Subject: [PATCH] qpkg/gobble.c (EXPECT): added variant that just skips over
 expected text

If the package database is sane, then we don't need to check that all
the field names match what we expect. This saves a few more CPU cycles.
However, if anything goes wrong, the consequences may be unpleasant.
Thus, we default to the slow but safe approach.
