[PATCH v7 02/31] main loop: macros to mark GS and I/O functions

[Emanuele Giuseppe Esposito <eesposit@redhat.com>]

Righ now, IO_CODE and IO_OR_GS_CODE are nop, as there isn't
really a way to check that a function is only called in I/O.
On the other side, we can use qemu_in_main_thread to check if
we are in the main loop.
