This patch imports publics headers in order to use features from Xen
like XenStore, PV Block... There is only the necessary header files and
there are only a few modifications in order to facilitate future merge of
more recent header (that would be necessary to access new features).
There is little modification compared to the original files:
- Removed most of the unused part of the headers
- Use of ZeroMem() instead of memset()
- using #pragma pack(4) for IA32 compilation.
- Replace types to be more UEFI compliant using a script.
OVMF, when built for IA32 arch, uses the gcc switch -malign-double. This
change the alignment of fields in some struct compare to what is
espected by Xen and any backends. To fix the alignment, the #pragma pack(4)
directive is used around the struct that need it.
Command to run to change types:
find OvmfPkg/Include/IndustryStandard/Xen -type f -name '*.h' -exec sed
--regexp-extended --file=fix_type_in_xen_includes.sed --in-place {} \;
Avoid changing the 'long' that is not a type (with the first line).
$ cat fix_type_in_xen_includes.sed

Change in V4:
- Add a README in Xen headers directory to explain what have been done
to it. It is mostly a copy/past from the commit description with some
rewording.
- replace unsigned char by UINT8 as there is no unsigned char in UEFI
types.
Change in V3:
- Remove unused header sched.h
- moving xs_wire.h in a later patch, where it's first needed
- moving io/blkif.h in a later patch (XenPvBlkDxe: Add BlockFront client)
- moving event_channel.h in a later patch (XenBusDxe: Add Event Channel Notify)
- using #pragma pack(4) for IA32
- headers trimed down, removed most of the unused struct/define/...
