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.

Change all references to "__INTEL__" to "__i386__".

They are functionally identical, but the former is a BeOS/Haiku-specfic
macro that we include in the compiler specs, and the latter is defined
by GCC.

pci: change offset type to uint16 in config space API.

* The config space is larger than 255, we need to use an uint16 to access
offsets superior or equal to 256. The current API only proposes an uint8 for this.
This change switches the offset parameter to the uint16 type. Axel hinted that
the used values are the same with such a change (the doc says sign extended to 2 or
4 bytes).
I checked with GCC2 and it's indeed the case when inspecting the memory.
With GCC4, instructions are the same on function call.
* prints info about extended capabilities.
* struct pci_module_info and struct pci_device_module_info are extended with
pci_find_extended_capability().

Ported PCI module to x86_64.

Uses the x86 architecture code, made fixes to printf formats and a
couple of 64-bit fixes. Only potentially intrusive change is that I've
changed PCI.h to use uint32 rather than ulong. I don't see any way
this would cause any issues, though.

Add a way to store a new interrupt_line value to the PCI module. It both updates
the cached pci_info and writes the new value into PCI config space. Drivers
using either mechanism to enumerate devices will therefore get the updated
value.

* Add the framework for adding an arch specific module to the PCI bus_manager.
* Implement such a module for x86 which currently exports only an MSI API.
* Implement the PCI part for configuring and enabling MSIs.
* Some automatic whitespace cleanup.
