Provide bindings for different languages

Would simplify life for a lot of different projects

Yes, moving a sensible chunk of the support libraries to a shared library with a clean API and a slightly more permissive license that allows dynamic linking sounds worthwhile. I will look into that.

I released version 0.7 today (https://sourceforge.net/p/squashfs/mailman/message/36780934/).

The new version builds a library libsquashfs that can be used by 3rd party applications to do all kinds of things with SquashFS images, also allowing low level poking in the data structures or embedding SquashFS in a custom container format (or vice versa; SquashFS easily allows adding custom extra data while still staying compatible).

TODOs from here on:

• Language bindings (IMO highest priority for now: Python)
• Example programs
