namespaces: add bookmarks to the names data structure This marks the first use of abstracting our different types of named objects (bookmarks, tags, branches, etc.) and upcoming patches will use this to simplify logic.

namespaces: add a convenience property for the weakref _repo

namespaces: pass repo to __init__ We store repo as a weakref so that we can prevent a cycle between namespaces and localrepo.

namespaces: add a function to turn single results into lists

namespaces: add a method to register new namespaces

namespaces: introduce a generic way to map between names and nodes This patch begins the work to provide a way to register a namespace to handle 'names'. Benefits of this would be, - improved templating: This would provide {name} which could output any branch, bookmark, tag, or any extension registered namespace all without having the extension doing any extra work - improved tab completion: Since this provides a single source of all 'names', tab completion would not need to know of each namespace - changeset lookup: Similar to before, a unified place to get all 'names' will allow finding changesets without any extension code having to reimplement this Also, d226fe36e362 has shown us that for internal code which expects a certain type of method or behavior, we should provide an easy way for extensions to check this behavior.

statichttprepo: update profile of __call__ in mock vfs object New code paths could fail because the old statichttprepo profile couldn't handle the usual parameters. Instead, reuse a more generic profile also used in readonlyvfs.

tests: avoid git diffstat singular/plural output difference 'git diff --stat' output changed with regard to the amount of changes/insertions/deletions shown. In older git versions (1.7.7.6), output was shown as: 2 files changed, 2 insertions(+), 1 deletions(-) In newer versions, output is shown as: 2 files changed, 2 insertions(+), 1 deletion(-) This patch uses a regex to handle both cases.

subrepo: add revert support without backup for git subrepos Previously, git subrepos did not support reverting. This change adds basic support for reverting when '--no-backup' is specified. A warning is given (and the current state is kept) when a revert is done without the '--no-backup' flag.

match: make 'always' and 'exact' functions, not classes There is no reason for classes 'always' and 'exact' not to be just functions that return instances the plain 'match' class.
