Various fixes to track down memory handling bugs.
...
Fixed one free-before-time bug with queuing MDP frames.
Some heap corruption bug seems to remain.

Further work on MDP, including dispatching low-priority data when
...
it can fit in frames. A nasty bug in queue code needs fixing.
Also, we only send tick frames at present, and need to add code
for dispatching packets at other times (bandwidth allowance permitting).
So the whole bandwidth management code needs to get finished.

More work on preparing packet payloads for enqueing MDP frames.
...
Also errors for unimplemented crypto modes.

Various fixes and work towards sending MDP frames.
...
Broadcast and unicast addresses are accepted. Some frame headers
are set. Payload is yet to be set, and ciphered &/or signed as required,
and queueing is not yet verified.

MDP ping getting closer: ping loop showing server-returned error
...
messages now works. Server currently reports error when trying to
send MDP_TX frames (since it is not yet implemented), which the
client successfully displays. Onto making the server handle the
MDP_TX frames.

Improved shutdown behaviour to properly handle client mode (don't
...
delete server socket if you are a client). Also added main MDP
ping loop of sending packets. Reading returned packets not yet
implemented. Server handling of MDP_TX packets also not yet
implemented.

Further work on MDP. Client now receives server replies. So we
...
can actually bind an MDP port. Next step is to make use of it to
send a packet.

Added verification that replies come from MDP server

(including dealing with when the server is referenced via a
symlink, and verification by inode/dev is required)

MDP replies almost working, and thus port binding almost working.
...
Just need to add sender verification check, i.e., that it was the
MDP server that replied, and interpret the reply.

Work towards getting MDP working. Still some fun and games with

getting unix domain sockets to play nicely. Some superfluous debug
code is present while working this through.

MDP client socket gets bound to name before sending frame, and

socket file gets deleted when exiting. MDP server doesn't seem
to be able to reply to packets yet -- that's next on the queue to
fix.

More work on MDP. Removed some debug fluff.
...
Added framework for MDP ping, and some work towards MDP port binding
and sending packets with option to wait for reply. MDP server
doesn't yet support port binding, and client doesn't yet support
reading replies.
