[OPEN-ILS-DEV] PATCH: osrf_hash.[ch] (performance tweak)

[Scott McKellar]

This patch boosts the performance of an osrfHashIterator a bit, by
reusing the "current" buffer whenever possible instead of freeing and
reallocating it on every iteration.

I wrote a benchmark that repeatedly traverses a 27-item hash table.
The new version is about 10% faster.  This improvement is not as
dramatic as I had hoped for, but it's easy to get, and it won't hurt.

...and I belatedly wish everyone at Equinox a happy equinox.
