Doc: Improve QBuffer::open description

Browse Source 
Explain the method, instead of just linking to the base method.

Call the argument 'mode' instead of 'flags', like it is done in
the base class.

Force the mentioned QIODeviceBase flags to be links. Use fully
qualified name for the first flag mentioned, but use the short form
for the rest to improve readability.

\reimp
Opens the buffer using \a mode flags, returning \c true if successful;
otherwise returns \c false.
Unlike QFile, opening a QBuffer QIODevice::WriteOnly does not truncate it.
However, pos() is set to 0. Use QIODevice::Append or QIODevice::Truncate to
change either behavior.
The flags for \a mode must include \l QIODeviceBase::ReadOnly,
\l WriteOnly, or \l ReadWrite. If not, an error is printed and
the method fails. In any other case, it succeeds.
Unlike \l QFile::open(), opening a QBuffer with \l WriteOnly
does not truncate it. However, \l pos() is set to \c{0}.
Use \l Append or \l Truncate to change either behavior.
