First, this commit moves the create-blocks-from-fd function over to
libsquashfs and ports it to work on an sqfs_file_t instead.
Second, the function in the data_writer that reads from a file descriptor
is adjusted to use an sqfs_file_t instead.
Finally, the tools that use it have to be adjusted accordingly.

As a side effect, this requires the data writer to keep track of
statistics.

Much simpler to just set the correct size in the end, before writing
the super block.

This should make it easier to use libsquashfs with custom setups that
embedd a squashfs image inside something else. Also, it should make
it easier to port to non unix-like platforms.

Add sqfs_* prefix to compressor, move implementation prefix up front.

It only has one user and is quite specialized actually.

The idea is to make libsquashfs.a independend of libfstree.a, so it becomes
a general purpose squashfs manipulation library. All the high level glue code
for libfstree.a and utilites that are overly specific with to tools are moved
to a seperate librarby.
This commit makes the first step by moving the stuff with dependencies on
libfstree to a seperate library.
