lib/oe/qa,insane: Move extra error handling functions to library
Extract package_qa_write_error, package_qa_handle_error and
package_qa_add_message functions from insane.bbclass to lib/oe/qa.py and
drop the package_qa_ prefixes.
Update various bbclasses to use the new functions. No import is required
since base.bbclass puts oe.qa in OE_IMPORTS.
Stop requiring callers to manually track whether a fatal error has been
encountered via a "sane" flag. Instead replace the QA_SANE variable with
QA_ERRORS_FOUND and call oe.qa.exit_if_errors or
oe.qa.exit_with_message_if_errors at the end of each task.
