Cleanup: libcommon: try to split up some of the larger files

The sqsf_writer is moved to a separate header, as well as the compressor
related stuff. The statistics function is moved into the writer code, as
this is the only place that actually uses it. The writer code itself is
split up into a hand full of file in their own subdirectory.
