avwait: Rename timecodewait to avwait, add modes

Browse source 
Renamed timecodewait to avwait. Added running-time and video-first
modes. Default mode is timecode (the previous behaviour).

/**
* SECTION:element-timecodewait
* SECTION:element-avwait
*
* This element acts like a synchronized audio/video "level". It gathers
* all audio buffers sent between two video frames, and then sends a message
* that contains the RMS value of all samples for these buffers.
* This element will drop all buffers until a specific timecode or running
* time has been reached. It will then pass-through both audio and video,
* starting from that specific timecode or running time, making sure that
* audio starts as early as possible after the video (or at the same time as
* the video). In the "audio-after-video" mode, it only drops audio buffers
* until video has started.
