test: remove dangling --config in test-metaedit.t

tests: fix previously accidentally matching regexes in test-touch.t Before Mercurial commit 6d5718e39657 (run-tests: make "| foo (re)" not match everything, 2017-11-29), regexes like "| foo", which are common in graphlog output, would incorrectly match anything. After that commit, they match as they should, meaning that either "" or " foo" would match, but not a "| foo". This commit fixes the test by replacing the "|" by "." rather than escaping with "\|" since that would make the graph harder to read.

test: update test-discovery-obshashrange.t

test: remove dangling --config in test-metaedit.t

serverminitopic: also avoid reading Avoiding to write cache for filter where topic applies is a good step, but we need to also avoid reading it. Existing branchmap cache might exists before the turned the feature on.

topic: introduce a minimal extensions to enable topic on the server This small extensions simply expose topic in the branch. This should help getting minimal support for topic from various hosting solution (eg: bitbucket maybe ?) See extensions help for details.

branching: merge stable into default

pusoperation: wrap pushoperation __init__ directly This is how remote names does it. Using the same method should helps with compatibility when mixing the two extensions.
