Take the pm_ptr() macro as example:
⟩ ctags -x --kinds-c=+p+x --extras='-{anonymous}' include/linux/pm.h | grep pm_ptr
pm_ptr macro 475 include/linux/pm.h #define pm_ptr(_ptr) PTR_IF(IS_ENABLED(CONFIG_PM), (_ptr))
The previous grep would remove the pm_ptr() line because it contains
CONFIG_. We only want to remove a line if it starts with CONFIG_.

Falcon requires field names on one level to be the same on all

This changes the stdout/stderr buffering behavior of Python. Without it,
indexing scripts don't stream updates and use really big buffers.

Instead, start from $0 and move back up two times. So, something like:
./elixir/utils/index
./elixir/utils
./elixir
./elixir/update.py

Stop writing a global file when initializing projects. This can cause
permission issues. We instead pass the option manually for each Git
process call using:
git -c safe.directory=...

Previously, to start an indexing from scratch:
./utils/index /srv/elixir-data musl https://git.musl-libc.org/git/musl
This is annoying as the script already has the remote URLs for all known
projects. Now, a call without remote will automatically add the remote
URLs matching the project name:
./utils/index /srv/elixir-data musl
This copies the behavior that was previously only implemented for --all.

New script utils/index does an automatic call to `git gc --auto` and if
it detects a gc.log file, it runs `git gc --aggressive`.
There shouldn't be any reason for people to have to think about that
aspect. Remove that info from the README and make it lighter weight.

utils/pack-repositories did the following on repos which have a gc.log
file existing (created when GC fails):
git prune
git gc --aggressive
git prune
git gc --aggressive
Here we:
- Delete utils/pack-repositories; we don't want that detection to be
done manually. Instead, we integrate the gc.log detection into
utils/index that should be called often.
- Create a hidden flag ($ELIXIR_GC) to allow manual trigger.
- Replace the above sequence with a simpler `git gc --aggressive`.
Let's trust Git.
- Do a `git gc --auto` in the default case. This call is automatically
done by porcelain commands but we don't run any so let's give Git an
opportunity to cleanup from time to time (heuristic based).
- Replace the gc.log detection from:
find . -name gc.log
To:
test -e $data/$project/repo/gc.log
It should be more reliable. With the first approach we risk projects
that contain a file gc.log to trigger the detection on each run.

Avoid the following Git warning:
hint: Using 'master' as the name for the initial branch. This default branch name
hint: is subject to change. To configure the initial branch name to use in all
hint: of your new repositories, which will suppress this warning, call:
hint:
hint: git config --global init.defaultBranch <name>
hint:
hint: Names commonly chosen instead of 'master' are 'main', 'trunk' and
hint: 'development'. The just-created branch can be renamed via this command:
hint:
hint: git branch -m <name>

Previously:
LXR_PROJ_DIR=/srv/elixir-data ./utils/update-elixir-data
Now:
./utils/index /srv/elixir-data --all
The impact is slightly different: it also has the side-effect of
creating all known projects (Linux, U-Boot, etc.) if they didn't exist.
We have asked around and we are not aware of any other Elixir instance.
To keep the previous behavior, if people don't want to index all
supported projects:
x=/srv/elixir-data
find $x -mindepth 1 -maxdepth 1 -printf "%f\n | \
xargs -L1 -r ./utils/index $x

Allow calling like:
./utils/index musl
That will do the same thing as before (fetch+index).
It works only if a previous call was made to add remotes.
