file descriptor number is not a file path

Core functions and singleton media library object

The thread can be canceled when owning a block_t, so we must push a way to clean it up.

This closes #3793 and #3779

Adds a JPEG 2000 fourcc and hooks it up to the libavcodec decoder.
Also add an alias to 'mjp2' which is used to pack JPEG 2000 in MOV
by Final Cut Pro etc.

reverts 0455f985 and 7cdb0761

This is required for those containers which mux the
AVCDecoderConfigurationRecord as private/extra data
so that the AVC packetizer works correctly.

This should close #2850

This patch exposes the adjust module to libvlc_media_player/libvlc_video
and adds a frequently requested featureset: to manipulate brightness,
contrast, gamma, saturation and hue through libvlc. The patch introduces
a new set of functions analogous to
libvlc_video_{get,set}_{marq,logo}_*, hence the use of the function set
should be self explanatory.

New Functions:

* value = libvlc_video_get_adjust_int( p_mi, option );
* libvlc_video_set_adjust_int( p_mi, option, value );
* value = libvlc_video_get_adjust_float( p_mi, option );
* libvlc_video_set_adjust_float( p_mi, option, value );

New Options:

* libvlc_adjust_Enable
* libvlc_adjust_Contrast
* libvlc_adjust_Brightness
* libvlc_adjust_Hue
* libvlc_adjust_Saturation
* libvlc_adjust_Gamma

Shows user where the current input is on icon_view with tree-mode.

Not sure if it's the best way, but this enables
to show the current item even when input is stopped.

Not sure if I remembered to do all the checks needed for errors, but
works for me ok.

Not added to makefiles, as katsomo.fi hasn't responded yet.
