'make using-bin' will download the contrib binary and install them.

macosx: added a non-implemented skeletion (just the UI) for a VLM configuration panel with a preliminary icon set

Code simplification and TimeLabel in the FSC.

Close #2080.

Basically, somewhat of a "duh" now that we have optional_arguments on OSX.
It is highly annoying however that getopt_long behaviour differs so much
between gnu and BSD implementations, and then is even BUGGY on darwin.
'--option=value' is uniformly supported  and '--option value' is a GNU getopt thing.

imperfect world etc...

We definitely don't want to use the slow mutex or risky spin locks,
unless we have to.

The exact error message is: src/.libs/libvlccore.so: undefined reference to `__sync_fetch_and_sub_4'. According to irc discussion gcc version 4.1.2 (fc8), 4.1.3, 4.2, 4,3.2 and 4.3.2 (archlinux) fail with this error message. This patch fixes it by bumping up the minor number for gcc to 4.
