aa543e1766 Various fixes and work towards MDP ping working. 
MDP clients can now request the set of local addresses.
Framework is improved to avoid info leaks by sending more bytes
in an MDP frame than are necessary, but without having to bzero
almost 2KB each time.

d1bb637cba Fixed bug with sending of broadcast frames (nexthop was not being 
set for broadcast frames).

6759a26720 Cleaned out some debugging output after tracking down and fixing 
memory corruption bug.  Next challenge is to find out why broadcast
MDP packets are not getting dispatched properly (is trying to treat
broadcast address as unicast address it seems).

2b42f77ccf Fixed some bounds checking, and added some fairly rigorous memory 
handling debug aids. No known memory corruption bugs remain, I
think.

13d1d3084e 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.

c7dd475d50 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.

2d63e91c96 More work on preparing packet payloads for enqueing MDP frames.

30e2540470 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.

c71ddbbd18 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.

6e3fe903d9 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.

7ee72b3cba 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.

2bfb6eb569 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)

67c4577b55 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.

8e6f6ee925 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.

5fe959f033 Fixed reading of unix domain socket connections to provide a large 
enough buffer to get the full socket name of the sending party.

8884339e31 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.

70497df7b5 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.

081a9f496b Put back a pile of files needed for building on osx, and also required 
for building on other platforms (i.e., configure framework, including
the .in files that are needed to build configure and Makefile, and the
sqlite code that is required for stand-alone building without external
dependencies, e.g., on non-android platforms, and looking ahead to
symbian where we will need a single self-contained binary as we cannot
assume the presence of an sqlite3 library as we can on android).
Any further changes to the build environment should not be committed
until it has been verified that building from a clean checkout on osx,
followed by configure and make actually works.
