replay: notify vCPU when BH is scheduled
vCPU execution should be suspended when new BH is scheduled. This is needed to avoid guest timeouts caused by the long cycles of the execution. In replay mode execution may hang when vCPU sleeps and block event comes to the queue. This patch adds notification which wakes up vCPU or interrupts execution of guest code.

cpu-timers, icount: new modules

cpu-timers, icount: new modules
refactoring of cpus.c continues with cpu timer state extraction.
cpu-timers: responsible for the softmmu cpu timers state, including cpu clocks and ticks.
icount: counts the TCG instructions executed. As such it is specific to the TCG accelerator. Therefore, it is built only under CONFIG_TCG.
One complication is due to qtest, which uses an icount field to warp time as part of qtest (qtest_clock_warp).
In order to solve this problem, provide a separate counter for qtest.
This requires fixing assumptions scattered in the code that qtest_enabled() implies icount_enabled(), checking each specific case.
