Clean out string/character mentions from QByteArray docs

In some places QByteArray does interpret bytes as characters and a
sequence of them as a text string; everywhere else, however, it now
refers to them as bytes.

Add a section to the class doc explaining how char* pointers are
interpreted; the handling of '\0'-termination is surely familiar to
most readers, but making it explicit provides contrast for the
explanation of there being no such special treatment of '\0' bytes
when a stard address and length are given.

Also mention in the class doc that interaction with QString is done
via UTF-8 encoding and can be avoided by defining a macro. Shorten, in
light of that, the description of that encoding where it appears in
affected methods.

In the process, clean up lots of phrasings.
