ape: provide two additional bytes in buffer for old MAC versions
...
Range coder in 3.90-3.95 overread two bytes in the final normalize.

ape: make version-dependent decoding functions called via pointers
...
This will help in supporting old versions, e.g. version 3.93 uses the same
range coder but different predictor and version 3.82 uses different range
coder and predictor. Also this should not make decoding newer versions slower
by introducing additional checks on versions.

apedec: allow the user to set the maximum number of output samples per call
...
It makes sense in some cases to split up the output packet to save on memory
usage (ape frames can be very large), but the current/default size is
arbitrary. Allowing the user to configure this gives more flexibility and
requires minimal additional code.

doxygen: Prefer member groups over grouping into modules

Before this, almost all module groups have been used for grouping functions
and fields in structures semantically. This causes them to not appear
properly in the file documentation and needlessly clutters up the "Modules"
index.
Additionally, this commit streamlines some spelling and appearances.
