[bitbake-devel] [PATCH 12/16] runqueue: Clean up BB_HASHCHECK_FUNCTION API

[Richard Purdie]

This function uses an old API which uses offsets into lists as a communication
mechanism. Update the API to use "tid" which is used universally in runqueue now.

We can also add kwargs support to the funciton definition to drop some of the
backwards compaiblility hoops we had to jump though with different function
argument combinations.
