basectx: add _matchstatus method for factoring out last of parentworking logic This patch paves the way to allow a workingctx to override the match object with a custom 'bad' method for cases where status is sent a directory pattern.

workingctx: use inheritance for _buildstatus while keeping the fastpath This patch maintains the fast path for workingctx which is to not build a manifest if the working directory is being compared to its parent since, in this case, we can just copy the parent manifest.

localrepo: remove unneeded unpacking of r This unpacking is unneeded now because previous patches have removed the need for this method to modify each of these variables in favor of passing the whole set around to pre/post hook methods of the corresponding context object.

localrepo: call _poststatus hook instead of hardcoding symlink knowledge

workingctx: add _poststatus method to call _filtersuspectsymlink With this patch, we are one step closer to removing 'if ... else' logic in localrepo.status for testing if the context is the working directory or not. Future patches will replace those blocks of code with a call to the context's _poststatus hook so that each context object will do the right thing depending on the situation.

context: add a no-op _poststatus method This patch adds a private _poststatus method so that certain contexts, such as workingctx, can add custom post-processing to status.

localrepo: call _prestatus hook instead of hardcoding dirstate knowledge

workingctx: add _prestatus method to call _dirstatestatus With this patch, we are one step closer to removing 'if ... else' logic in localrepo.status for testing if the context is the working directory or not. Future patches will replace those blocks of code with a call to the context's _prestatus hook so that each context object will do the right thing depending on the situation.

context: add a no-op _prestatus method This patch adds a private _prestatus method so that certain contexts, such as workingctx, can add custom pre-processing to status.

localrepo: use _buildstatus from context
