This is experimental and probably will break some platforms

Split implementation of several command line options from
options_init_from_torrc into smaller isolated functions.

Previously it just used /usr/bin/env/python, which would fail if we
only had a "python3" binary.

Fixes bug 40095; bugfix on 0.4.4.1-alpha.

Eventually this should be used by every one of our CI scripts.

Also adds the compiled and running glibc version when using the
--library-versions flag.

This differs from my old git-resquash.sh in that it uses the newer
`git rebase --keep-base` if available

Our old https://bugs.torproject.org/nnnn URLs only work for bugs
numbered before 40000.  Newer gitlab bugs need to have specific
projects mentioned.

This patch assumes that bugs are in tpo/core/tor by default, but
allows us to refer to several other projects by saying
e.g. "chutney#40002" if we want.

Also adds generic tor_glob function to expand globs.

Closes #40044

The osx version of this tool doesn't have --backup

Analogously to tor-github, we now make a tor-gitlab repository.  It
is set up to disable push direct attempts, and to fetch merge
requests into appropriate branches.

git-pull-all.sh knows how to fetch this repository.

LTTng tracepoint probe declaration is not really following a C standard that
coccinelle and checkSpace.pl likes.

Move everything to a .inc file and standardize the trace_probes_circuit.h
header to include that LTTng specific file if the instrumentation was enabled
at configure time.

This is the very first tracepoint in tor. It is in the circuit subsystem for
when a new circuit opens.

LTTng instrumentation requires lot more around a tracepoint than USDT thus
this commit only adds one tracepoint in order to outline a base to add more
tracepoints later.

The idea is that we separate subsystem into what LTTng defines as "providers"
so the circuit provider contains the tracepoint definitions for the circuit
subsystem.

We introduce TOR_EXTRA_PRE_COMMIT_CHECKS environment variable to run the
pre-commit hook. The pre-push git hook will set it in order to run all
pre-commit checks.

Only warn when we actually want a commit _and_ there are uncommitted changes
found. Else, it is fine to rename if the script is not creating a commit.

Faster Than Light!

Previously, this script ran over every C file in our source code,
which took up to a minute on my desktop.

Instead, the script now has several modes that it can run in, to
minimize the time spent and improve useful output.  It should now be
suitable for everyday use and git hooks.  I hope.

I've also renamed this script, so that we can keep using it in the
future if we were to move to some tool other than clang-format.

Per <https://trac.torproject.org/projects/tor/ticket/34381>, these
contrib scripts were generated by older versions of Tor and shellcheck
will throw warnings if they still exist.

Accept extra lines in nodelist and routerlist due to extra features, and
due to refactors that simplify some functions.

Most of the refactor eliminated duplicate code in smaller functions, so
there's only one large function that got smaller.
