largefiles: add precommit hook to check for inappropriate locking This tests for inappropriate locking (issue3182) by running hg status as a precommit hook.

largefiles: fix inappropriate locking (issue3182) Don't lock/write on operations that should be readonly (status). Always lock when writing the lfdirstate (rollback). Don't write lfdirstate until after committing; state isn't actually changed until the commit is complete.

largefiles: correctly handle dirstate status when rebasing When rebasing, we need to trust that the standins are always correct. The rebase operation updates the standins according to the changeset it is rebasing. We need to make the largefiles in the working copy match. If we don't make them match, then they get accidentally reverted, either during the rebase or during the next commit after the rebase. This worked previously only becuase we were relying on the behavior that largefiles with a changed standin, but unchanged contents, never showed up in the list of modified largefiles. Unfortunately, pre-commit hooks can get an incorrect status this way, and it also results in extra execution of code. The solution is to simply trust the standins when we are about to commit a rebased changeset, and politely ask updatelfiles() to pull the new contents down. In this case, updatelfiles() will also mark any files it has pulled down as dirty in the lfdirstate so that pre-commit hooks will get correct status output.

largefiles: implement addremove (issue3064) Implementing addremove correctly in largefiles is tricky, becuase the original addremove function does not call into any of the add or remove function we've already overridden in the extension. So the trick is to implement addremove without duplicating any code. This patch implements addremove by pulling out the interesting parts of override_add() and override_remove() into generic utility functions, and using those to handle the largefiles in addremove. Then a matcher is installed that will ignore all largefiles, and the original addremove function is called to take care of the regular files in addremove. A small bit of monkey patching is used to make sure that remove_largefiles() notifies the user when a file is removed by addremove and also makes sure the removal of largefiles doesn't interfer with the original addremove's operation of removing the standin.

Use explicit integer division Found by running the test suite with the -3 flag to show places where we have int / int division that can be replaced with int // int.

largefiles: fix confusion upon removal of added largefile (issue3176) This patch makes "hg remove" work the same way on largefiles as it does on regular Mercurial files. If you try to remove an added largefile, the removal fails and you are instead prompted to use "hg forget" to undo the add.
