merge.applyupdates: only attempt to merge files in mergeactions This only makes a difference when a merge driver is active -- in that case we don't want to try and merge all the files, just the ones still unresolved after the merge driver's preprocess step is over.

filemerge: rename _symlinkcheck to _mergecheck We're going to be adding other checks in here soon.

test-merge-prompt.t: rename to test-merge-changedelete.t Because: (a) the only prompts we test in this file are change/delete prompts, and (b) we're going to be expanding the scope of this test to cover future improvements to change/delete conflicts, including avoiding prompts altogether.

tags: create new sortdict for performance reasons sortdict internally maintains a list of keys in insertion order. When a key is replaced via __setitem__, we .remove() from this list. This involves a linear scan and array adjustment. This is an expensive operation. The tags reading code was calling into sortdict.__setitem__ for each tag in a read .hgtags revision. For repositories with thousands of tags or thousands of .hgtags revisions, the overhead from list.remove() noticeable. This patch creates a new sortdict() so __setitem__ calls don't incur a list.remove. This doesn't appear to have any performance impact on my Firefox repository. But that's only because tags reading doesn't show up in profiles to begin with. I'm still waiting to hear from a user with over 10,000 tags and hundreds of heads on the impact of this patch.

largefiles: specify where .orig files are kept This patch let's the user specify where .orig files are kept using the cmdutil.origpath function

mq: let the user choose where .orig files are kept This patch uses cmdutil.origpath to let the user decide where .orig files are kept when backup files are created.

shelve: choose where .orig file locations are kept This patch uses cmdutil.origpath to let the user set the location of the orig files.

filemerge: choose where .orig files are kept Having .orig files litter your working copy is a common complaint. This patch uses cmdutil.orig to let the user determine where those files should reside.

git-subrepos: revert respects specified location to save .orig files This patch makes revert in git subrepos save .orig files where the user wants them by using the cmdutil.origpath function.
