[Development] Proposal: "rebranding" QMF as QtMail

[Robin Burchell]

Hello folks,

After some build system reworking recently and a little discussion
amongst the interested parties (Matt Vogt, Valerio), I'd like to
propose renaming QMF (Qt Messaging Framework) to QtMail with the
longer term goal of making it a module of Qt properly - no longer a
labs project.

QMF's naming is historical: QMF originally handled other types of
messages than purely mail (SMS/MMS also, for instance). This has not
been the case for quite some time - QMF now handles *only* email, so
this renaming makes the whole thing sound a bit less meta and less
awkward.

The repository is currently comprised of two main libraries:
QmfMessageServer and QmfClient. I would propose:

QmfClient => QtMail
QmfMessageServer => QtMessageServer

Classes in QMF are already using the QMail* prefix.

Any objections?

BR,
Robin
