The patch series introduces use of d->arch.emulation_flags for non-x86
platforms (patch 1) and hooks emulation_flags to 'q' keyhandler for
debugging. emulation_flags on non-x86 systems will be used in the follow
on virtual UARTs clean up series.

Also, series adds helper macros (patch 2) which are used in re-write of
emulation_flags_ok() on x86 (patch 3, depends on patch 2).

Originally, the code was part of [1], part of NS16550 emulator v3 series.
