
controllers have some pretty specific requirements that would have
to be carefully validated to use these directly.

All bus drivers tested and confirmed to still be working.

EHCI: Call PrepareKernelAccess before writing descriptor chains.

Fixes #15653.

busses/usb: Move ::AddTo to be above the class constructors.

It is called before them (and is responsible for calling them),
so having it in the middle of the file does not make a lot of sense.

Already done for XHCI. Only one functional change -- removing the
set_dprintf_enabled call. Drivers probably shouldn't spuriously
re-enable that if it was specifically disabled.

More trivial syntax and logic cleanup.

Spotted by Clang. No functional change intended.

USB: Generalize logic for debug transfers used within KDL.

Pull debug transfer methods into the base BusManager class and
implement them for UHCI and EHCI. This makes it possible to have a
single debugger command installed by the USB stack instead of HCI
specific ones.

Introduce simplistic poll mode for EHCI. If enabled a thread will run the
interrupt handler every millisecond so it can check for interrupts to handle.
While this is certainly not ideal, it allows EHCI to run (surprisingly well
even) on chipsets that experience interrupt routing issues.
It can be enabled with the safemode setting "ehci_polling on" that can either
be entered using the new advanced debug option entry in the bootloader and/or
in the kernel settings file.

We need to guarantee that when cancel returns that the callback won't be called
anymore. It could happen that the transfer was already in the process of being
finished, so wasn't in the list of pending transfers anymore. Cancel would then
return even though the callback wasn't called yet. This could lead to a callback
being called after a driver was already unloaded (even after it cleaned up the
pipes it used).

* Added a separate thread for cleaning up EHCI transfers. This makes it possible to actually always wait for the async advance interrupt without hindering execution of transfers.
This pushes performance again and fixes the bug I introduced in the last change, that we could free yet cached descriptors when a previous async advance timed out.

* Switched from the old v2 callback status codes to the new v3 codes
This means that the usb_callback_func now takes a status_t instead of a uint32 status.
Also the error codes are now different. I don't see this as a real problem in binary compatibility, as the status codes were never really documented and most drivers just assumed that a nonzero status meant an error.
Source compatibility breaks for callback functions and error defines. I fixed (hopefully) all places in the tree that are currenty included in the image and affected by the change.
* Corrected error reporting in UHCI and EHCI using the new status codes.
* Fixed a memory leak in EHCI where the async advance interrupt was not triggered in time.
* Fixed another race condition in usb_raw that could cause a crash when a device is removed while a transfer is pending.

* Fixing my previous attempt at fixing cookie handling. Device addresses cannot be used, since there may be devices with the same address across different busses. A linked list of usb_driver_cookies is maintained now that relates devices and cookies.
* Fixed endpoint halt clearing. The data toggle has to be reset when we clear a stall.
* Now using up to B_PAGE_SIZE * 4 sized buffers in EHCI. They are split automatically by the host controller. This further pushes throughput.
* Optimize memory allocator settings for the above case. Enlarging it's managed space to 1MB
* Ignore the transaction error bit in EHCI. It is only of informational character as it also idicates errors that were recovered automatically. If an unrecoverable error occures, other bits will indicate this.
* Fixed some more print formats in debug output.

Control and bulk transfers are now working nicely for EHCI. This means that I can now get pictures from my camera with USB 2.0 speed. Note though that many things still are unimplemented (isochronous transfers, split transactions, interrupt transfers, queue chaches per pipe, ...). But it's certainly a nice step forward :-).

* Implementing control and bulk (async) transfers. They don't work yet though.
* Corrected the legacy support handling in EHCI
* Fixed the bit mask for total bytes in qTDs and added the data toggle bit
* Changed the boolean low speed flags to usb_speed enum that allows for low, full and highspeed

Also wrote a memory allocator that takes over memory management from the stack. It is similar to a buddy allocator. This does on the one hand remove some ugly code from the stack and is on the other hand far more scalable than the previous free list approach. This scalability is needed for proper EHCI support where buffers can go up to a size of 5 pages. The allocator is not perfect and it's memory overhead is quite high compared to the managed memory (depends on the managed block sizes), but it's quik and works well so far.

* Don't inherit Device and Interface from pipes anymore. The device has a default pipe member now.
* Since the parent of each Object is now known, we can send control messages using the default pipe of the device from all attached elements (pipes and interfaces).
* Fixed the generic {Set|Clear}Feature() and GetStatus() calls to include the endpoint address for pipe specific requests.

* Implemented the EHCIRootHub
* Reworked UHCIRootHub to be more of a utility class and moved the actual work into the UHCI BusManager
* Implemented port reset in EHCI. Ports with low and fullspeed devices are now correctly handed over to the companion host controller.

