The goal was all, but obviously we made some exceptions.  Any function
that works on the pool internals can't have access to a pool, because they
are working on the internals.  Any time function doesn't get a pool,
because the time type is a 64-bit integer, and any function moved down
from Apache doesn't follow this model.

Also, it is important to note that APR-utils doesn't have this design
goal, just APR itself.  APR-utils has a different goal than APR.  Because
APR-utils is supposed to use APR to do everything non-portable, we can say
with almost 100% accuracy which functions do and do not require a pool.
