This this commit, the code that is compiled and linked to produce
libsquashfs.so (and *only* libsquashfs.so) is released under the
terms and conditions of the GNU Lesser General Public license,
allowing 3rd party programs to dynamically link against it and still
being able to release their programs under a license of their choosing.
The libutil library is also relicensed, because it is statically linked
into libsquashfs.so. This does not affect the command line programs that
remain under the GPLv3.
At the current time, the two libraries do not contain any 3rd party
contributions and thus do not require anybodys consent other than mine
to change the licensing terms (unlike e.g. libfstree.a).
The libfstree.a and libsqfshelper.a utility libraries will also remain
under the GPLv3 license.
Going forward, some parts of libsqfshelper.a will be moved to
libsquashfs.so. The parts absorbed by libsquashfs.so will then also have
their licensing conditions changed *at that time*.
For the public headers, this commit adds the full boiler-plate comment
about the license, for the source files and internal headers, only the
SPDX identifier is changed.

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.

This in turn allows for removing most of the header inclusions
within the public headers.

This commit adds a "predef.h" header to libsquashfs that exposes two
macros, SQFS_API and SQFS_INTERNAL that are used to explicilty set
the visibiliy of stuff that ends up in libsquashfs to default or
hidden.
For compatibillity with Windows which may at some point eventually be
considered, the SQFS_API define is set to dllexport IF the cpp symbol
SQFS_BUILDING_DLL is defined and set to import otherwise.

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

As an opaque struct it has a chance to change its layout in the future
without breaking ABI compatibiliy.

Requires that config.h be included before other headers, since the macro
_FILE_OFFSET_BITS changes the definitions of things like 'struct stat'.
I chose to simply include it at the top of every C file and at
immediately after the double-inclusion guards of every header.
