Philip Lorenz b3e316e848 bitbake: fetch2: Ensure that git LFS objects are available
The current implementation only performs a git lfs fetch alongside of a
regular git fetch. This causes issues when the downloaded revision is
already part of the fetched repository (e.g. because of moving back in
history or the updated revision already being part of the repository at
the time of the initial clone).

Fix this by explicitly checking whether the required LFS objects are
available in the downloade directory before confirming that a downloaded
repository is up-to-date.

This issue previously went unnoticed as git lfs would silently fetch the
missing objects during the `unpack` task. With network isolation turned
on, this no longer works, and unpacking fails.

(cherry picked from commit cfae1556bf671acec119a6c8bbc4b667a856b9ae)

Bitbake
=======

BitBake is a generic task execution engine that allows shell and Python tasks to be run
efficiently and in parallel while working within complex inter-task dependency constraints.
One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software
stacks using a task-oriented approach.

For information about Bitbake, see the OpenEmbedded website:
    https://www.openembedded.org/

Bitbake plain documentation can be found under the doc directory or its integrated
html version at the Yocto Project website:
    https://docs.yoctoproject.org

Contributing
------------

Please refer to
https://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded
for guidelines on how to submit patches, just note that the latter documentation is intended
for OpenEmbedded (and its core) not bitbake patches (bitbake-devel@lists.openembedded.org)
but in general main guidelines apply. Once the commit(s) have been created, the way to send
the patch is through git-send-email. For example, to send the last commit (HEAD) on current
branch, type:

    git send-email -M -1 --to bitbake-devel@lists.openembedded.org

Testing:

Bitbake has a testsuite located in lib/bb/tests/ whichs aim to try and prevent regressions.
You can run this with "bitbake-selftest". In particular the fetcher is well covered since
it has so many corner cases. The datastore has many tests too. Testing with the testsuite is
recommended before submitting patches, particularly to the fetcher and datastore. We also
appreciate new test cases and may require them for more obscure issues.
