This series makes the following functions thread-safe: qemu_mod_timer_ns() qemu_mod_timer() qemu_del_timer() qemu_timer_pending()
The following were already thread-safe: qemu_free_timer() qemu_new_timer() qemu_timer_expired() Now it is possible to use QEMUTimer outside the QEMU global mutex. Timer callbacks are still invoked from the main loop. If a thread wishes to run timer callbacks it must use a thread-safe QEMUBH (which Ping Fan Liu is working on). Note that host_clock is not thread-safe because it keeps state and invokes reset notifiers. Device emulation threads mostly care about vm_clock, so this is not a problem.
