Do refcounting when the subpicture is actually attached to the picture,
thus only in SubpictureRegionsLink() and SubpictureRegionsUnlink() functions

Conflicts:
	configure.ac

don't run aclocal for those (we only patch Makefile.am)

- remove stuff we don't need
- replace prefix by template (.pc/.la/-config)
- include script to replace prefix template by $PWD
- use widely available bzip2 format so xz is not needed

Use:
$ make package-win32
$ make package-win64
$ make package-osx
$ make package-whatever

Setting the translation mode is the responsibility of the program. A
library must not interfere with that. It could perhaps be added to VLC.
However it should not be required as we now force binary mode by
default in vlc_fopen() and always specify an explicit mode when calling
fopen() directly. Also it would make VLC behave differently than other
LibVLC applications, which may raise really weird bugs.

...whose code was (re)moved since then.
