3ea6d4f324 monitor interface announces new peers. 2012-05-21 12:47:53 +09:30

990a8f3057 Add support for srtuct ucred on BSD. 
This requires building with _GNU_SOURCE to get access to struct ucred on Linux. Previously the test failed on every platform except glibc <2.8 or so.

Building with _GNU_SOURCE causes TRUE to be defined so we can't use this as a variable anymore, and MIN/MAX so don't define our own.

d11258cefc Overhaul debug flags 
Config debug flags are now represented as individual items, eg:
   servald config set debug.verbose yes
   servald config set debug.rhizome yes
instead of aggregated, eg:
   servald config set debug verbose,rhizome  <-- no longer works

Added a debug flag "debug.all" that can be set and cleared, over which
individual flag sets/clears take priority.

Slimmed down dna.c by moving some globals and functions to the files where they
are used.

Default command line (help message) is now the new style, not the deprecated
style.

e746557a08 Fix bug in overlay_gettime_ms() 
The sequence start time was only getting set in overlay_interface_init(), which
was not always called, or was called after overlay_gettime_ms() had already
been used.

Added FATALF(), FATAL() and FATAL_perror() macros.

Removed a bunch of debug statements no longer needed in monitor.c and server.c.

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.
