changelog: add way to call the reachableroots C implementation
This patch is part of a series of patches to speed up the computation of
revset.reachableroots by introducing a C implementation. The main motivation is
to speed up smartlog on big repositories. At the end of the series, on our big
repositories the computation of reachableroots is 10-50x faster and smartlog on
is 2x-5x faster.
This patch allows us to call the new C implementation of reachableroots from
python by creating an entry point in the changelog class.

$ hg shelve -h
hg shelve [OPTION]... [FILE]...
save and set aside changes from the working directory
Shelving takes files that "hg status" reports as not clean, saves the
modifications to a bundle (a shelved change), and reverts the files so
that their state in the working directory becomes clean.
To restore these changes to the working directory, using "hg unshelve";
this will work even if you switch to a different commit.
When no files are specified, "hg shelve" saves all not-clean files. If
specific files or directories are named, only changes to those files are
shelved.
Each shelved change has a name that makes it easier to find later. The
name of a shelved change defaults to being based on the active bookmark,
or if there is no active bookmark, the current named branch. To specify a
different name, use "--name".
To see a list of existing shelved changes, use the "--list" option. For
each shelved change, this will print its name, age, and description; use "
--patch" or "--stat" for more details.
To delete specific shelved changes, use "--delete". To delete all shelved
changes, use "--cleanup".
(use "hg help -e shelve" to show help for the shelve extension)
options ([+] can be repeated):
-A --addremove mark new/missing files as added/removed before
shelving
--cleanup delete all shelved changes
--date DATE shelve with the specified commit date
-d --delete delete the named shelved change(s)
-e --edit invoke editor on commit messages
-l --list list current shelves
-m --message TEXT use text as shelve message
-n --name NAME use the given name for the shelved commit
-p --patch show patch
-i --interactive interactive mode, only works while creating a shelve
--stat output diffstat-style summary of changes
-I --include PATTERN [+] include names matching the given patterns
-X --exclude PATTERN [+] exclude names matching the given patterns
--mq operate on patch repository
(some details hidden, use --verbose to show complete help)
shelving in an empty repo should be possible
(this tests also that editor is not invoked, if '--edit' is not
specified)
