aout/vout were sometimes used. It was inconsistent and in some cases
those objects could be undefined (NULL).

A scaler/chroma converter is inserted as the last filter if needed.

You need a very recent libbluray for this support

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
