* enable notdirty_write for snapshots when possible Snapshots only happens when the priority of the memory region is smaller then the snapshot_level. After a snapshot notdirty can be set. * disable notdirty_write for self modifying code When SMC access the memory region more then once the tb must be rebuild multible times. fixes #2029 * notdirty_write better hook check Check all relevant memory hooks before enabling notdirty write. This also checks if the memory hook is registered for the affected region. So it is possible to use notdirty write and have some hooks on different addresses. * notdirty_write check for addr_write in snapshot case * self modifying code clear recursive mem access when self modifying code does unaligned memory accese sometimes uc->size_recur_mem is changed but for notdirty write not changed back. This causes mem_hooks to be missed. To fix this uc->size_recur_mem is set to 0 before each cpu_exec() call.
