Make inline target_memory_rw_debug() always available and change its

While in general we forbid a "continue" from the guest panicked
state, it makes sense to have an exception for that when continuing
in the debugger. Perhaps the guest entered that state due to a bug,
for example, and we want to continue no matter what.

This commit used the wrong check to prevent an assertion failure.
After this commit, you need to start a guest in the monitor, you
cannot use anymore the "c" command in the debugger. This is
undesirable. The commit's aim was to prevent a restart
after a KVM internal error or something like that; use
runstate_needs_reset() for that.

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.

chardev-frontends need to explictly check, increase and decrement the
avail_connections "property" of the chardev when they are not using a
qdev-chardev-property for the chardev.
This fixes things like:
qemu-kvm -chardev stdio,id=foo -device isa-serial,chardev=foo \
-mon chardev=foo
Working, where they should fail. Most of the changes here are due to
old hardware emulation code which is using serial_hds directly rather then
a qdev-chardev-property.
