obsolete: remove two unused constants I'm not sure what these constants were intended for, but they have no users so it's time to say goodbye. Differential Revision: https://phab.mercurial-scm.org/D12609

node: manually implement Debug I got too irritated today with the default Debug implementation of hg::revlog::Node while playing with a new parser. This isn't quite what I wanted, but it wasn't much code and it at least gives you output that's easy to visually compare to a node.hex()ed identifier from the Python side of things. Sadly, this doesn't influence the output in lldb or the VSCode debugger extension that uses lldb under the covers, but it at least means debug prints are a little more useful.

censor: make rhg fall back to python when encountering a censored node This is to make it support censor.policy=ignore without having to duplicate that logic. Also, change the censor test in such a way that it uses rhg now, because extensions are disabled except when we call [hg censor]. Differential Revision: https://phab.mercurial-scm.org/D12607

contrib: migrate off of a couple of bitbucket URLs I noticed this when diffing the thg installer against Mercurial to see what was missing. There are a handful of other URLs in i18n and extension example help text if anyone cares to update those. Differential Revision: https://phab.mercurial-scm.org/D12606

diff: add help text to highlight the ability to do "merge diffs" Differential Revision: https://phab.mercurial-scm.org/D12605

followlines: don't put Unicode directly into the .js file (issue6559) Apparently some web server setups may serve this file in a different encoding than UTF-8, and that results in visual garbage in the followlines button that renders for every line in a file. So instead of using this Unicode character in UTF-8 we can encode it as \u2212. Or, to be more explicit, we can use − HTML entity, which resolves into exactly that character. Since now we're using innerHTML property to set the minus part of the button, let's use it to set the plus part as well (even though the plus sign was plain ASCII). A wise man once said "A foolish consistency is the hobgob... eh, whatever." Throw a brick at me if this makes things worse. Differential Revision: https://phab.mercurial-scm.org/D12597

wix: bump the minimum Windows required to 8.1 PyOxidizer binaries are built with py 3.9.6, so not even Windows 7 is supported. Unfortunately, there don't appear to be more recent values for newer versions of Windows, but at least Windows 8.1 is still in extended support for another 9 months or so.
