sshpeer: don't read from stderr when that behavior is disabled

We previously prevented the creation of doublepipe instances when
we're not supposed to automatically read from stderr. However,
there were other automatic calls to read from stderr that were
undermining this effort.

This commit prevents all automatic reads from stderr from occurring
when they are supposed to be disabled.

Because stderr is no longer being read, we need to call "readavailable"
from tests so stderr is read from.

Test output changes because stderr is now always (manually) read after
stdout. And, since sshpeer no longer automatically tends to stderr,
no "remote: " messages are printed. This should fix non-deterministic
test output.

FWIW, doublepipe automatically reads from stderr when reading from
stdout, so I'm not sure some of these calls to self._readerr() are
even needed.

============================================
Testing obsolescence markers push: Cases B.5
============================================

Mercurial pushes obsolescences markers relevant to the "pushed-set", the set of
all changesets that requested to be "in sync" after the push (even if they are
already on both side).

This test belongs to a series of tests checking such set is properly computed
and applied. This does not tests "obsmarkers" discovery capabilities.

Category B: pruning case
TestCase 5: Push of a children of changeset which successors is pruned

B.5 Push of a children of changeset which successors is pruned
==============================================================

.. This case Mirror A.4, with pruned changeset successors.
