Andri Yngvason d418b33dd7 Create dedicated RSA-AES stream
The message format isn't really within the domain of the cipher, so it
doesn't belong to the crypto interface.

Andri Yngvason d7dc9c0db5 server: Set SO_SNDBUF to 65536
The previous value of 4096 caused a very bad performance regression
with GnuTLS.

Andri Yngvason 0cdbf6a602 stream: Add exec_and_send function
This allows us to execute a function right before a leaves the send queue
and is really only useful for NTP as far as I can tell.
