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. Signed-off-by:
