This adds support for the new bitbake-setup:
* Maintain backwards compatibility for poky-classic releases
* Assume bitbake-setup for all releases 'master' and forward
* When no ".templateconf" assume Poky and not OE
* Generate and use "init-build-env" script instead of 'oe-init-build-env'
directly, but "cd" to the clone and not the local installation.
* Include "bblayers.conf" because "cookerdata.py" now explicitly
required it, and let it be over-ridden by the usual "toaster-bblayers.conf".
* Force the value "TOPDIR" in "toaster.conf" to the local project's directory.
Normally "cookerdata.py" sets TOPDIR from getcwd(), but somehow in bitbake-setup
mode the CWD at this point has become ".../layers/openembedded-core", so
"bitbake.conf and all other files cannot be found. This non-obvious problem was
hard to discover. Until this is understood, the forced value will make things work.

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
Bitbake requires Python version 3.8 or newer.
Contributing
Please refer to our contributor guide here: https://docs.yoctoproject.org/contributor-guide/ for full details on how to submit changes.
As a quick guide, patches should be sent to bitbake-devel@lists.openembedded.org The git command to do that would be:
git send-email -M -1 --to bitbake-devel@lists.openembedded.org
If you're sending a patch related to the BitBake manual, make sure you copy the Yocto Project documentation mailing list:
git send-email -M -1 --to bitbake-devel@lists.openembedded.org --cc docs@lists.yoctoproject.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.
To run the tests "zstd" and "git" must be installed.
The assumption is made that this testsuite is run from an initialized OpenEmbedded build
environment (i.e. source oe-init-build-env is used). If this is not the case, run the
testsuite as follows:
export PATH=$(pwd)/bin:$PATH
bin/bitbake-selftest
The testsuite can alternatively be executed using pytest, e.g. obtained from PyPI (in this case, the PATH is configured automatically):
pytest
