Log:
[FREELDR]: Use WinLDR-style booting exclusively for ARM. Remove thousands of lines of old
code where we basically did the same thing.
[FREELDR]: Build WinLDR for ARM too, and implement the required portability functions to
get it working. Don't build "ros-style" loading on ARM.
[FREELDR]: Redo from scratch the entire paging setup for ARM. Instead of using 20MB of
physical RAM, we now only use 1MB that's passed on to the kernel.
[FREELDR]: Fix loads of bugs in the ARM loader code (ha-ha!).
[FREELDR]: Cleanup compiler and linker flags in the rbuild files.
[ARMLLB]: Remove all deprecated video machine routines that are not used anymore.
If all went well, the ARM port should now boot on Versatile platforms up until the ARM3
initialization code.
