MHD uses "whatever is left" (minus some reserves depending on what phase
processing is in) -- first for the receive buffer, and later for the
send buffer (re-using space from the receive buffer).  In both cases it
is minus headers (headers sent and headers received!) and management
data structures.

The objective is simple: we must not use more than the memory limit per
connection, and within that constraint we make the buffers as big as we
(safely) can.
