run-tests: extract onStart and onEnd into the test result It would allow custom test result to display custom messages. Differential Revision: https://phab.mercurial-scm.org/D3701

run-tests: add support for external test result The goal is to begin experiment with custom test result. I'm not sure we should offers any backward-compatibility guarantee on that plugin API as it doesn't change often and shouldn't have too much clients.

encoding: alias cp65001 to utf-8 on Windows As far as I can tell, cp65001 is the Windows name for UTF-8. I don't know how different it is from the UTF-8, but Python 3 appears to have introduced new codec for cp65001, so the alias is enabled only for Python 2. https://bugs.python.org/issue13216 This patch is untested, but hopefully fixes the following issue. https://bitbucket.org/tortoisehg/thg/issues/5127/

remotenames: synchronise remotenames after push also Earlier we use to pull remotenames information from the server in case of pull and clone only. This patch adds logic to push also command to pull remotenames information. This will help us in keeping the remotenames more upto date where there are a lot people changing state of branches and bookmarks at the server.

fileset: pass in badfn to inner matchers Just for sanity. No idea if this will make a difference, but it should propagate the badfn because the matcher created by mctx.matcher() will be returned by fileset.match() in future patches.

fileset: restrict getfileset() to not return a computed set (API) And rename the functions accordingly. fileset.match() will be changed to not compute the initial subset. test-glog*.t get back to the state before 9f9ffe5f687c "match: compose 'set:' pattern as matcher."

match: add prefixdirmatcher to adapt subrepo matcher back This serves as an inverse function to the subdirmatcher, and will be used to wrap a fileset matcher of subrepositories. One of the root/prefix paths could be deduced from the matcher attributes to be wrapped, but we don't since the callers of this class know the root/prefix paths and can simply pass them in.

fileset: make debugfileset filter repository files This prepares for the structural change of the fileset. A computed fileset will no longer be a set of files, but a boolean function (i.e. matcher) to test if an input file matches the given fileset expression. --all-files option is added because some examples in the test need to scan files across revisions.

bundle2: use ProgrammingError to report bad use of addparam() This allows us to embed error message in bytes.
