revlog: decouple caching from addrevision callback for addgroup
For changesets, it is useful to cache the content as it will almost
always be processed afterwards. For manifests on the other hand, the
content is often not used directly as there is a fast path for deltas.
Explicitly disable the cache in exchangev2's manifest handling for that
reason.

branchmap: update rev-branch-cache incrementally
Historically, the revision to branch mapping cache was updated on demand
and shared via bundle2 to avoid the cost of rebuilding on first use.
Use the new `register_changeset` callback and update rbc directly on
every change. Make the transfer of the bundle part redundant, but keep
it for the moment to avoid the test churn.
Over all, "hg unbundle" for large bundles is less than 1.8% slower for
different larger repositories and that seems to a reasonable trade off.

repository: introduce register_changeset callback
The new callback is called whenever a changeset is added to the repository
(commit, unbundle or exchange). Since the bulk operations already parse
the changeset (readfiles or full changesetrevision), always use the
latter to avoid redundant lookups. The first consumer of the new
interface needs to look at extra.

changelog: move branchinfo to changelogrevision
The function parses the extra dictionary after looking up the
changelogrevision. To avoid duplicated look up, it is better to provide
it as property of changelogrevision instead. Keep the function for a
release cycle as at least the topic extension depends on it.

purge: move extension into core mercurial
The motivation is simple: it's nicer to avoid gating basic
functionality.
To reduce the risk of people shooting themselves in the feet, `--confirm` is now
the default, unless the extensions is loaded..
For review of the body of the purge command, use this instead of what
hg/phabricator will show (the block of code is modified, not just
moved):

filemerge: add a hacktastic version of internal:merge3 for merge diffs
This is a version of merge3 that always reports success, so that
conflict markers get preserved without us having to implement conflict
storage for in-memory merge. Credit to martinvonz for the idea. The
only planned consumer of this "merge tool" is my upcoming merge-diffs
functionality, though I suspect it could be useful in other ways.

resolve: also detect new :mergediff conflict markers
The conflict markers created by `:mergediff` were not detected as
conflicts, which affects both `commands.resolve.mark-check` and
`mergetools.<tool>.check`. This patch fixes that.
The new regex it uses for finding conflict markers is less restrictive
because it `:mergediff` doesn't follow the `<<<<<<<` and `>>>>>>>`
lines by a space (and a description). Hopefully lines like that don't
give too many false positives. We can add back the space and make
`:mergediff` add trailing spaces if it turns out to be a
problem. OTOH, there will always be some false positives and we have
ways of overriding the checks already.
This patch can go onto the default or stable branch, depending on how
much we care about an experimental feature.

share: rework config options to be much clearer and easier
Recently I implemented various boolean configs which control how to behave when
there is a share-safe mismatch between source and share repository. Mismatch
means that source supports share-safe where as share does not or vice versa.
However, while discussion and documentation we realized that it's too
complicated and there are some combinations of values which makes no sense.
We decided to introduce a config option with 4 possible values which
makes controlling and understanding things easier.
The config option `share.safe-mismatch.source-{not-}safe` can have
following 4 values:
* abort (default): error out if there is mismatch
* allow: allow to work with respecting share source configuration
* {up|down}grade-abort: try to {up|down}grade, if it fails, abort
* {up|down}grade-allow: try to {up|down}grade, if it fails, continue in allow
mode
I am not sure if I can explain 3 config options which I deleted right now in
just 5 lines which is a sign of how complex they became.
No test changes demonstrate that functionality is same, only names have changed.

re2: feed unicode string to re2 module when necessary
My previous test were using the `pyre2` Python project, that wrap the Google RE2 library
in python as a `re2` module and accept bytes as input. However the `fb-re2`
Python project is also offering a wrapping of the Google RE2 library in python
as a `re2` module ans accept only unicode on python3. So we detect this
situation and convert thing to unicode when necessary.
Hooray…
We should consider using a rust wrapping for regexp handling. We needs regexps
in Rust anyway and this give use more control with less variants and more
sanity.
