Richard Purdie 9043034da5 bitbake: cooker: Rework the parsing results submission
The loop submitting the parser results was not efficient on many core systems
as may of the parsers could block for a long time waiting to send the results.
While a result was pending, the code wouldn't parse further jobs.

Change the code to parse further jobs even if the results can't be submitted
and lower the result submission timeout to keep the parsers busy.

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
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

Mailing list:

    https://lists.openembedded.org/g/bitbake-devel

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. Git must be correctly configured, in
particular the user.email and user.name values must be set.

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
