We've found a severe perf regression in `hg update` caused by the path conflict
checking code. The next patch will disable this by default.

When a dirstate backup is restored, it is possible that no actual changes to
the dirstate have been made. In this case, the backup is still a hardlink
to the original dirstate.
Unfortunately, `os.rename` silently fails (nothing happens, and no error
occurs) when `src` and `dst` are hardlinks to the same file. As a result,
the backup is left lying around. Over time, these files accumulate.
When restoring dirstate backups, check if the backup and the dirstate are
the same file, and if so, just delete the backup.

I'm not sure why these weren't working on Windows. The failures were generally
in the style of:
- remote: phase-move: cb9a9f314b8b07ba71012fcdbc544b5a4d82ff5b: 1 -> 0
+ remote: "phase-move: $HG_NODE: $HG_OLDPHASE -> $HG_PHASE"
and
- abort: pretxnclose-bookmark.force-forward hook exited with status 1
- [255]
+ abort: pretxnclose-bookmark.force-public hook exited with status 255
+ [255]
These failures originated in 5625d0ddc285::6e3e88681b23.
Previously, the second last test (context.arbitraryfilectx(..)) returned True on
Windows. I changed the repo setup sequence to import a patch, so that way the
repo would have a proper symlink. That made the last test fail, since it is
comparing files in wdir(), one of which is not the expected symlink.
Apparently the (feature !) line matching doesn't work well with (no-eol), so I
had to conditionalize the test instead of the output.
A recent refactor added a layer of abstraction to the dirstate which makes doing
things like 'foo in dirstate' now require some extra Python attribute lookups.
This is causing a 100ms slow down in hg status for mozilla-central.
The fix is to hoist the inner dict's functions onto the main class once the lazy
loading it complete, as well as store the actual functions before doing the
status loop (as is done for other such functions).
In my testing, it seems to address the performance regression, but we'll
need to see the perf run results to know for sure.

Before the recent refactor, we would not load the entire map until it was
accessed. As part of the refactor, that got lost and even just trying to load
the dirstate parents would load the whole map. This caused a perf regression
(issue5713) and a regression with static http serving (issue5717).
Making it lazy loaded again fixes both.

A future diff will move the lazy loading aspect of dirstate to the dirstatemap
class. This means it requires a slightly different strategy of clearing than
just reinstantiating the object (since just reinstantiating the object will
lazily load the on disk data again later instead of remaining permanently
empty).
So let's give it it's own clear function.

The same applies to '?' if --quiet is used (or any of the other states if some
of -marduic is specified), but I couldn't figure out how to express that
clearly.
This seems a bit hacky, but works well. There should be no reason that
static-http repo had to load dirstate.
Initially I tried to proxy os.stat() call through vfs so that statichttpvfs
could hook it, but there wasn't a good error value which the statichttpvfs
could return to get around the util.filestat issue.
If we're going to use the user's installed and configured hg command
(which we do since a4a6cb293e63), we should prevent devel-warn messages
from interfering with locating it.
The short options "-c" and "-C" may be confusing for a novice reading the
documentation. Let's try to be more explicit, also mentioning the equivalent
long options ("--check" and "--clean") in the comments.
If the legacy pager extension is enabled, a pager is started through repo.ui
at dispatch._runcommand(). After that, mqcommand() creates a qrepo with a
fresh repo.baseui, at which point pager information was lost and another pager
would be spawned by the modern pager interface.
This is a minimal workaround for the problem.
Currently, specifying both a line-range pattern and a bare file pattern
results in an AND operation whereas we probably want an OR so that bare file
patterns are like a line-range pattern with all lines specified.
So, until this works as expected, we disable this.
When a file is binary patch.trydiff() would yield None for 'hunkrange'. Handle
this case in the hunksfilter() callback.
Add tests with and without diff.git option as binary handling differs
depending on this option's value.
Reverts 5b2411bab704 and replaces it with a more general solution.
- works for both rpm and deb
- sidesteps eventual problems with local extensions that have nothing to do with
the build process (hg-git, for example, fails with version 4.4 because
ccf72242b638 removed peerrepository, and hg-git still uses it as of 0.8.9)
Effect-flags config was in flight while the previous evolve config renaming
was written. Now that both landed, gather effect-flags in
experimental.evolution like the others evolve-related configurations.

Yuja's comment on the original obsfate about how we would translate obsfate
and the recent discussions about exposing users to new concepts and names lead
have led me to think that 'obsfate' should be treated as internal jargon. End-
users should not be aware of obsfate, so we replace 'obsfate' by 'obsolete' in
changeset_printer.
It will be easier to understand for end-users, easier to translate and closer
to the original Evolve obsfate output.
I'm aware it's extremely late in the cycle but I think it's an UX improvement
for the end-users.

An empty entry in the revlog may happen for two reasons:
- when the file is empty, and the revlog stores a snapshot;
- when there is a merge and both parents were identical.
`hg debugindex -m | awk '$3=="0"{print}' | wc -l` gives 1917 of such entries
in my clone of pypy, and 113 on my clone of mercurial.
These empty revision may be located at the end of a sparse chain, and in some
special cases may lead to read relatively large amounts of data for nothing.
`dirstate._nonnormalset` has been moved to `dirstate._map.nonnormalset` by
822ff2522caf (dirstate: move nonnormal and otherparent sets to dirstatemap)
and is guaranteed to be existed.
Let's update fsmonitor code to use the new `nonnormalset`. Thix fixed a perf
regression that slows down `hg status` by 0.5 seconds in one of our
production repos.

Once in a while, test-nothing.t finished before test-failure.t or
test-failure-copy.t (I haven't checked which one actually gets run
first). Since there already are two tests that will fail in the same
way, just run those two instead so the diff will be reproducible and
not timing-dependent.
The test case was added in d5f1ee5ea1d3 (run-tests: handle --jobs and
--first gracefully, 2014-10-09), and I have checked that backing that
out results in two failures being printed. Note that the summary may
still include multiple tests even if --first is given, it's just that
the diff is only printed for the first failure.
