hw: move qdev-monitor.o to toplevel directory

qdev-monitor.c is the only "core qdev" file that is not used in
user-mode emulation, and it does not define anything that is used
by hardware models. Remove it from the hw/ directory and
remove hw/qdev-monitor.h from hw/qdev.h too; this requires...

net: reduce the unnecessary memory allocation of multiqueue

Edivaldo reports a problem that the array of NetClientState in NICState is too
large - MAX_QUEUE_NUM(1024) which will wastes memory even if multiqueue is not

Instead of static arrays, solving this issue by allocating the queues on demand...

glib: Add compat wrapper for g_poll on old glib

Older glib doesn't implement g_poll(). Most notably the glib version in use
on SLE11 is on 2.18 which is hit by this.

We do want to use g_poll() in the source however. So on older systems, just
wrap it with functions that do exist on older versions....

Switch the default for qemu_log logging output from "/tmp/qemu.log"

It is better to present homogeneous hardware independent of the storage
