monitor/misc.h has static add_completion_option(). It's useful
elsewhere in the monitor. Since it's not monitor-specific, move it to
util/readline.c renamed to readline_add_completion_of(), and put it to
use.

When the 'cmdline' is the last entry in 'rs->history' array, there is
no need to put this entry to the end of the array, partly because it is
the last entry, and partly because the next operition will lead to array
index out of bounds.

Since commit e5dc1a6c6c43, QEMU aborts on exit if completion was used
in the monitor:
*** Error in `obj/ppc64-softmmu/qemu-system-ppc64': double free or
corruption (fasttop): 0x00000100331069d0 ***

/home/greg/Work/qemu/qemu-spapr/monitor.c:586
/home/greg/Work/qemu/qemu-spapr/monitor.c:4125
argv=<optimized out>, envp=<optimized out>) at
/home/greg/Work/qemu/qemu-spapr/vl.c:4795
Completion strings are not persistent accross completions (why would
they?). They are allocated under readline_completion(), which already
takes care of freeing them before returning.
Maybe all completion related bits should be moved out of ReadLineState
to a dedicated structure ?
In the meantime, let's drop the offending lines from readline_free()
to fix the crash.

(while at it, use g_new0(ReadLineState), it's a bit easier to read)

Move declarations out of qemu-common.h for functions declared in
utils/ files: e.g. include/qemu/path.h for utils/path.c.
Move inline functions out of qemu-common.h and into new files (e.g.
include/qemu/bcd.h)

Now that the monitor and readline are decoupled, readline.h no longer
belongs in include/monitor/. Put the header into include/qemu/.
Move the source file into util/ so it can be linked as part of
libqemuutil.a.
