contrib: update to latest Windows package versions Let's keep modern. Differential Revision: https://phab.mercurial-scm.org/D7077

rust-cpython: drop direct dependency on python(27|3)_sys We no longer use it.

rust-cpython: leverage upstreamed py_capsule_fn!() macro

rust-cpython: bump cpython crates to 0.3 Unblocks py_capsule_fn!().

rust-cpython: turn inline comments into non-doc comments

rust-cpython: fix signature of make_dirstate_tuple() Fortunately, the layout of PyObject {} is compatible with a C pointer, but we shouldn't rely on that. This also fixes the handling of NULL pointer.

rust-cpython: mark capsule function as unsafe

rust-cpython: add wrapper around decapsule_make_dirstate_tuple() There are a couple of safety issues. First, the returned function pointer must be unsafe. Second, its return value must be a raw pointer (i.e. python27_sys::PyObject), not a cpython::PyObject. The wrapper function will address these issues.

eol: don't fallback to use .hgeol from tip (BC) If no .hgeol were found in the current working directory, eol would fallback to use the one in tip. That could in some cases give very confusing or wrong behaviour when it applied wrong filters. It might be convenient to have plain 'clone' immediately apply 'native' encoding patterns in the cloned repo. But it is wrong to assume that this revision is tip, and even more wrong to also apply it when not cloning - for example when updating between history revisions. The encoding should always match the content of the current .hgeol . It should never use anything else.

eol: tweak test-eol-clone.t with better descriptions and logging Expose impact of changes coming next ...
