[PATCH 02/16] vl: extract accelerator option processing to a separate function

[Paolo Bonzini]

As a first step towards supporting multiple "-accel" options, push -icount
and -accel semantics into a new function, and use qemu_opts_foreach to
retrieve the key/value lists instead of stashing them into globals.
