Move the directory iterator test to libsquashfs, move the tree
scanning code to libcommon.

Modify gensquashfs to pack data using an istream wrapper, similar
to tar2sqfs. To implement the no-tail-pack option, we need the file
size, so we simply open a raw handle first, and query it (using
libsquashfs API) and then create the stream wrapper. For the output
side, we create a block-processor ostream wrapper and splice it.
Since gensquashfs is the only, remaining user of the pack-a-file
functon, we can then remove it from libcommon.

To the sqfs_data_reader_t is added, an sqfs_istream_t implementation
that internally reads through the data reader. The uses of the
data_reader_dump function are removed and the function is subsequently
removed from libcommon.

It is mainly a very thin wrapper on top of the block processor so far.

After trying removing many instances of `struct stat`, there is only
one user of inode_stat left, so move the function there.

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.

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.

Until now, filenames containing '/' or being equal to '..' or '.' where
not handled explicitly, because they are canonicalized later, which
will then fail.
This commit adds an explicit check to make those fail immediately with
a clear, specific error message.

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.
