graft: move commit info building This moves the logic for generating the commit metadata ahead of the merge operation. The only purposae of this patch is to make subsequent patches easier to read, and there should be no behavior changes.

merge: support calculating merge actions against non-working contexts This is not currently used. It is instead a pre-requisite to performing non-conflicting grafts in memory, which a subsequent patch will do.

merge: refactor action calculation into function This pulls the code used to calculate the changes that need to happen during merge.update() into a separate function. This is not useful on its own, but is instead preparatory to performing grafts in memory when there are no potential conflicts.

dirstate: inline more properties and methods in status hg perfstatus -u on a working directory with 170,000 files, without this change: ! wall 1.839561 comb 1.830000 user 1.120000 sys 0.710000 (best of 6) With this change: ! wall 1.804222 comb 1.790000 user 1.140000 sys 0.650000 (best of 6) hg perfstatus on the same directory, without this change: ! wall 1.016609 comb 1.020000 user 0.670000 sys 0.350000 (best of 10) With this change: ! wall 0.985573 comb 0.980000 user 0.650000 sys 0.330000 (best of 10)

perf: add option to perfstatus to get the status of unknown files When status needs to look at unknown files (e.g. when running hg status), it needs to use a completely different algorithm than when it doesn't (e.g. when running hg diff).

dirstate: test normalize is truthy instead of using a no-op lambda hg perfstatus -u on a working directory with 170,000 files, without this change: ! wall 1.869404 comb 1.850000 user 1.170000 sys 0.680000 (best of 6) With this change: ! wall 1.839561 comb 1.830000 user 1.120000 sys 0.710000 (best of 6)
