Fix decoding of message headers for messages with lengths >= 2^24.

recvMsg was interpreting buf[1] as the payload format instead of buf[0];
since compressionNone (the only thing supported) == 0, recvMsg got lucky
for message lengths under 2^24, which has buf[1] == 0.

Fix the error, and ditch the constants in recvMsg. I think they were the
cause of the bug.

Also make encode fail more clearly if someone tries to transmit a
message that exceeds 2^32 bytes.

Fixes #399.
