replay: do not build if TCG is not available
this fixes non-TCG builds broken recently by replay reverse debugging.
Stub the needed functions in stub/, splitting roughly between functions
needed only by system emulation, by system emulation and tools,
and by everyone. This includes duplicating some code in replay/, and
puts the logic for non-replay related events in the replay/ module (+
the stubs), so this should be revisited in the future.
Surprisingly, only _one_ qtest was affected by this, ide-test.c, which
resulted in a buzz as the bh events were never delivered, and the bh
never executed.
Many other subsystems _should_ have been affected.
This fixes the immediate issue, however a better way to group replay
functionality to TCG-only code could be developed in the long term.
