formatter: add function to convert date tuple to appropriate format

journal: use fm.formatlist() to pass hashes in appropriate type (BC)

formatter: add function to convert list to appropriate format (issue5217) Before, it wasn't possible for formatter to handle array structure other than date tuple. We've discussed that at the last sprint, which ended we would probably want to allow only templatable data structure, i.e. a list of dicts: data(tags=[{'tag': a}, {'tag': b}, ...]) Unfortunately, it turned out not working well with template functions: "{ifcontains(a, tags, ...)}" ^^^^^^^^^^^^^^^^^^ "a in tags", where tags should be a plain list/set of tags So the formatter must at least know if the type [{}] was constructed from a plain list or was actually a list of dicts. This patch introduces new explicit interface to convert an array structure to an appropriate data type for the current formatter, which can be used as follows: fm.write('tags', _('tags: %s\n'), fm.formatlist(tags, name='tag')) No separate fm.data() call should be necessary.

journal: use fm.hexfunc() to get full hash in JSON/template output (BC) We generally do that.

py3: update test-check-py3-compat.t output The lower part of test-check-py3-compat.t runs only on py3 and hence its remain unchanged. Hence this patch updates the output so that change in output in the next patches will be only related to the change in the patch.

deprecation: enforce thew 'tr' argument of 'dirstate.write' (API) Compatibility was meant to be drop after 3.9 is released.

tests: remove initial bundle2 enabling in various bundle2 tests Bundle 2 is enable by default since 3.6 so we don't need this anymore. The remaining use of 'experimental.bundle2-exp' are there to test legacy behavior with bundle 1. Future patches will introduce a way outside of experimental to test that.

tests: remove bundle2 activation from test-largefiles.t This is an old config that predate bundle2 on by default. This should have been remove after Mercurail 3.6 got released.

tests: remove bundle2 activation from test-tags.t This is an old config that predate bundle2 on by default. This should have been remove after Mercurail 3.6 got released.

templatekw: change joinfmt to a mandatory argument of _hybrid object We've fixed several bugs caused by the misuse of the default joinfmt. Make it more explicit to prevent future bugs. dict.values()[0] is replaced by dict[element] as showlist() knows what the key is.

url: drop compatibility wrapper of socket.create_connection() It should be available on Python 2.6+.

doc: remove double imports of inspect from hgmanpage.py

merge: concatenate default conflict marker at parsing phase of .py "+" operations are unnecessary.

tests: remove bundle2 activation from test-push-warn.t This is an old config that predate bundle2 on by default. This should have been remove after Mercurail 3.6 got released.
