Only calculate mid-side signal when necessary (#567) 
The calculation of the mid-side signal components is moved, so this
is only performed when necessary. This gives a speed up of about
2% for preset 1 on a representative sample

Fix mistakes in _compute_best_predictor_limit_residual_intrin_* (#572) 
I made a few mistakes in these functions, adding instead of or-ing
and xor-ing instead of or-ing. The issue linked below seems to
relate to something completely different, but it is in fact a
result of triggering these mistakes further down the line.

Martijn van Beurden c10b059588 Limit hexdump characters to what is allowed in UTF-8 
CI tests failed on MacOS printf using a non-UTF8 locale, printing
characters for bytes values above 127. To have a consistent
interface, only print characters with a byte value lower than
128.

Martijn van Beurden 5b145aff12 Convert asserts into explicit checks 
An assert checking whether the bit depth of a FLAC file was valid
was triggered by fuzzing. This assert is converted to a explicit
check.

Similarly, an assert was triggered with a file of sample rate 0
when trying to add seekpoints spaced with seconds.

variant for this function. Execution time is halved.
