[bitbake-devel] [PATCH v3] bitbake/lib/bb/cookerdata.py: Improve response when bitbake-layers can't find layer conf file

[Humberto Ibarra]

If an invalid layer is added to bblayers.conf, the parsing of said file
ends with a trace and an "Unable to parse" exception. This is not the
ideal output, especially considering that we know exactly why this is failing.

This patch handles this situation failing with a graceful error message. The
message shows the path to the conf file that couldn't be found.

[Yocto #9506]
