manifest: remove _repo from manifestctx objects...
manifest: remove _repo from manifestctx objects We were storing the repo on the manifestctx objects so that they could access the manifestlog via repo.manifestlog, which would refresh the structure if it became out of date. This caused probems however when we want to have multiple manifest logs in memory at once, like when transitioning to tree manifest from flat manifests, since a tree manifest would try to access sub-trees via repo.manifestlog[node], which was the flat manifest. The solution is to just not store the repo, and instead store the manifestlog that created this context. This removes the invalidation when the in memory manifestlog becomes out of date, but people should probably not be keeping ctx's around that long anyway.

Mercurial's default format for showing changes between two versions of
a file is compatible with the unified format of GNU diff, which can be
used by GNU patch and many other standard tools.
While this standard format is often enough, it does not encode the
following information:
- executable status and other permission bits
- copy or rename information
- changes in binary files
- creation or deletion of empty files
Mercurial also supports the extended diff format from the git VCS
which addresses these limitations. The git diff format is not produced
by default because a few widespread tools still do not understand this
format.
This means that when generating diffs from a Mercurial repository
(e.g. with :hg:`export`), you should be careful about things like file
copies and renames or other things mentioned above, because when
applying a standard diff to a different repository, this extra
information is lost. Mercurial's internal operations (like push and
pull) are not affected by this, because they use an internal binary
format for communicating changes.
To make Mercurial produce the git extended diff format, use the --git
option available for many commands, or set 'git = True' in the [diff]
section of your configuration file. You do not need to set this option
when importing diffs in this format or using them in the mq extension.
