session: increase max ctrl msg size
Type: fix Connect ctrl message recently outgrew the maximum ctrl msg size, so increase the limit. Also add static asserts for messages that could potentially exceed the limit. Change-Id: I0d3e32e0d4d67d7e222cff14ddba59a0c3fb8b00 Signed-off-by: Florin Coras <fcoras@cisco.com> (cherry picked from commit e24a4bc023b880cb01aeaf8ffea98f44dd66ef4a)
