e78dd86998 bios_emulator: Don't display error when emulator terminates
As it turns out this is a normal condition, so suppress the error.

8c6ec412b4 bios_emulator: Always print errors when opcode decode fails
This is a rare event and should not happen. When it does it is confusing to
work out why. At least we should print a message.

Adjust the emulator to always print decode errors to the console.

b3521f2e49 bios_emulator: Add an option to enable debugging
At present there are DEBUG options spread around the place. If you enable
one and not another you can end up with an emulator that does not work,
since each file can have a different view of what the registers look like.
To fix this, create a global CONFIG_X86EMU_DEBUG option that keeps
everything consistent.

ad6edca379 bios_emulator: Allow x86 to use the emulator
There is an implicit assumption that x86 machines want to use raw I/O in the
BIOS emulator, but this should be selectable. Add an CONFIG_X86EMU_RAW_IO
option to control it instead.

Also fix a few bugs which cause warnings on x86 and adjust the Makefile to
remove the assumption that only PowerPC uses the emulator.

472d546054 Consolidate bool type
'bool' is defined in random places. This patch consolidates them into a
single header file include/linux/types.h, using stdbool.h introduced in C99.

All other #define, typedef and enum are removed. They are all consistent with
true = 1, false = 0.

Replace FALSE, False with false. Replace TRUE, True with true.
Skip *.py, *.php, lib/* files.
