server: introduce a 'experimental.single-head-per-branch' option

When the option is set, the repository will reject any transaction adding
multiple heads to the same named branch.

For now we reject all scenario with multiple heads. One could imagine handling
closed branches differently. We prefer to keep things simple for now. The
feature might get extended later. Branch closing is not the best experience
Mercurial has to offer anyway.
