Sync MT slots on reset and buffer overflow
At present we don't repopulate the MT slot values when a buffer overflow
occurs. This may lead to incosistent event being generate due to out of
sync Mt Slot values.
In this change we repopulate the MT slot values with EVIOCGMTSLOTS
system call after resetting the mapper. Now in case of a buffer overflow
a ongoing multitouch gesture will be cancelled and restarted.
