Allow the user to specify relative or absolute or any other funky
path that they want when using `repo init` or `repo sync`. Our
goal is to restrict the paths in the remote manifest git repo we
cloned from the network, not protect the user from themselves.

With the recent commit 0501b29e7a
("status: Use multiprocessing for `repo status -j<num>` instead of
threading"), the limitation with project serialization no longer
applies. It turns out that ad-hoc logic is expensive. In the CrOS
checkout (~1000 projects w/8 jobs by default), it adds about ~7sec
overhead to all invocations. With a fast nop run:
time repo forall -j8 -c true
This goes from ~11sec to ~4sec -- more than 50% speedup.

If a manifest checksout a project multiple times, repo download isn't
able to accurately pick the right project. We were just picking the
first result which could be a bit random for the user. If we hit that
situation, check if the cwd is one of the projects, and if it isn't,
we emit an error and tell the user it's an ambiguous request.

The clone bundle logic assumes there is a one-to-one mapping between the
projects/ and project-objects/ trees. When using shared projects (where
we checkout different branches from the same project), this would lead us
to fetching the same clone bundle multiple times. Automatically skip the
clone bundle logic if the project-objects/ dir already exists.

On macOS, the Finder app likes to poop .DS_Store files in every path
that the user browses. If the user pokes around the .git/ tree, it
could generate a .DS_Store file in there too. When repo goes to read
all the local refs, it tries to decode this binary file as UTF-8 and
subsequently crashes.
Since paths that begin with . are not valid refs, ignore them like we
already do with paths that end in .lock. Also bump the check up to
ignore dirs that match since that follows the git rules: they apply
to any component in its path, not just the final path (name).
We don't implement the full valid ref algorithm that git employs as
it's a bit complicated, and we only really need to focus on what will
practically show up locally.

Generalize the logic & function arguments slightly so we can reuse
in more places that make sense.
This changes the validation logic slightly too in that we no longer
allow "." for the dest attribute with copyfile & linkfile, nor for
the src attribute with copyfile. We already rejected those later on
when checking against the active filesystem, but now we reject them
a little sooner when parsing.
The empty path check isn't a new requirement exactly -- repo used to
crash on it, so it was effectively blocked, but now we diagnosis it.

The idea for skipping some progress updates was to avoid spending
too much time on the progress bar itself. Unfortunately, for large
projects (100s if not 1000s) of repos, we get into the situation
with large/slow checkouts that we skip showing updates when a repo
finishes, but not enough repos finished to increase the percent.
Since the progress bar should be relatively fast compared to the
actual network & local dick operations, have it show an update
whenever the caller requests it. A test with ~1000 repos shows
that the progress bar in total adds <100ms.

Added --no-use-superproject to repo and init.py to disable use of
manifest superprojects.
Replaced the term "sha" with "commit id".
Added _GetBranch method to Superproject object.
Moved shared code between init and sync into SyncSuperproject function.
This function either does git clone or git fetch. If git fetch fails
it does git clone.
Changed Superproject constructor to accept manifest, repodir and branch
to avoid passing them to multiple functions as argument.
Changed functions that were raising exceptions to return either True
or False.
Saved the --use-superproject option in config as repo.superproject.
Updated internal-fs-layout.md document.
Updated the tests to work with the new API changes in Superproject.
Performance for the first time sync has improved from 20 minutes to
around 15 minutes.
Tested the code with the following commands.
$ ./run_tests -v
Tested the sync code by using repo_dev alias and pointing to this CL.
$ repo init took around 20 seconds longer because of cloning of superproject.
$ time repo_dev init -u sso://android.git.corp.google.com/platform/manifest -b master --partial-clone --clone-filter=blob:limit=10M --repo-rev=main --use-superproject
...
real 0m35.919s
user 0m21.947s
sys 0m8.977s
First run
$ time repo sync --use-superproject
...
real 16m41.982s
user 100m6.916s
sys 19m18.753s
No difference in repo sync time after the first run.

We have access to repodir on the command object itself, so we don't
need to pull it indirectly out of the manifest object.

A little sugar simplifies the code a bit.

Changed "git pull" to "git fetch" as we are using --bare option. Used the
following command to fetch:
git fetch origin +refs/heads/*:refs/heads/* --prune
Pass --branch argument to Superproject's UpdateProjectsRevisionId function.
Returned False/None when directories don't exist instead of raise
GitError exception from _Fetch and _LsTree functions. The caller of Fetch
does Clone if Fetch fails.
Tested the code with the following commands.
$ ./run_tests -v
Tested the init and sync code by copying all the repo changes into my Android
AOSP checkout and running repo sync with --use-superproject option.

After updating all project’s revsionIds with the SHAs from superproject,
write the updated manifest into superproject_override.xml file. Reload
that file for future Reloads. This file is created in exp-superproject
directory.
Moved most of the code that is superproject specific into
git_superproject.py and wrote test code.
If git pull fails, did a git clone of the superproject.
We saw performance gains for consecutive repo sync's. The time to sync
went down from around 120 secs to 40 secs when repo sync is executed
consecutively.
Tested the code with the following commands.
$ ./run_tests -v tests/test_git_superproject.py
$ ./run_tests -v
Tested the sync code by copying all the repo changes into my Android
AOSP checkout and doing a repo sync --use-superproject twice.
First run
$ time repo sync --use-superproject
