e7e8b2d630 fixed bug in RFS size patching. 
A lot of debug output tweaks to track the problem down.

005c7bb7bb overhauled link metric to heavily weight recent notices over old 
ones so that we can adapt to changing routes quickly.

0a71486f68 Fixed generation of broadcast address in one place where it 
wasn't choosing a random BPI.

3fb1e6cafe Fixed a bug in node lookup, and added a duplicate broadcast 
supression check.

5ac83f9ca1 Replaced use of HLR with keyring for phone number lookups and 
other functions.  Not yet tested.

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).
 2012-03-23 07:06:57 +10:30

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.

738b70b513 Test and fix ACTION_CREATEHLR idempotency code: 
- refactor hlrSid() to not return pointer to static buffer, take 3rd arg instead
 - introduce SID_STRLEN macro constant, use it everywhere
 - reformat some code for readability

1eb4c34015 Renamed mphlr.h to serval.h 
(also some temporary debugging has been added in some places)

3fed04e6cd Added some extra checks for memory corruption (of course now that I 
am looking, the problem is not happening).

2a3721506b More debugging output fixes and bug fixes for overlay operation. 
Added proper check to suppress frames claiming to come from
ourselves ( necessary for squelching multi-hop broadcasts, although
we need an extra step there of having transaction ids on broadcast
frames so that we can flood smartly).

44c0765981 Various debugging code cleanups. 
Fixed some address resolution bugs (for when sender address is not
fully known).
There is still a bug in dequeuing packets though it seems.

2a2f8d752f reception and processing of advertised routes now works :) 
Indeed the core of the overlay mesh is now in place and nodes
on simple meshes discover each other. Plenty of bugs are sure
to remain.

8aa57edee3 Added code to add node advertisements to interface tick packets. 
Looks like it works.  No code to decode it yet.

ec22b5df0d Added infrastructure to tick route tables by progressively touching 
all neighbours and nodes over a bounded timespread so that route
ticking doesn't add excessive delay/jitter.

144f3ee4b1 Thinned out debug messages and fixed SID generation bug to make sure 
that it always generates a valid SID, i.e., not beginning with 0.

78e3bfc4a3 Finally looks like selfacknowledgement acks get sent and can be 
decoded.  Now to actually use them ...

b6ce25ab24 Believe I have found and stemmed the memory corruption bug, although

74efa738be Now sends acks to self-announcements, but uses index-based-abbreviation
