This fixes clipping if the encoder input used the full 16 bit
input range (samples with a magnitude below 16383 worked fine).
The filtered subband samples should be 15 bit maximum, while
the code earlier produced them scaled to 16 bit.

This makes the decoder output have double the magnitude
compared to before.

The spec reference samples doesn't test the QMF at all, which
was why this part slipped past initially.

They allow to implement the if/then/else logic, which cannot be
implemented otherwise.

For example the expression:
A*B + not(A)*C

always evaluates to NaN if B is NaN, even in the case where A is 0.

fixes the tests on big-endian systems

Fixes fate-targa-conformance-CCM8 and fate-targa-conformance-UCM8.

to rgb24 is thus necessary for identical CRCs on big and little endian

In 1bpp mode, interpret skip&0x80 as "start a new line" instead of "go to next line", this is almost the same except for the first line which was always skipped before and caused to try to write an extra line at the end of the frame (ticket #226).

AVFMT_NOTIMESTAMPS for crc, as it ignores the timestamps.
AVFMT_VARIABLE_FPS for framecrc, as it prints dts.

Many FATE changes, because avconv is no longer duplicating frames in
those tests.
Also added -vsync 0 for some tests to prevent avconv from dropping
frames until it can be fixed more properly.
