Also turn off debug messages to screen before setting up the CPU (To print a character to the screen on some ports the MMIO access should be executed, so it throws an exception).

This prevents ReactOS asserting when 'My computer'
is opened, while it tries to send commands to floppy drive.
Many thanks to patches author Doug Lyons.
The regression was introduced by 0.4.13-dev-1081-g
eeff926ede
patch was committed to 0.4.13rls and 0.4.14rls as well.
Today it was committed to master as well, as
the initially planned investigation for the root cause
did still not happen and we can not afford the time
to retest and workaround this over and over again.
Thank god that Oleg Dubinskiy was still around to retest
this again and confirmed it can still happen, because
unlike initially, personally I was not able to reproduce it
today anymore!
Since every release was work-arounded, we did never
expose the bug in any final release.
According to PC-9801 Bible p. 50, divisor for PIT will become unsupported in some cases after having removed the fractional part. Replace 19200 value with 9600 which is supported by both 10 MHz and 8 MHz machines.
Remove RTC switch from configure.cmd, now MSVC runtime checks are
supposed to be enabled/disabled via CMake define (-DRUNTIME_CHECKS=1)
Prepare for adding more dynamic analysis options
which implements the required functionality.
ntdll and ntoskrnl now have a wrapper for this, with SEH.
This protects the function against malformed / bad images,
whilst still being able to use the code in freeldr et al.
Idea from Thomas.

- Add missing allocation check in DetectApmBios()
- Check 'PM' signature in FindApmBios()
- Properly set machine type in hardware detection
- Set Component->Key value for hard drives
- Get rid of the unused XboxBeep()
- Cast Xbox LPC I/O ports to PUCHAR
- Improve shadow rendering with VGA font
- Include ntoskrnl.h in the proper order
- Add ARC-emulation support for NEC PC-98 series
- Add global definition for PC-98 port into CMakeLists.txt
- Add floppy verison of freeldr.ini for PC-98 CD boot
- Remove now unused i386rtl.c (and it doesn't contains RTL functions nowadays).
- Separate PC beep routines out into its own file.
- Also use delay function instead of BIOS interrupts.
- Improve as well the accuracy of KeStallExecutionProcessor() by using the same HW delay function.
This PR enables the developers to include the CJK standard fonts into ReactOS by adding them in Folder modules/optional. This feature is for test purpose only. You may not use the fonts illegally.
The embeddable font files are: mingliu.ttc, simsun.ttc, mssong.ttf, msgothic.ttc, msmincho.ttc, gulim.ttc and batang.ttc.

- Changes in device detection code:
* Properly check device signature.
* Сorrectly reset the IDE controller.
* Remove check for device type code.
- Fix CD-ROM sector read issue:
* Changed ATAPI packet opcode to be more universal (Some devices may not have READ12 support).
* Always use 2048 bytes as sector size when reading the data from a disc.
* Modify WaitForFlags() to stop polling if the error bit was set.
* Changed timeout to 31 seconds (ATA default value).
- Add more informational messages in DEBUG mode.
- Fix invalid IDE register value.
- Fix registers names.
Tested by Stanislav Motylkov and Daniel Reimer on XQEMU and on real
hardware MS Xbox revision 1.3 with Philips DVD drive.
It has also been tested manually on PC with a SONY DVD drive.

Surprisingly this also happens to "fix" random "Invalid Opcode" exceptions in XQEMU.
(But I think it's more like a coincidence... --hbelusca)
