uftp 4.9.3 (new formula)

UFTP is an encrypted multicast file transfer program, designed to
securely, reliably, and efficiently transfer files to multiple
receivers simultaneously. This is useful for distributing large files
to a large number of receivers, and is especially useful for data
distribution over a satellite link (with two way communication), where
the inherent delay makes any TCP based communication highly
inefficient. The multicast encryption scheme is based on TLS with
extensions to allow multiple receivers to share a common key. UFTP also
has the capability to communicate over disjoint networks separated by
one or more firewalls (NAT traversal) and without full end-to-end
multicast capability (multicast tunneling) through the use of a UFTP
proxy server. These proxies also provide scalability by aggregating
responses from a group of receivers.

Closes #9878.
