New Revision: 19330
   Changeset: http://cvs.mythtv.org/trac/changeset/19330




Refs #2287. Make keyframe map syncing a bit more efficient. First we allow the NVP to pass -1 as the end keyframe to request, which means we want all keyframes greater than the start keyframe this avoids 1 of the two network roundtrips. Second, we use QMap::lowerBound() to find the first keyframe greater than or equal to the start keyframe, and then iterate until we reach the end of the map, this doesn't change the big O performance but makes the code about a 15 times faster in practice.
