Cleanup: try to split tar2sqfs.c in a reasonable way

This commit breaks tar2sqfs.c into multiple files:
 - options.c contains the command line argument processing
 - process_tarball.c contains the main tar repacking code
 - tar2sqfs.c contains what is left (the main function)
 - A header is added for gluing it all together.

No actual code is changed. The tar repacking code is slightly modified
to pass the sqfs writer and input file pointer around as argument rather
than using a global variable.