Attachs and detachs as well as port resetting / enabling works now in EHCI. Only the actual data transfers are missing thereafter ;-)

* Added individual register operations for operational and capability registers
* Added resetting the host controller which appearantly actually works

Note that you shouldn't install the ehci module if you want uhci to work.
It disables the companion host controller drivers (uhci and ohci) because it takes port ownership and does not yet give it back for low and fullspeed devices.

Also the error codes are now different. I don't see this as a real problem in binary compatibility, as the status codes were never really documented and most drivers just assumed that a nonzero status meant an error.
Source compatibility breaks for callback functions and error defines. I fixed (hopefully) all places in the tree that are currenty included in the image and affected by the change.
* Corrected error reporting in UHCI and EHCI using the new status codes.
* Fixed a memory leak in EHCI where the async advance interrupt was not triggered in time.
* Fixed another race condition in usb_raw that could cause a crash when a device is removed while a transfer is pending.

* Fixing my previous attempt at fixing cookie handling. Device addresses cannot be used, since there may be devices with the same address across different busses. A linked list of usb_driver_cookies is maintained now that relates devices and cookies.
* Fixed endpoint halt clearing. The data toggle has to be reset when we clear a stall.
* Now using up to B_PAGE_SIZE * 4 sized buffers in EHCI. They are split automatically by the host controller. This further pushes throughput.
* Optimize memory allocator settings for the above case. Enlarging it's managed space to 1MB
* Ignore the transaction error bit in EHCI. It is only of informational character as it also idicates errors that were recovered automatically. If an unrecoverable error occures, other bits will indicate this.
* Fixed some more print formats in debug output.

* Implemented compatibility workaround for BeOS to be able to write user memory from the kernel finisher thread

This fixes crashing of the USB Mass Storage driver under R5. It is fully working there now.
I hope to be able to do this more cleanly under Haiku though.

* Implemented usable thread synchronisation for UHCI and EHCI.
* Cleaned interrupt handlers for both busses, too.
* Fixed memory leak of the queue head stray descriptors in EHCI.
* Fixed warnings about assigning NULL to the module flags field.

* Implemented transfer finishing in EHCI
* Implemented actual length calculation in EHCI
* Implemented bulk transfers in EHCI
* Implemented queue freeing in EHCI
* Added extended buffer pointers to the EHCI structs, necessary when the controller supports 64bit
* Fixed debug output and removed warnings due to wrong print format

Control and bulk transfers are now working nicely for EHCI. This means that I can now get pictures from my camera with USB 2.0 speed. Note though that many things still are unimplemented (isochronous transfers, split transactions, interrupt transfers, queue chaches per pipe, ...). But it's certainly a nice step forward :-).

* Implemented most qTD and qH functions for EHCI async transfers.
* Implementing control and bulk (async) transfers. They don't work yet though.
* Corrected the legacy support handling in EHCI
* Fixed the bit mask for total bytes in qTDs and added the data toggle bit
* Changed the boolean low speed flags to usb_speed enum that allows for low, full and highspeed

Also wrote a memory allocator that takes over memory management from the stack. It is similar to a buddy allocator. This does on the one hand remove some ugly code from the stack and is on the other hand far more scalable than the previous free list approach. This scalability is needed for proper EHCI support where buffers can go up to a size of 5 pages. The allocator is not perfect and it's memory overhead is quite high compared to the managed memory (depends on the managed block sizes), but it's quik and works well so far.

* Rewrote some stack internals (again). Everything is now created using a parent object that shares the BusManager and Stack information to reduce individual constructors.
* Don't inherit Device and Interface from pipes anymore. The device has a default pipe member now.
* Since the parent of each Object is now known, we can send control messages using the default pipe of the device from all attached elements (pipes and interfaces).
* Fixed the generic {Set|Clear}Feature() and GetStatus() calls to include the endpoint address for pipe specific requests.

* Redisigned some of the USB Stack. Unified constructors, removed redundant functions and moved some other functions around
* Implemented the EHCIRootHub
* Reworked UHCIRootHub to be more of a utility class and moved the actual work into the UHCI BusManager
* Implemented port reset in EHCI. Ports with low and fullspeed devices are now correctly handed over to the companion host controller.

Attachs and detachs as well as port resetting / enabling works now in EHCI. Only the actual data transfers are missing thereafter ;-)

* Changed EHCI register access from port to memory mapped io (which is required)
* Added individual register operations for operational and capability registers
* Added resetting the host controller which appearantly actually works

Note that you shouldn't install the ehci module if you want uhci to work.
It disables the companion host controller drivers (uhci and ohci) because it takes port ownership and does not yet give it back for low and fullspeed devices.

* Adding skeleton EHCI driver. Some parts filled from the specs and the UHCI driver.
* Corrected some errors I found while reading UHCI.
