* using GCC 3.3 with the 10.3.9 SDK is definitelly no good idea. x264 and libtwolame remain broken for future d. releases

Patch by Mikko Hirvonen <masse at astro dot helsinki dot fi> for Firefox-1.5.x development tools detection in configure.ac. The patch is applied with some modifications of me

* added out-of-the-box support for future darwin releases. right now, the following libraries are broken (due to linking issues): cdio, cddb, vcdimager and twolame. additionally, x264 doesn't compile because of a bug in makefile/config.mak.

Some testing might be needed 

I tried on samples:

 http://www.movie-update.com/download/11372/sm3_sneak_peek.mov

According to the Mplayer mailing list, there might be endianess issues (i couldn't find s24b equivalent samples ... so i couldn't test). See http://lists.mplayerhq.hu/pipermail/mplayer-dev-eng/2006-March/041206.html

* simplified the xcodebuild part, since VLC doesn't support Darwin 6 aka OSX 10.2 anymore and we therefore don't need to support pbxbuild either

* some GUI improvements, which need further work once the vout-filter-rework is completed. this commit needs compatibility checking with current IB releases, especially for the folks interested in compiling on 10.3.

the pointer. Fixes #940

doesn't work for the sample stream I tested, but I think that stream
is bad

(not particularly beautiful code, but it works)

Script to set vlc as default player on GNOME desktops. Patch by Torsten Spindler <spindler _at_ tspindler _dot_ de>

Unlock the playlist while waiting for input to finish so that input can freely use signal on the playlist whatever the context is (Closes:#937)

* Possible (not probable) fix for 934. Can't fix as building vlc on win32 is almost impossible

* For the time being, hide simple open. Better three clicks than confusing 
  things :)

The idea is that a given error should be reported only once to the user.
At the moment, for example, we can get:
- "no suitable access module" (printed by module_Need)
 - "unable to create access" (printed by input/access)
 - "unable to open stream" (printed by input/input)
 - ...

The facilities provided here are:
* msg_StackSet( code, message ) : "throw" a new error
* msg_StackAdd( message ) : Append a message allowing to trace the message
* msg_StackMsg() : Retrieve the message

So, in the previous example, module_Need would msg_StackSet( code, "no
suitable access module"), then input/input would add "unable to create
access" and finally, input/input can print the "unable to open stream:
unable to create access: no suitable module" message.

The three functions are context-free, you don't need a vlc_object, so
that we can add verbose error reporting everywhere.
