commands: move metaedit to the 'evocommands' module

rewriteutil: move the 'rewrite' function

rewriteutil: move 'foldcheck' to the new module

rewriteutil: move disallowednewunstable in the new module

rewriteutil: create a rewriteutil module to host utility function The ultimate goal of this module is to gather basic building block for rewriting changesets. This is aimed at moving into core and being use by the core extension.

interactive: fix the interractive option import The move made in e6bc6eaa17c5 was buggy.

test: update test output to match b11e8c67fb0f hg debugobsolete now issues a message about the obsoleted changesets.

test: update test output from b47fef6d2365 We run this check for bundle1 too now.

compat: add a compatibility layer for bookmark move The API was updated in 4.3 (712a85b3677f) we adapt to that.

compat: use 'safehasattr' over 'hasattr' 'hasattr' is broken in python 2.

stack: show short node of changesets in `hg stack -v` After this patch, hg stack -v shows short nodes for changesets which have topic index, i.e. excluding the bases except t0.

compat: use 'repo.cachevfs' when available In 4133c0b0fcd7 (core), the repository gained a new vfs dedicated to caches. We update the code to follow this new pattern.

debugobsconvert: take the lock when writing the obsstore file We were upgrading the store unprotected.

topics: add a test demonstarting sorting of topics by time using --age

branching: merge with stable

prev: allow to update to 't0' from 't1' When on the first changeset of a topic, one can move back one changeset to end up on t0. The new working copy parent to not belong to the topic, but the topic is still active. The next commit will create a new root to the active topic. You can get the same result using `hg up t0`

topic: add a 'topicidx()' to context This will be useful for the `t0` logic in `hg prev`

prev: retrieve the 'no-topic' result is a clear and reusable option We'll use it more, so let us make it pretty first.

prev: add '_getcurrenttopic' helper and use it We'll add more spot where this information is used.

prev: explicitly use 'p1' as a variable name This make the code clearer.

topic: rename the internal topic option we'll use it more widely so I give it a more generic name. It is an internal option so not wories regarding compatibility.

prev: extract the code computing the destination This make the handling of the result simpler. The test agree as one return code is fixed.

prev: issue a proper error when reaching repository root (and adds the associated test)

prev: stop creating a repository at the root of 'test-repo.t' We run the test in a subdirectory now, this usually avoid various kind of future issue.

prev: extract the function performing the update That code is fairly independant so let us isolate it to simplify the rest of the code.

prev: simplify the bookmark preserving logic We can use 'None' as a special value and have a simpler code.

prev: rename 'p' to 'target' This makes the code clearer.

topics: check for topic on commit before a user enters message We have a enforce-topic cofig which can forbid user to commit without a topic on it. We used to check topic on a commit after the user enters message, but we should fail early.

packaging: update readme I forgot again.

topics: add a new flag --age which will show last touched time for topics This adds a new flag `--age` to `hg topic` command which will show topics sorted by their last touched time and will also show the last touched time for them. This patch also adds a simple test to make sure the flag does not breaks by future changes. Adding more tests showing output like "3 hours ago", "2 minutes ago" etc will change as the code takes time.time() into account which will increase with time, and hence the output will change, so we need some static output like a date.

uncommit: expose the feature with a '--extract' to amend The name of the "uncommit" feature have been an ongoing issue, but no better name have been found in the past year. We try another approach by exposing the 'uncommit' feature directly in `hg amend`. The command will not be able to do both operation a the same time (add new change to the commit + extract should change, but this is already the case with the two command today.

uncommit: add support for -U and -D
