/* Playlist begins with "# x\n" where x is the total number of records.
* Each record begins with "# x y\n" where x is record index, y is its size in bytes.
* Records are sorted according to mkplist.c:/^cmpmeta function.
* This makes it somewhat easy to just load the whole playlist into memory once,
* map all (Meta*)->... fields to it, saving on memory allocations, and using the same
* data to provide poor's man full text searching.
* Encoding: mkplist.c:/^printmeta/.
* Decoding: zuke.c:/^readplist/.
