1c01b50ada audioconvert: fix mixed usage of gint and gint32 in int matrix 
This is a fixup for b2db18cda2
audioconvert: avoid float calculations when mixing integer-formatted channels

The int matrix was using gint and gint32 synonymously, which can theoretically
cause problems if gint and gint32 are actually different types.

b2db18cda2 audioconvert: avoid float calculations when mixing integer-formatted channels 
The patch calculates a second channel mixing matrix from the current one. The
matrix contains the original values * (2^10) as integers. This matrix is used
when integer-formatted channels are mixed.

On a ARM Cortex-A8, single core, 800MHz this improves performance in a
testcase from 29s to 9s for downmixing 6 channels to stereo.

3dc3aa4e3b audioconvert: Eliminate unsigned quantizers 
audio_convert_convert unpacks to default format (signed) before calling
quantize, and the unsigned variants were equivalent to signed anyway,
so we just get rid of them.

7b398701cf audioconvert: Avoid int division in quantization 
Since range size is always 2^n, we can simply use modulo (implemented
with a bitmask).

The previous implementation used 64-bit integer division, which is
done in software on ARMv7. Although the divisor was constant, the
division could not be transformed into "multiplication by magic number"
since the dividend was 64-bit.

The now-unused and not-so-fast gst_fast_random_(u)int32_range functions
were removed.

Also, implementing bug fixes:

1) ADD_DITHER_TPDF_HF_I no longer discards bias.

2) We change TPDF's noise range to be the same as RPDF's. Previously,
RPDF's noise ranged:
  { bias - dither, bias + dither }
while TPDF's noise ranged:
  { bias/2 - dither/2, bias/2 + dither/2 - 1 } +
  { bias/2 - dither/2, bias/2 + dither/2 - 1 } =
  { bias - dither, bias + dither - 2 }
Now, both range:
  { bias - dither, bias + dither - 1 }

6c6619a669 audioconvert: never do mixing for 1->1 channel conversions 
MONO and NONE position are the same, for example, but in
general there isn't much to do here for such a conversion.

Fixes problem in audioconvert, which would end up using
a mixmatrix when converting between different mono format
because it thinks MONO positioning is different from
unpositioned channels, which is not the case in this
special case. The mixmatrix would end up being 0.0 so
audioconvert would convert to silence samples.
