Implement grab/drop functions to increase/decrease reference count
and destroy the object if the count drops to 0.
Make sure that all objects that maintain internal references actually
grab that reference, duplicate it in the copy function, drop it in
the destroy handler.

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.

Modify the man pages and help texts to mention compression support, make
the help option display a list of supported compressors.
Also clarify the squashfs compressor list in the help text to state that
the list shows block compressors supported for SquashFS compression.

Initialize have_compressor to false before testing, to make
the check work.

Avoid namespace polution. Make sure all exportet symbols are prefixed
with either sqfs_ or SQFS_.

The liblzo2 library is licensed under GPLv2, so it is not possible to
distribute binaries of libsquashfs that link against liblzo2 under
LGPL.
This commit moves the LZO compressor implementation to libcommon,
where this isn't a problem, since the tools themselves are licensed
under GPLv3.
It removes the ability of libsquashfs to read or generate LZO compressed
SquashFS images, but the tools still can.

That is IMO less confusing and express what it is (i.e. what it has
become) more clearly, i.e. common code shared by the utilities.
