Thanks for cleaning this up!

arch_init.c is a potpourri of various topics, I think we should rather
split this file up and move the parts to other (new?) files, e.g. the
sound specific parts to the audio/ directory.

I think somebody (Paolo?) also suggested a monitor/ directory already,
so monitor.c and gdbstub.c could go into that directory?

IMHO the separate accel/ directory is fine. After your patch series,
there are already quite a bunch of files in it, and if Stefan Weil is
right, we'll soon get acceleration for Windows and macOS, too, so the
separate directory is justified.
