histedit: replace various nodes lists with replacement graph (and issue3582)
This changeset rewrites the change tracking logic of histedit to record every
operation it does. Tracked operations record the full list of "old" node that
will eventually be removed to the list of new nodes that replace it. Operations
on temporary nodes are tracked too. Dropped changesets are also recorded as an
"old" node replacement by nothing. This logic is similar to the obsolescence
marker one and will be used for this purpose in later commit.
This new logic implies a big amount of change in the histedit code base.
histedit action functions now always return a tuple of
(new-ctx, [list of rewriting operations])
The old `created`, `replaced` and `tmpnodes` are no longer returned and stored
during histedit operation. When such information is necessary it is computed
from the replacement graph. This computation is done in the `processreplacement`
function.
The `replacemap` is also dropped. It is computed at the end of the command from the
graph. The `bootstrapcontinue` methods are altered to compute this different kind of
information.
This new mechanism requires much less information to be written on disk.
Note:
This changes allows a more accurate bookmark movement. bookmark on dropped
changeset are now move of their parent (or replacement of their parent)
instead of their children.
This fix issue3582

Values in ``.hg/hgrc`` override those in ``$HOME/.hgrc``, and these override settings made in the global ``/etc/mercurial/hgrc`` configuration. See |hgrc(5)|_ for details of the contents and format of these files. ``.hgignore`` This file contains regular expressions (one per line) that describe file names that should be ignored by **hg**. For details, see |hgignore(5)|_. ``.hgsub`` This file defines the locations of all subrepositories, and tells where the subrepository checkouts came from. For details, see :hg:`help subrepos`. ``.hgsubstate`` This file is where Mercurial stores all nested repository states. *NB: This file should not be edited manually.* ``.hgtags`` This file contains changeset hash values and text tag names (one of each separated by spaces) that correspond to tagged versions of the repository contents. The file content is encoded using UTF-8. ``.hg/last-message.txt`` This file is used by :hg:`commit` to store a backup of the commit message in case the commit fails. ``.hg/localtags`` This file can be used to define local tags which are not shared among repositories. The file format is the same as for ``.hgtags``, but it is encoded using the local system encoding. Some commands (e.g. revert) produce backup files ending in ``.orig``, if the ``.orig`` file already exists and is not tracked by Mercurial, it will be overwritten.
