A bug in !1700 cause the encoder to pass all parameters into all layers (independent of the specified target layer)

At the encoder there are long parameters like "--QP=32" and short parameters like "-q 32"

For layer parameters -lx (with x being the layer index) the encoder always assumes that
-lx is followed by two parameters, which is only true for short type parameters.

This checks for "--" in the first parameter following -lx and only reads a second parameter,
if "--" is not found at the beginning.

Renumbering level according to major*16+minor*3, with maximum level now
15.5 (not 8.3).

- also disable decoder conformance checks that fail for multi-layer streams apparently without valid reason
- rename Picture::layer to temporalId, because temporal ID is stored in this member variable

Document updated

Assign correct default values (1) to collocated chroma flags in
SPS. Note that default values are used only for non-420 chroma formats.
Modify and clean up CCLM code to not unnecessarily rely on collocated
chroma flags for non-420 chroma formats.

m_cEncLib.setNoAlfConstraintFlag                            ( !m_ccalf );
should be corrected as
m_cEncLib.setNoCCAlfConstraintFlag                          ( !m_ccalf );
