Bug #7186: Fix an excessive request size limitation that broke big-requests.
MAXBUFSIZE appears to be a leftover of some previous time. Instead, just
use maxBigRequestSize when bigreqs are available (limiting buffers to ~16MB).
When bigreqs are not available, needed won't be larger than the maximum
size of a non-bigreqs request (256kB).
