mesa: Merge handling of application-provided and built-in error sources.

I want to have dynamic IDs so that we don't need to add to mtypes.h for
every error we might want to add.  To do so, I need to get rid of the
static arrays and actually support all the crazy filtering of dynamic IDs
that we already support for application-provided error sources.
