[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.

[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.

Patch by Jose Catena:
allmul produced wrong results when the higher 32 bits of any of the 64 bit operands are not zero. As the comment correctly said the definition of param locations must change
since esp was altered, but the definitions were not actually changed
See issue #5121 for more details.

- Switch to the new user handle manager. Added more handle types to win32k. One or two step to WND, desktop heap supported.
- Test with every application in my test suite. Needs more testing and clean up. Bleeding edge!
