d665d696c5 hmp: added io apic dump state
Added the hmp command to query io apic state, may be usefull after guest
crashes to understand IRQ routing in guest.

Implementation is only for kvm here. The dump will look like
(qemu) info ioapic
ioapic id=0x00 sel=0x26 (redir[11])
pin 0  0x0000000000010000 dest=0 vec=0   active-hi edge  masked fixed  physical
pin 1  0x0000000000000031 dest=0 vec=49  active-hi edge         fixed  physical
...
pin 23 0x0000000000010000 dest=0 vec=0   active-hi edge  masked fixed  physical
IRR        (none)
Remote IRR (none)

caf15319e8 monitor: make monitor_fprintf and mon_get_cpu externally visible
monitor_fprintf and mon_get_cpu will be used in the target-specific monitor,
so it is advisable to make it external.

bf95728400 monitor: remove target-specific code from monitor.c
Move target-specific code out of /monitor.c to /target-*/monitor.c,
this will avoid code cluttering and using random ifdeffery.  The solution
is quite simple, but solves the issue of the separation of target-specific
code from monitor.
