qemu-tool: revert cpu_get_clock() abort(3)

Despite the fact that the qemu-tool environment has no guest running and
vm_clock therefore does not make sense, there is code that gets the
vm_clock time even in qemu-tool. Therefore, revert the abort(3) call
and just return 0 like we used to. This unbreaks qemu-img/qemu-io with...

main-loop: For tools, initialize timers as part of qemu_init_main_loop()

In some cases initializing the alarm timers can lead to non-negligable
overhead from programs that link against qemu-tool.o. At least,
setting a max-resolution WinMM alarm timer via mm_start_timer() (the...

qemu-tool: Fix mixup of int64 and int64_t

Commit cbcfa0418f0c196afa765f5c9837b9344d1adcf3 (link the main loop and
its dependencies into the tools) introduced stray usages of int64.

Use int64_t instead.

link the main loop and its dependencies into the tools

Using the main loop code from QEMU enables tools to operate fully
asynchronously. Advantages include better Windows portability (for some
definition of portability) over glib's.

core: remove qemu_service_io

qemu_service_io was mainly an alias to qemu_notify_event,
currently used only by PPC for timer hack, so call
qemu_notify_event directly.

qemu-tool: Stub out qemu-timer functions

Block drivers may use timers for flushing metadata to disk or
reconnecting to a network drive. Stub out the following functions in
qemu-tool.c:

QEMUTimer *qemu_new_timer_ns(QEMUClock *clock, int scale,
QEMUTimerCB *cb, void *opaque)...

tools: Use real async.c instead of stubs

It's wrong to call BHs directly, even in tools. The only operations that
schedule BHs are called in a loop that (indirectly) contains a call to
qemu_bh_poll anyway, so we're not losing the scheduled BHs: Tools either use...
