revlog-compression: use zstd by default (if available)

As see in changeset bb271ec2fbfb, zstd is 20% to 50% faster for reading and
writing.

Use take advantage of the new config behavior to try zstd by default, falling
back to zlib is zstd is not available on that plateform.

============================================
Testing obsolescence markers push: Cases D.3
============================================

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 D: Partial Information Case
TestCase 3: missing prune target (prune not in "pushed set")

D.3 missing prune target (prune not in "pushed set")
====================================================
