[PATCH RESEND v6 04/36] multi-process: Refactor chardev functions out of vl.c

[elena . ufimtseva]

From: Elena Ufimtseva <elena.ufimts...@oracle.com>

Some of the initialization helper functions w.r.t 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.
