This is a repackaging effort for the work i originally pushed in
6035. This segment of the PR provides UDP session handlers for
bind and reverse sessions, a Windows Metasm stager (really the
TCP stager with a small change), and a pair of socat payloads for
testing simple UDP shells. Netcat or any scripting language with
a sockets library is sufficient to use these sessions as they are
stateless and simple.
Testing of this PR requires rex/core #1 and rex/socket #2
The SSL testing which was being done on 6035 is backed out, left
for a later time when we can do DTLS properly.
