1. Update the release date in the ChangeLog.
2. Move some compiler guards around to hush warnings depending on the
build options.
3. Fix a string name for ECDSA P521 algo.
4. Fix a stray static function definition.

1. There were a couple spots during a large file transfer where the
client rekeying the session would interrupt the transfer and/or
reset the amount of file data transfered. Fixed that with a check
for WS_CHAN_RXD.
2. Added a build option to interrupt a file transfer after 2 minutes.
Large files will take longer.
