Allow repo lock to be passed in to localrepo.commit for performance

Automatic nesting into running transactions in the same repository. This associates a transaction handle with a given repository object, and any additional calls to start new transactions reuse that transaction. For the 2700 patch import run, this brings the system time down from 1m20s to 50s, mostly by skipping backups of the dirstate file. (note, this patch does not change hg import to use the nested transaction, mq is the only user right now)

Fix bash_completion on Solaris TK Soh noticed that the awk that ships with Solaris doesn't allow you to define new functions. According to http://www.shelldorado.com/articles/awkcompat.html it looks like it also doesn't have some other stuff that we were using, like deletion of an array element and gsub. Rewrite the parsing of hg --debug help to work around that. This version doesn't filter aliases that are simple abbreviations for debug commands (not a big problem, since there are none right now).

refactor the dodiff optimization

speed up hg log --patch Changing dodiff to read the manifest/changelog for node1 before calling repo.update allows us to take advantage of the revlog revision cache. Before this patch and my previous "speed up hg log --debug" patch, when using hg log -p to display three revisions (A, B and C), dodiff and repo.changes would end up reading the manifests in this order: B A B A C B C B With both patches, this order becomes: A A B B B B C C (This considers only dodiff and repo.changes. I'm not sure how other parts of hg log enter the picture.) The speed up will depend on the revisions being displayed. (All "before" times already have my previous "speed up hg log --debug" patch applied.) hg repo (tip = 414e81ae971f). hg log -p before after real 0m50.981s 0m45.279s user 0m47.930s 0m42.560s sys 0m2.526s 0m2.523s output size: 6917897 bytes kernel repo (tip = 9d4e135960ed). hg log -p -l64 before after real 2m14.995s 1m45.025s user 2m9.509s 1m33.900s sys 0m3.663s 0m2.942s output size: 31497621 bytes same kernel repo. hg log -p -l64 -r c84c2069592f:0 before after real 1m48.045s 1m0.076s user 1m44.094s 0m58.492s sys 0m2.603s 0m1.103s output size: 197983 bytes c84c2069592f was the tip of a 10 day old kernel repo that I had lying around and was where I first tested this patch. For some weird coincidence it's also a place where the patch makes a huge difference.

speed up hg log --debug hg repo: before: real 0m6.998s user 0m6.952s sys 0m0.046s after: real 0m3.884s user 0m3.839s sys 0m0.042s

on revert, only undele files that are removed in the dirstate

Removed now obsolete min/max check in walkchangerevs().

Replaced fixed window size for walkchangerevs with an increasing one. Window sizes starts at 8 (for good interactiveness) and doubles with each window until it is 512, which seems to be the maximum efficient value.

hgmerge: do not use file with markers in tools merging themselves This time I forgot about a crucial part of the logic change. The patch makes kdiff3 and tkdiff useful again.
