[PATCH v5 37/50] multi-process/mon: Refactor monitor/chardev functions out of vl.c

[Jagannathan Raman <jag.raman@oracle.com>]

Some of the initialization helper functions w.r.t monitor & chardev
in vl.c are also used by the remote process. Therefore, these functions
are refactored into shared files that both QEMU & remote process
could use.
