monitor: Split out monitor/qmp.c

Move QMP infrastructure from monitor/misc.c to monitor/qmp.c. This is
code that can be shared for all targets, so compile it only once.

The amount of function and particularly extern variables in
monitor_int.h is probably a bit larger than it needs to be, but this way
no non-trivial code modifications are needed. The interfaces between QMP
and the monitor core can be cleaned up later.

[monitor_is_qmp() tidied up to make checkpatch.pl happy,
superfluous #include dropped]
