We presently use the ".txt" extension for our AsciiDoc files. While not
wrong, most editors do not associate this extension with AsciiDoc,
meaning that contributors don't get automatic editor functionality that
could be useful, such as syntax highlighting and prose linting.
It is much more common to use the ".adoc" extension for AsciiDoc files,
since this helps editors automatically detect files and also allows
various forges to provide rich (HTML-like) rendering. Let's do that
here, renaming all of the files and updating the includes where
relevant. Adjust the various build scripts and makefiles to use the new
extension as well.
Note that this should not result in any user-visible changes to the
documentation.

Speed up the "lint-docs" target by making it non-.PHONY. Similar to my
c234e8a0ecf (Makefile: make the "sparse" target non-.PHONY,
2021-09-23). We'll now create empty files corresponding to a
dependency graph for each of these lint scripts.
This speeds things up a bit[1], and makes the output correspond to any
in-tree changes we have:
$ touch git-add.txt; make lint-docs; make lint-docs
GEN cmd-list.made
GEN doc.dep
LINT GITLINK git-add.txt
LINT MAN END git-add.txt
LINT MAN SEC git-add.txt
make: Nothing to be done for 'lint-docs'.
As with the "sparse" target changes this has a hard dependency on the
use of ".DELETE_ON_ERROR" in the Makefile, added here in
db10fc6c09f (doc: simplify Makefile using .DELETE_ON_ERROR,
2021-05-21). This method also depends on the output for us emitting
any errors on STDERR (fixed in a preceding commit), as well us these
scripts exiting with non-zero on any errors (which they were already
doing).

Have all of the scripts invoked by "make check-docs" emit their output
on STDERR. This does not currently matter due to the way we're
invoking them, but will in a subsequent change. It's a good idea to do
this in any case for consistency with other tools we invoke.

The lint-gitlink.perl script added in ab81411ced (ci: validate
"linkgit:" in documentation, 2016-05-04) was more complex than it
needed to be. It:
- Was using File::Find to recursively find *.txt files in
Documentation/, let's instead use the Makefile as a source of truth
for *.txt files, and pass it down to the script.
- We now don't lint linkgit:* in RelNotes/* or technical/*, which we
shouldn't have been doing in the first place anyway.
- When the doc-diff script was added in beb188e22a (add a script to
diff rendered documentation, 2018-08-06) we started sometimes having
a "git worktree" under Documentation/.
This tree contains a full checkout of git.git, as a result the
"lint" script would recurse into that, and lint any *.txt file
found in that entire repository.
In practice the only in-tree "linkgit" outside of the
Documentation/ tree is contrib/contacts/git-contacts.txt and
contrib/subtree/git-subtree.txt, so this wouldn't emit any errors
Now we instead simply trust the Makefile to give us *.txt files.
Since the Makefile also knows what sections each page should be in we
don't have to open the files ourselves and try to parse that out. As a
bonus this will also catch bugs with the section line in the files
themselves being incorrect.
The structure of the new script is mostly based on
t/check-non-portable-shell.pl. As an added bonus it will also use
pos() to print where the problems it finds are, e.g. given an issue
like:
diff --git a/Documentation/git-cherry.txt b/Documentation/git-cherry.txt
[...]
and line numbers. git-cherry therefore detects when commits have been
-"copied" by means of linkgit:git-cherry-pick[1], linkgit:git-am[1] or
-linkgit:git-rebase[1].
+"copied" by means of linkgit:git-cherry-pick[2], linkgit:git-am[3] or
+linkgit:git-rebase[4].
We'll now emit:
git-cherry.txt:20: error: git-cherry-pick[2]: wrong section (should be 1), shown with 'HERE' below:
git-cherry.txt:20: '"copied" by means of linkgit:git-cherry-pick[2]' <-- HERE
git-cherry.txt:20: error: git-am[3]: wrong section (should be 1), shown with 'HERE' below:
git-cherry.txt:20: '"copied" by means of linkgit:git-cherry-pick[2], linkgit:git-am[3]' <-- HERE
git-cherry.txt:21: error: git-rebase[4]: wrong section (should be 1), shown with 'HERE' below:
git-cherry.txt:21: 'linkgit:git-rebase[4]' <-- HERE

Amend this script added in ab81411ced (ci: validate "linkgit:" in
documentation, 2016-05-04) to pass under "use strict", and add a "use
warnings" for good measure.

It is easy to add incorrect "linkgit:<page>[<section>]" references
to our documentation suite. Catch these common classes of errors:
* Referring to Documentation/<page>.txt that does not exist.
* Referring to a <page> outside the Git suite. In general, <page>
must begin with "git".
* Listing the manual <section> incorrectly. The first line of the
Documentation/<page>.txt must end with "(<section>)".
with a new script "ci/lint-gitlink", and drive it from "make check-docs".
