From Intel(R) 64 and IA-32 Architectures Software Developer's Manual, one lock
or semaphore is suggested to be present within a cache line. If the processors
are based on Intel NetBurst microarchitecture, two cache lines are suggested.
This could minimize the bus traffic required to service locks.

Current AcquireSpinLock() will check if timeout happens when PcdSpinLockTimeout
is not zero, even though the spin lock is already released. It may do
unnecessary operation to read timer's counter. This update is trying to acquire
spin lock firstly. If it could be acquired successfully, needn't to check
timeout at all.

As the SMBIOS table types belong to the SMBIOS standard, they were
moved from the SMBIOS Protocol header into the SMBIOS
IndustryStandard header without the EFI_-prefix. Defines with the
EFI_-prefix have been kept in the Protocol header for
backwards-compatibility, resolving to the IndustryStandard defines.
The same has been done with the C types.
The SMBIOS table header structure had been duplicated -
SMBIOS_STRUCTURE in the IndustryStandard header and
EFI_SMBIOS_TABLE_HEADER in the Protocol file - and thus the
Protocol type was replaced with a typedef to the InudstryStandard's.
This doesn't only make it easier to maintain, but it also prevents
potential future issues as the Protocol type has been aligned, while
the standard and the IndustryStandard header declare it as
byte-packed.
This has worked well till now only because the members of the
structure do not require alignment yet.

The InternalEmptyFunction() is currently only used by code in
"UefiNotTiano.c" -- "Library functions that abstract areas of conflict
between framework and UEFI 2.0.". In the next patches,
InternalEmptyFunction() will be used from "UefiLib.c" as well, hence
promote it to "general utility" status: move the function definition to
"UefiLib.c", and place the function declaration (which is already extern)
into "UefiLibInternal.h".

The logic for interpreting the DAIF read data using the csel instruction
was also incorrect and is fixed.
