bundle2: support for unbundling parameter value The unbundler now understand parameter value. introduced in the previous changeset.

bundle2: support for bundling parameter value Parameter can now have a value. We use a `<name>=<value>` form inspired from capabilities. There is still no kind of escaping in the name or value, yet.

bundle2: clarify stream parameter design in the documentation Stream level parameter have very restricted use case. Clarify why we chosen a textual format and point that applicative data goes in applicative parts.

repoview: add non-global tags to candidate list for blocking hidden changesets Previously, only bookmarks would be considered for blocking a changeset from being hidden. Now, we also consider non-global tags. This is helpful if we have local tags that might be hard to find once they are hidden, or tag that are added by extensions (e.g. hggit or remotebranches).

histedit: select the lowest rev when looking for a root in a revset (bc) When we specify a revision or a revset we just get the last element from the list. For revsets this can lead to unintended effects where you specify a revset like only() but instead histedit selects the highest revision in the set as root. Therefore we should always use the lowest revision number as root.

bundle2: support for unbundling simple parameter the unbundler now understand simple list of parameter.

bundle2: support bundling simple parameter This changeset add bundling capacity for simple parameters, not value or any special case are handled.

bundle2: make sure the unbundler refuse non bundle2 stream We now make use of the magic string at the beginning of the file.

bundle2: a very first version of bundle2 unbundler This changeset introduce an unbundler class to match the bundle2 bundler. It is currently able to unbundle an empty bundle2 only and will gain more feature at the same pace than the bundler. It also comes with its special extension command in test.

bundle2: very first version of a bundle2 bundler This changeset is the very first of a long series. It create a new bundle2 module and add a simple class that generate and empty bundle2 container. The module is documented with the current state of the implementation. For information about the final goal you may want to consult the mercurial wiki page: http://mercurial.selenic.com/wiki/BundleFormat2 The documentation of the module will be updated with later patches adding more and more feature to the format. This patches also introduce a test case. This test case build and use its own small extension that use the new bundle2 module. Since the new format is unable to do anything right now, we could not use real mercurial code to test it. Moreover, some advanced feature of the bundle2 spec will not be used by core mercurial at all. So we need to have them tested.
