core: add new support for reading .cue files Playing a .cue file directly will now parse the .cue file, and load and play the file(s) referenced in the cue. If multiple files are referenced, a timeline including all files will be created to create the impression of a single, flat audio file containing all the tracks. For each track, a chapter is created. The chapter navigation commands can be used to jump between tracks. The chapter titles will use the string provided by the track's TITLE cue command. (The -identify command can be used to print all chapters in a not so user friendly way.) Other than the chapter names, there is no attempt at displaying or exposing any other meta data contained in the cue files yet. The handling (or lack of thereof) of gaps (track pregaps and postgaps) is probably not correct yet. In general, mplayer's mapping of tracks to the source audio files can be verified by examining the timeline, which will be printed when passing the -v switch. Note that this has nothing to do with the old cue:// support. The old code isn't touched, and is still only able to play .cue/.bin pairs. Prefixing a .cue file with cue:// will always invoke the old code, while playing a .cue file directly (i.e. "mplayer file.cue") will always use the new code. Playing audio images (.cue/.bin pairs of files) doesn't work yet.

Rename directories, move files (step 2 of 2) Finish renaming directories and moving files. Adjust all include statements to make the previous commit compile. The two commits are separate, because git is bad at tracking renames and content changes at the same time. Also take this as an opportunity to remove the separation between "common" and "mplayer" sources in the Makefile. ("common" used to be shared between mplayer and mencoder.)

demux: rewrite probing and demuxer initialization Get rid of the strange and messy reliance on DEMUXER_TYPE_ constants. Instead of having two open functions for the demuxer callbacks (which somehow are both optional, but you can also decide to implement both...), just have one function. This function takes a parameter that tells the demuxer how strictly it should check for the file headers. This is a nice simplification and allows more flexibility. Remove the file extension code. This literally did nothing (anymore). Change demux_lavf so that we check our other builtin demuxers first before libavformat tries to guess by file extension.

stream: remove padding parameter from stream_read_complete() Seems like a completely unnecessary complication. Instead, always add a 1 byte padding (could be extended if a caller needs it), and clear it. Also add some documentation. There was some, but it was outdated and incomplete.
