revlog: introduce an explicit tracking of what the revlog is about
Since the dawn of time, people have been forced to rely to lossy introspection
of the index filename to determine what the purpose and role of the revlog they
encounter is. This is hacky, error prone, inflexible, abstraction-leaky,
<insert-your-own-complaints-here>.
In f63299ee7e4d Raphaël introduced a new attribute to track this information:
`revlog_kind`. However it is initialized in an odd place and various instances
end up not having it set. In addition is only tracking some of the information
we end up having to introspect in various pieces of code.
So we add a new attribute that holds more data and is more strictly enforced.
This work is done in collaboration with Raphaël.
The `revlog_kind` one will be removed/adapted in the next changeset. We expect
to be able to clean up various existing piece of code and to simplify coming
work around the newer revlog format.

When they occur, it reverts *all* changes and moves forward, letting the conflict resolving patch fix collisions. Unfortunately, non-conflicting changes, like the addition of the "c" file in p1.1 patch are reverted too. Just to say that manifest not listing "c" here is a bug. $ cd .. $ hg convert darcs-repo darcs-repo-hg initializing destination darcs-repo-hg repository scanning source... sorting... converting... 4 p0 3 p1.2 2 p1.1 1 p2 0 p3 $ hg log -R darcs-repo-hg -g --template '{rev} "{desc|firstline}" ({author}) files: {files}\n' "$@" 4 "p3" (test@example.org) files: dir/d dir/d2 dir2/d f ff 3 "p2" (test@example.org) files: a dir/d dir/d2 f 2 "p1.1" (test@example.org) files: 1 "p1.2" (test@example.org) files: a b 0 "p0" (test@example.org) files: a $ hg up -q -R darcs-repo-hg $ hg -R darcs-repo-hg manifest --debug 7225b30cdf38257d5cc7780772c051b6f33e6d6b 644 a 1e88685f5ddec574a34c70af492f95b6debc8741 644 b 37406831adc447ec2385014019599dfec953c806 644 dir2/d b783a337463792a5c7d548ad85a7d3253c16ba8c 644 ff #if no-outer-repo try converting darcs1 repository $ hg clone -q "$TESTDIR/bundles/darcs1.hg" darcs $ hg convert -s darcs darcs/darcs1 2>&1 | grep darcs-1.0 darcs-1.0 repository format is unsupported, please upgrade #endif
