filemerge: put temporary files in single temp dir by default
The feature introduced in D2888 seems like a pure improvement to
me. It makes the names' of temporary file easier to read. Let's have
it always enabled.
I also removed the config option for the path prefix because it
doesn't seem useful. I asked Kyle (the author of the feature) about it
and he couldn't think of a reason to keep it. I suspect it was just
that we to have a config to turn it on/off while it was experimental,
so it might as well be a configurable prefix then.

====================================
Testing head checking code: Case D-5
====================================
Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.
This case is part of a series of tests checking this behavior.
Category D: remote head is "obs-affected" locally, but result is not part of the push
TestCase 5: multi-changeset branch, split on multiple other, (head on its own new branch)
.. old-state:
..
.. * 2 branch (1 changeset, and 2 changesets)
..
.. new-state:
..
.. * 1 new branch superceeding the head of the old-2-changesets-branch,
.. * 1 new changesets on the old-1-changeset-branch superceeding the base of the other
..
.. expected-result:
..
.. * push the new branch only -> push denied
.. * push the existing branch only -> push allowed
.. /!\ This push create unstability/orphaning on the other hand and we should
.. probably detect/warn agains that.
