x.tp_buf was declared as a uint8_t array, but always used as
a char array (which needed a lot of type casts).
The patch includes these changes:
* Fix declaration of x.tp_buf and remove all type casts.
* Use offsetof() to get the offset of x.tp_buf.

This patch compute the update frequency (in Hz) for each 64x64 rects.
Any adaptive encoding can get this value using vnc_update_freq(), and
switch to a lossy encoding if the value is too high.
The frequency is pre-calculated every 500ms, based on the last 10
updates per 64x64 rect.
If a 64x64 rect was not updated in the last 2 second, then the frequency
became 0, and all the stored timestamp are reseted.
