This patch adds icount event to the replay subsystem. This event corresponds
to execution of several instructions and used to synchronize input events
in the replay phase.

In icount mode cpu_exec_nocache function is used to execute part of the

Sometimes io_read function needs to recompile current TB and restart TB
lookup and execution. After that tb_find_fast function finds old (bigger)
TB again

The 0.95 VHDX spec defined PAYLOAD_BLOCK_UNMAPPED to be 5. The 1.00
VHDX spec redefines PAYLOAD_BLOCK_UNMAPPED to be 3 instead.
The original value of 5 is now an undefined state in the spec, but it
should be safe to treat it the same and return zeros for data read.
This way, we can maintain compa
The VHDX spec specifies that the default new block state is
PAYLOAD_BLOCK_NOT_PRESENT for a dynamic VHDX image, and

However, in order to create space-efficient VHDX images with qemu-img

Will check it , i had been made my personal build modding the Makefile with
altivec commands in CPPFLAGS.
i dont know if it was a placebo effect but look like everything is more faster.
