WIP: start adding interrupt handlers 

This commit should not compile and was made just to save current state.
framepars and sensor_common were converted to platform dirver, some file
headers were updated and ad-hoc updates to doxygen comments were
introduced.

* - system initialization (?)
* - compressor write (and global read) pointers
* - populating 32-byte interframe data
* - interrupts handling
* - tasklets
* - device driver that includes waiting for the next frame regardless of compression
