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.
svn path=/trunk/; revision=45152
[NTOS]: Implement SYSENTER system calls in C as well.
All system calls are now handled in C. This code will be further optimized/refined soon.
svn path=/trunk/; revision=45148
[NTOS]: The ASM KiServiceExit/KiServiceExit2 are no more. All system call exit is now done through the C trap exit code.
svn path=/trunk/; revision=45144
[NTOS]: Implement C version of KiServiceExit, the second system call exit routine. This one sets a new EAX value to be returned to the caller and is used by system calls.
[NTOS]: Implement NtContinue in C instead of ASM. Due to the changes above, this can now be done in C and use the new KiServiceExit.
svn path=/trunk/; revision=45142
[NTOS]: Implement system service exit (for system calls or KiServiceExit2) in KiExitTrap. Both iret (for user calls), jmp (for kernel calls) and sysexit (for user fast calls) are implemented.
[NTOS]: Implement KiThreadStartup in C instead of ASM. It is the first caller of the new KiServiceExit2. Threads now start up in C!
svn path=/trunk/; revision=45141
[NTOS]: Implement KiComputeTimerTableIndex in C instead of ASM. Based off eVb's ARM implementation, bugfixed to do correct math instead.
As a side effect, this should fix timers on ARM ;-)

Fix buffer overrun in ExFreePoolWithTag when dealing with a PoolType other than NonPagedPool and PagedPool. Spotted by Amine Khaldi.
svn path=/trunk/; revision=45134
KiTrap0DHandler: fix buffer overrun (Spotted by Amine Khaldi) and optimize the code by checking the counter variable, instead of Instruction, this works the same, but the compiler can make sense of it and safe one comparison.
