[NTOS]: Cleanup the traphdlr.c vs. trap_x.h mess into something much more structured. trap_x.h is now all inlined C functions which pretty much replace the asmmacros.S file. It is meant to be used outside the kernel as well (such as by the HAL, which requires trap entry/exit too).
[PERF]: Give UNREACHABLE another try, this time with GCC 4.5+, 4.4+, 4.4- and MSVC support.
[PERF]: Remove ABIOS checks since ReactOS does not support this, and since it doesn't look like the target kernel actually does either, we can remove this vestigal/unsupported code, saving some extra branches and checks.

[NTOS]: Do not attempt querying the Registry Primary Handle for the Backing Hive File Size in the case where there is no actual Primary! There was no error checking so nobody noticed this happens -- it also probably resets Cluster to 0 (instead of 1), which can cause corruption in some cases.
[NTOS]: Make KiUserTrap use the MODE_MASK instead of hard-coding a check for Ring 0 CS (which is slower and not as correct).

Need to revisit/finalize this decision and whether or not we can emulate the C-interface with Ke386EoiHelper somehow (reliably).

This change makes C code a lot neater, especially during PCR access, because it doesn't force reloading the PCR each time. For example, Read-Modify-Operations on the PCR, such as AND are 1 line of assembly instead of 3.
This helps and will help further with the C HAL, as well as the C trap handlers.

44886 KxAcquireSpinLock: check for already owned lock only on debug builds, fix check in inner loop, don't call Kii386SpinOnSpinLock inside the inner loop, but instead of it, simplify the code. Stubplement Kii386SpinOnSpinLock in C
44893 Move spinlock inline functions into their own header, so they can be shared with hal.

Cleanup part 1/x
- Rename each architectures default hal to "hal" and delete the stubbed "hal" module.
- Delete halamd64 (will later reuse the x86 hal)
- Rename "halmp" to "halmps" as it's called on windows
- Set HalInitSystem as entry point
- Move pcibus.c into hal_generic.rbuild
- Use a common .pspec file
- Use a directory.rbuild for halx86 as it was done for the other architectures already
- Move some code from hal_generic to hal_generic_up
- No code change

[HAL]: Add code to detect EISA systems with ELCR (Edge/Level Control Register). Since the current HAL does not support these, warn users about any level/shared interrupts, since they are likely to cause trouble.

New noteworthy improvements include (in addition to the other improvements made in the commits that were reverted in trunk):
- Support for sending/receiving packets > 16KB in size
- Samba-tng works
- Tracert works
- Major speed and stability improvements (especially for TCP connections)
- Use ExAllocatePoolWithTag/ExFreePoolWithTag instead of memtrack

Please, next time before you harass us with e-mails, try to read your logs. LD choses a random entrypoint if the symbol cannot be found.

[NTOS]: Implement KiIsNpxPresent and KiIsNpxErrataPresent in C. It's much clearer what these are doing now.
[NTOS]: Implement KiFlushNPXState and fix some bugs that were present in the ASM version, such as a wrong NPX state check.
[NTOS]: Implement working intrinsics for fxrstor, fxsave, fnsave and enable them for flushing. We'll update the FPU trap code to use these later.

[NTOS]: Make KiSystemStartup the real C entrypoint of the kernel, and move the "Am I being booted by FreeLDR" logic inside it -- it will then call KiRosPrepareForSystemStartup as earlier.
[NTOS]: Move the Double Fault and Boot Stack declaration in C code, with the proper alignment attribute.
[NTOS]: Although the concern that KiSystemStartup cannot be 100% C since it modifies ESP is real (Thomas' original fix of Alex's code), we don't need that much of it in assembly. Instead, write a simple trampoline (KiSwitchToBootStack) inline which switches stacks and jumps to a second-stage C function.
[NTOS]: Completely remove boot.S as it isn't needed anymore, ReactOS startup is back to being (nearly) 100% C.
