Subject: hw: move fifo.[ch] to libqemuutil

fifo.c is generic code that can be easily unit tested.  So it
belongs in libqemuutil.

Subject: 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
some files to have some new explicitly includes.
