[NTOS]: Rework the trap macros again. This time we needed some added complexity because of the need for runtime patching at boot. We got away with it nicely and basically implement a simple "if" in ASM, which gives us a deterministic set of instructions (vs the compiler). We then patch if if needed (see next bullet).
...
[NTOS]: Support systems without SYSENTER. Nothing was actually disabling the SYSEXIT mechanism recently enabled. Now IRET is always used unless a SYSENTER machine is discovered, in which case the jmp to the IRET code is patched with a jmp to SYSEXIT code.
[PERF]: Set WP0 bit in CR0 later, thus allowing the existing runtime patches (and this new one) to function without requiring MmSetPageProtect. Saves TLB flushes and page table walking/mapping on boot.
Left in some debug prints to see what buildbot reports...will remove if it survives.

[HAL]: Implement the profile and clock interrupt trap/handlers in C instead of ASM. This allows the kernel to remove the ugly hacks based on internal knowledge of how the assembly/stack of the HAL is supposed to look like. Everything is now done through a clean C interface.
...
[NTOS]: Remove said hacks and have a normal C implementation of KeUpdateSystemTime. It exits the interrupt through a soft interrupt exit.
[NTOS]: Implement 4 lines of support code needed to handle interrupts during V8086 mode, which were lacking since we weren't hitting this case yet.
Note that now the KeUpdateSystemTime interface is not "compatible" with Windows anymore. This does not matter, since the only possible caller of KeUpdateSystemTime is a very specific HAL routine that needs a very specific stack layout to actually work, so the chance of anyone calling this API is absolutely zero (no, not even some experimental driver. It's absolutely impossible).

[PERF]: What to do when your SYSEXIT code has a bug? Set KiFastSystemCallDisable to TRUE so it never gets used. Now, for the first time in 3 years and 3 months (not giving a specific revision # to protect the 'innocent'), ReactOS actually fully uses the SYSENTER/SYSEXIT instructions isntead of IRETD, since my code doesn't exhibit the bug and SYSEXIT is safe to use. This should save a good hundred cycles or more per system call.

[PERF]: After spending the better part of the last two days rewriting the HAL V8086 code (used for BIOS Display Reset) in C, it dawned upon me that it shouldn't even be used during bootup in the first place! The boot loader, running in real-mode, already sets video mode 12 when starting ReactOS. We then repeat the operation, but since we're in protected mode, we have to emulate the whole sheebang with V8086 mode. We now initialize bootvid without requesting a mode switch (which was broken up until a commit ago). This gives us a dirty palette and VGA state. We then call VidResetDisplay to clean up the palette and setup the VGA registers correctly, but we only reset the screen if a custom /BOOTLOGO command is used (which isn't supported yet). We therefore don't need to enter V8086 mode at all up until the switch to graphics mode from the video card driver. Note that Windows doesn't do this (Win7 might due to the new Boot Graphics Library), so we're actually booting faster!

[NTOS]: Implement a C/Extended ASM macro for generating trap stubs, removing the need to do this in ASM. The macro covers all possible entries, from SYSENTER to a fake sotware interrupt (needed for HAL changes later). By being somewhat in C, it makes the code cleaner to read and uses C expressions to make its decisions, making the code more maintanable as well. It also removes the need for separate assembly files.
...
[NTOS]: Modify the semantics of how a fast system call (SYSENTER) is processed in the stub, by moving more work in the C handler, such as setting up FS and getting the correct argument stack. Saves us some cycles too (and allows the trap stub macro to be more generic).

[PERF]: Make the trap entry/exit macros inlined, just as they used to be before in their pure-assembly forms. This should boost performance quite a bit by avoiding 2-3 extra calls during traps and system calls.
...
[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.

[PERF]: Replace early ZwClose system calls with ObCloseHandle(KernelMode). This avoids taking a system call for those cases and gives a slight perf boost to booting up the system.

[PERF]: Do not declare the PCR in KeGetPcr as volatile. It is only volatile as in "if there is a context switch, the PCR is different". You are in a LOT of trouble if the thread switches while your code is running in the first place, and your code is somehow running as a different thread!
...
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.
