As pointed out by Laurent

 It is not needed anymore as changing deinterlace settings does not
restart the vout anymore. It removes the last vlc_object_find() in
the vout code.

Some important things:
 * the test is deactivated by default as it needed netcat. To activate it you
just need to add check_SCRIPTS to the TESTS variable (I won't do it unless we
think that netcat is present on every hosts that run the make check?)
 * the test is really simple for the moment (that's more a POC)
 * we can write a small netcat-like tool to activate this test by default...

Fix use of ACLOCAL_AMFLAGS

also factorize a bit

use autoreconf instead of faad bootstrap script

We only need additional tools on OSX

OSX 10.5 tools are recent enough

Don't patch a file which we'll delete
Use ACLOCAL_AMFLAGS to point aclocal to m4/

You can now build your iOS libvlc with build_for_iOS.sh.
