singlehead: making config item a bool again

with the use of `configsuboptions`, the main config item has become
a string (unless it's just the default value).

This makes it in particular hard to override in a cascade of HGRC files,
as we do in Heptapod to re-allow multiple heads on specific repositories
while the default behaviour is to forbid them. The added test case reflects
that use-case

  abort: rejecting multiple heads on branch "branch_A"

Test that config can be overriden as the boolean it is
------------------------------------------------------

  $ cat <<EOF >> $TESTTMP/single-head-server/.hg/hgrc
  > [experimental]
  > single-head-per-branch = no
  > EOF

Because of previous test, we'll also push c_aL0 and c_aM0.

  $ hg out -T "{desc}\n"

  c_aL0
  c_aM0

Let's make a new head and push everythin. The server feedback will mention
exactly one new head because c_aM0 is closed.

  $ hg up 'desc("c_aG0")'
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ mkcommit c_aN0
  created new head
  $ hg push -f
