ac3parse: Support switching alignment on-the-fly
...
This allows switching of alignment for E-AC3 streams at run-time. This
is requested by downstream elements via a custom event.

ac3parse: Add support for IEC 61937 alignment
...
When pushing out buffers over S/PDIF or HDMI, IEC 61937 payloading
requires each buffer to contain 6 blocks from each substream. This adds
code to collect all the frames needed to meet this requirement before
pushing out a buffer.

ac3parse: fix buffer duration on blocks-per-frame change
...
The gst_base_parse_set_frame_rate call was predicated on a change to
sample rate, duration or profile. However, the block count per frame can
also change between packets, which would result in incorrect buffer
durations.
