0d333d8d44 video-converter: add table based matrix8 implementation 
Based on patch from Mozzhuhin Andrey <nopscmn at gmail.com>

Add a table based matrix8 multiplication implementation. The algorithm
does not do any clipping so we need to make sure we never call this on
input that might need to be clipped. In general, this algorithm is
2 times faster than the orc optimized one and would be chosen for all
RGB -> YUV conversions and some YUV->YUV and RGB->RGB conversions.

40f4daffd1 volume: Explicitly cast integers to doubles and then back to integers after multiplication 
gcc 4.9.1 on ARM seems to have a bug that causes it to cast the float to an
integer first, resulting in a 0 scale factor for volume < 1.0.

As a side effect this change here will also improve accuracy of the result a
bit because we go via doubles instead of floats.

557c2c9be1 audiobasesink: Reset audio clock if necessary 
When the ringbuffer is deactivated and then acquired, if the audio clock
provided by the sink gets reset to zero, we need to add an offset to the
clock to make sure that subsequent samples are written out at the right
times. While we need to leave this to derived classes to take care of
when they provide their own clock (since that clock may or may not be
reset to zero), we can do this ourselves if we know the provided clock
is our own (which does reset to zero on a re-acquire).

35bd289be3 tests: fix crashes in {audio,video}{decoder,encoder} tests on 32-bit 
Don't feed 64-bit integer variable into vararg function that expects
an unsigned integer to go with GST_TAG_TRACK_NUMBER. This would
cause crashes on 32-bit platforms, and if not that then test
failures if the comparisons fail later (at least on big endian
platforms).
