tagcache: distinguish between invalid and missing entries

The TortoiseHg repo has typically not had a newly applied tag accessible by name
for recent releases, for unknown reasons.  Deleting and rebuilding the tag cache
doesn't fix it, though deleting the cache and running `hg log -r $new_tag` does.
Eventually the situation does sort itself out for new clones from the server.
In an effort to figure out what the issue is, Pierre-Yves David suggested
listing these entries in the debug output more specifically.

This isn't complete yet- the second test change that says "missing" is more like
"invalid", since it was truncated.  The problem there is the code that reads the
raw array truncates any partial records and then fills it with 0xFF, which
signifies that it is missing.  As a side note, that means the check for the
length when validating an existing entry never fails.

============================================
Testing obsolescence markers push: Cases C.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 C: advanced case
