largefiles: fold oddly named _verify into remotestore.exists

git convert: some versions of git use fatal: instead of error: I saw this behavior with git 1.7.12 on my Mac.

test-convert-git: stabilize corruption of test git repo This error would show up only intermittently since the test depended on the order of the directories returned by os.walk. The damage repository test would delete the first object file it came across. However, the order of the directory listing is arbitrary (it seems to depend on the filesystem). This meant that sometimes a commit object was deleted, sometimes a blob object and sometimes a tree object. So, fix by hardcoding which object to delete. Delete a commit object, a blob object and a tree object in three separate tests.

convert/git: catch errors from modern git-ls-remote (issue3428) Since git v1.7.8.2-327-g926f1dd (the change was first released in git 1.7.10), git does not return non-zero when "git ls-remote --tags ..." is run and the repository is damaged. This causes the "damaged repository with missing commit" test in test-convert-git.t to unexpectedly succeed. Fix by aborting if git outputs any lines beginning with "error:", which required adding some subprocess use in convert/git.py.

incoming: fix incoming when a local head is remotely filtered (issue3805) In its current state discovery may return (remotely) filtered elements in "common". This has usually no impact as "missing" is kept clear of filtered elements. However when the "remote" repo is a local repo (disk accessible, and directly created in memory) the incoming code takes a shortcut and directly uses the "remote" repo to generate the incoming output. When some common elements are filtered this led to a crash. We now ensure we use an unfiltered repository to generate the incoming output. This does not change the behavior as missing is clear of filtered revision. Now that we have proper low level filtering, incoming code needs a deeper cleanup but it is already planned.

dirstate: move pure python dirstate packing to pure/parsers.py

bookmark: don't allow integers as bookmark/branch/tag names Bookmarks/branches/tags shouldn't be allowed to be integers because that overlaps with revision numbers. Right now if a user created one they can't use it anyway because the revision numbers take precedence. The check only happens when creating a new bookmark/etc from a command so it shouldn't affect existing bookmarks/branches/tags or importing branches from git. This fix was prompted by us having a user create a bookmark named "404" then accidentally checkout a very old version of our repository.

run-tests: do not fail on empty tsttest file Initialize n for not failing on empty tsttest files.
