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.

Also use the standard kernel-wide constants for IO or memory space

pci: Rework 64 bit base address register handling.

This moves the entire 64 bit handling into _GetBarInfo() and applies it
to the PCI address and size too. Previously only the RAM address was
handled for the 64 bit case.

Also fixes the 64 bit check to be done after the type determination.
Previously it would theoretically be possible for an IO BAR with the
lowest address bit set for that type (bit 3) to be mistaken to be 64 bit
and then skipping/mishandling the next BAR. Due to alignment this would
have needed to be a 4 byte IO BAR though.

This also corrects the limit for 64 bit BARs of type 1 devices. As there
are only two slots, only slot 0 can be 64 bit.

Also removes a copy&paste error that would lead to the high address of
64 bit BARs of type 1 devices to get taken from the h0 instead of h1
struct, corrupting its value.

Make the mandatory arguments to _GetBarInfo() references to make the
distinction more obvious and replace 0 with NULL in the default values.

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: added FindHTCapability() for HyperTransport capabilities.

* untested.
* as it's possible to have several HyperTransport capability blocks, the offset parameter
is used as the start pointer for the search in case it's non zero.

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().

pci: added pci_find_extended_capability().

* added PCI Extended Capabilities definitions.
* pci_find_capability() parameter offset is now optional.

pci: switched PCI::[Read|Write]Config to type uint16 for the offset.

pci: takes into account the 64bit address type

* when the 64bit address type is used, it means a BAR takes the size of two.
For the moment we just set the next base_registers to the high address
and skip to the next valid BAR. The struct is now zeroed on creation.
* the pci device information is more correct now, though it would be easier
to have BAR address and size with a 64bit types in the struct pci_info.

PCI bus manager: changed the type of domain from int to uint8.

* fixed narrowing conversion problem found by GCC 4.7.

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.
