USB: Rework the PhysicalMemoryAllocator to use MutexLocker.

No functional change, but will make some subsequent
changes easier and more fail-proof.

More trivial syntax and logic cleanup.

Spotted by Clang. No functional change intended.

drivers: remove some non-haiku support code.

Get USB functional on x86-64.

- Various changes to printf format specifiers to make them 32/64 safe.
- Adjustments to various descriptor structures since addr_t is not 32-bit
on x86-64, and consequently this breaks the physical structure that's
expected. Also adjusted padding to accomodate 32-byte boundaries when
64-bit pointers are in use.
- Adjustments to make use of phys_addr_t where needed.

Make the USB physical memory allocator more robust. Wait for space to become
available when there is none instead of spinning around. Might help with #8053
and #8058, though it's possible that leaks or interrupt issues are the cause
for these.

* Changed physical_entry::{address,size} to phys_{addr,size}_t and changed
map_physical_memory()'s physicalAddress parameter type from void* to
phys_addr_t. This breaks source compatibility, but -- as long as
phys_{addr,size}_t remain 32 bit wide -- keeps binary compatibility with
BeOS.
* Adjusted all code using the affected interfaces (Oh what fun!). Added a few
TODOs in places where the wrong types (e.g. void* for physical addresses
are used). Looks like quite a few drivers aren't 64 bit safe and others
will break with PAE.

* Add the kernel debugger extensions only for the haiku target.
* Acknowledge non-enabled interrupts in UHCI as done in EHCI as well.


git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@30063 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Added simplified possibility to schedule UHCI transfers from within KDL.
* Added debugger commands to resolve usb_ids to pipes.
* Adjusted the physical memory allocator to be usable in a slimmed down mode
when running inside the kernel debugger.
* Implemented USB keyboard support for KDL through a kernel debugger add-on.
* Added kgetc() and made use of it where previously individual methods were used
to ensure that reading characters always goes through the kernel debugger
add-ons and the other methods.

This has some preconditions to meet though:
1) The keyboard must be in the boot protocol (currently the case but needs to
be revisited once we have a full usb_hid).
2) The keyboard must be attached to a UHCI root port (i.e. not use EHCI or OHCI,
also not through hubs unless those are USB 1.1).
3) the usb_hid driver has to be opened for this to work. This means that for the
time between initializing USB and when usb_hid is opened by the input_server
there is no keyboard support.

Also note that this has no way of detecting hot-plug, meaning that you can't
re-attach your USB keyboard from the hub to the root port once in KDL.

On the bright side of things, since this is a non-destructive mechanism it is
possible to enter and leave KDL without loosing the USB state.

Tested OK in QEMU, not tested on real hardware yet, will see in a few minutes.

* Added some more debug output to the hub code
* Report and clear yet unhandled port changes in hubs
* Fixed the way devices that vanish on port reset are handled
* Added a status field to the memory allocator and check it creating it

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@19732 a95241bf-73f2-0310-859d-f6bbb57e9c96

* 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.
