Ouf!

MacOSX/Framework/VLCMedia.m: Make sure we compare the media_descriptor and not the url, as we can have two perfect different media (different meta, different option), but with the same url.

MacOSX/Framework: Don't attempt to set a value of a dictionary that is being monitored by KVO on non-main thread. That's not thread-safe.

    don't use "mmap" which already exists in stdio.h as a function
    use an evil hack to get module_t structure
    permit to compile from the source tree when VLC was built in an external build tree: make BUILDDIR=../../XXX

access/http.c: Don't track redirection if there is no input. (Fix a crash with lua art work fetching and redirection btw).

alsa: add some verbose debug (enabled only if ALSA_DEBUG is defined) due to some regressions introduced by changeset [23022]

control/media_instance.c: Send EncouteredError event. Plus detach properly from callback. Plus be don't block when releasing the input thread.
