[incremental] Patch: FYI: reset error count

[Tom Tromey]

I'm checking this in on the incremental-compiler branch.

I'm not sure why I didn't do this before.  This resets errorcount and
sorrycount at the start of a new job.  Without this, the server will
hang if the forked child crashes for some reason.
