Better integrate max message size
(cherry picked from commit ec8e552)
Fixes #1225
See #1213, #1217, #1220 and #1223
The TL;DR is that unusual network issues caused this client to incorrectly allocate over 1 GiB of memory due to reading an invalid frame. An old FIXME comment suggested that a maximum be set on this. I implemented this in 6.4.0 and forward-ported it here.
