setup: remove more Python 2 support code I'll inline print() etc in future patches. Differential Revision: https://phab.mercurial-scm.org/D12270

setup: remove ssl check that only matters on 2.7 Differential Revision: https://phab.mercurial-scm.org/D12269

setup: remove block that tries to help Python 2.6 users It's time to move on folks. Differential Revision: https://phab.mercurial-scm.org/D12268

setup: drop statement of support for Python before 3.5.3 🎉🎉 Differential Revision: https://phab.mercurial-scm.org/D12266

cext: remove inline rewriting of argv This only worked on Python 2. And since we dropped support for Python 2, we can drop support for this functionality. Differential Revision: https://phab.mercurial-scm.org/D12233

cext: remove PY23() Since we always run on Python 3 now, we no longer need this macro to support Python 2. We refactor all users to just use the 2nd argument. Differential Revision: https://phab.mercurial-scm.org/D12232

cext: unconditionalize PySlice_GetIndicesEx() We only support Python 3 now. Differential Revision: https://phab.mercurial-scm.org/D12231

cext: unconditionalize PYLONG_VALUE() We only support Python 3 now. Differential Revision: https://phab.mercurial-scm.org/D12230

cext: use PyLong symbols We no longer support Python 2. So we can unconditionally use the Python 3 symbol names. Differential Revision: https://phab.mercurial-scm.org/D12229

cext: use PyLong symbols We no longer need to support Python 2. So use the Python 3 symbol names directly. Differential Revision: https://phab.mercurial-scm.org/D12228

cext: remove Python 2 support We still alias the Python 2 symbols. This will be cleaned up in a separate commit. Differential Revision: https://phab.mercurial-scm.org/D12227

cext: remove Python 2 file handling code Differential Revision: https://phab.mercurial-scm.org/D12226

cext: remove Python 2 variant of listdir_slot() Differential Revision: https://phab.mercurial-scm.org/D12225

cext: remove some conditional preprocessor defines We may want to inline these defines. But for now, getting rid of the Python 2 support is a step forward. Differential Revision: https://phab.mercurial-scm.org/D12224

cext: unconditionally use PyLong_FromLong() We no longer support Python 2. Differential Revision: https://phab.mercurial-scm.org/D12223

cext: drop preprocessor PyInt aliases Now that we dropped support for Python 2 we can use the Python 3 native functions. Differential Revision: https://phab.mercurial-scm.org/D12222

cext: remove Python 2 module initializer functions We no longer need these since we dropped support for Python 2. Differential Revision: https://phab.mercurial-scm.org/D12221

rhg: simplify the handling of share-safe config mismatch Differential Revision: https://phab.mercurial-scm.org/D12213

branching: merge stable into default

heptapod-ci: remove Python 2 support (hurray!) 6.1 was the last release to support Python 2, let's lighten the CI. Differential Revision: https://phab.mercurial-scm.org/D12206

relnotes: add 6.1.3 and 6.1.4

Added signature for changeset 0cc5f74ff7f0

Added tag 6.1.4 for changeset 0cc5f74ff7f0

purge: prevent a silly crash with --confirm --files if --files is passed, there was no directory to checks and `msg` was undefined. This is now fixed and tested.

rust-status: don't trigger dirstate v1 rewrite when only v2 data is changed The assumption that we need to rewrite (or append to) the dirstate if the ignore pattern hash has changed or if any cached directory mtimes have changed is only valid when using dirstate-v2. In dirstate-v1, neither of these things are written to disk.

commit: allow to close branch when committing change over a closed head Otherwise, an explicit other commit become necessary, which seems both silly and verbose. This is useful when merging closed heads on the same branches, for example when merging multiple repositories together.

logcmdutil: use the same data as {file*} template keywords (issue6642) Since 0c72eddb4be5 template keywords that show files use a different source of data than ctx.p1().status(ctx). These two functions in logcmdutil also show file lists when needed (e.g. log with --debug flag), but previously they used the old way of just looking at status compared to p1 and it resulted in differences between e.g. hg log --debug and hg log -T '{file*}'. test-phases.t needs an adjustment because 7 is a merge commit of two topological branches and one of them introduces files C, D and E.

tests: show that hg log --debug output differs from {file*} template keywords hg log --debug -T xml doesn't differ, but let's test it because we can.
