subrepo: add status support for ignored and clean files in git subrepos

revlog: addgroup checks if incoming deltas add censored revs, sets flag bit A censored revision stored in a revlog should have the censored revlog index flag bit set. This implies we must know if a revision is censored before we add it to the revlog. When adding revisions from exchanged deltas, we would prefer to determine this flag without decoding every single full text. This change introduces a heuristic based on assumptions around the Mercurial delta format and filelog metadata. Since deltas which produce a censored revision must be full-replacement deltas, we can read the delta's first bytes to check the filelog metadata. Since "censored" is the alphabetically first filelog metadata key, censored filelog revisions have a well-known prefix we can look for. For more on the design and background of the censorship feature, see: http://mercurial.selenic.com/wiki/CensorPlan

repair: define explicit local variable, don't reuse a comprehension variable The node ID used in strip bundle names is currently taken as the last iterated value in a list comprehension found much earlier in the function. This change makes the node selection more explicit at the cost of redundancy.

commands.paths: use ui.paths to show paths We now have an API for representing a collection of paths. Use it.

ui: represent paths as classes Many have long wanted for paths to have expanded functionality and flexibility. In order to make that transition possible, we need to start representing paths as something more than simple strings. This patch introduces two classes: 1) "path" for representing a single path instance 2) "paths" for representing a collection of "paths" Since we don't like patches that introduce new code without any consumers, we convert ui.expandpath() to use the new APIs internally. Upcoming patches will start exposing "path" instances to consumers that currently interface with string paths. The new "paths" attribute of ui is populated from config data the first time it is accessed. Since it isn't updated when the configs are modified, this could lead to some inaccurate caching behavior. It shouldn't be an issue, as paths information is typically not accessed until command dispatch, which occurs after the repository config and extensions have been loaded. Time will tell if we need to refresh paths information when the underlying config changes.

color: omit terminfo/win32 warning if non-interactive (issue4543) It's pretty annoying to be getting this warning when already the colour extension has no hope of working. If there isn't a human on the other end to to see the colours, there probably isn't a human either who cares about this warning. More likely, some script somewhere is gonna get confused with the warning output. Of course, if we still want to see the warning for some reason, we can always set --config ui.interactive=True.

incoming: hide help about use of --bundle option by default Pulling from incoming bundle can cause trouble such as missing phase movement, bookmarks and largefiles transfer. Average user won't need this option.

patch.applydiff: accept a prefix parameter This is preparation for upcoming patches that will add support for applying a patch within a subdirectory.
