Fix a very small resizing issue of Open Dialog : Reference: http://forum.videolan.org/viewtopic.php?f=14&t=48946

Additionnaly, add check for exception.

this should fix #1778, because with ts-files you don't allways have info about
video-tracks when input is started (and qt4 interface only called
controls->updateInput when status changed).

I didn't create new callback/signal for this one, but it could be cleaner that way.

poll() : Define HAVE_POLL on darwin. native poll() on 10.4 and 10.5 is good enough for usage in VLC. I tested both the rc interface and the SAP module on a G4 with Mac OS X 10.4

(And I claim the right to remove vlc_poll without SO version bump)

I would rather we move all the replacement functions to a dedicated
static import library (in future versions) though. It kinda sucks to
clutter libvlccore with such symbols.

Try to allocate the DShow device list and the buttons ONLY when switching to it and not all the time you open a file.

Remove the progressBar in the interface to show more clearly the bug in AVI fixing. Add debug too...
