[PATCH v2 04/18] vl: extract accelerator option processing to a separate function

[Paolo Bonzini]

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