KD System Rewrite:

Browse source 
- Totally dynamic based on the principle of Native Providers built-in the Kernel (like Screen, 
      FileLog and Serial) and a pluggable Wrapper which is optionally compiled (Bochs, GDB)
    - Nothing changed in KDBG, except for that its settings (KDSERIAL/KDNOECHO) are now stored in
      KdbDebugState instead.
    - Wrappers are currently built uncondtionally. With rbuild, I'll make them easily removable.
    - Debug Log code simplified greatly, sped up and now supports printing even the first boot messages,
      which wasn't supported before.
    - Removed most of KDBG compile-time settings, ones which are needed are in include/dbg as macros now.
    - Left in some kdbg init code and break code, but it could be made to be used as a 'wrapper' for those
      functions. I will do it later.
    - Made a hack for KdpEnterDebuggerException..it seems to be called differently and at different times
      for GDB vs KDBG and I couldn't unite them.
    - KdpServiceDispatcher now does both the documented and ros-internal debug functions and will eventually
      be called through INT2D from keyboard.sys instead of as an API.

All in all, this patch makes KD  separated from KDBG and creates a pluggable architecture for creating future wrappers that don't require changing tons of code in the future. It improves the debug
log by printing even the earliest debug messages to it and it removes many of the manual ifdef(KDBG) but making them automatic though a single macro file. It makes extra debugging functionality optional and it
allows removal of a private API from our exports.
