a5ba1ecacd Clean up debugging code

INFO messages for starting/stopping servald server.

calling overlay_check_ticks alarm for some reason, which causes

b48fdb6567 added deeper timing checks to reveal that rhizome advertisements 
are the slowest part -- need to add caching of manifests so that
we don't hit the database every interface tick.

0dd5845cdd added instrumentation to detect when servald spends more than 5ms doing 
anything.  Reports which bit of the overlay mesh main loop the time was
spent in, to help track it down.

c5a9321880 Improve debug output (translate IPs & ports into human readable things). 
Revert change to use src_addr as this will break other platforms and needs more thought.

86c5e6945f Don't force signedness for name in overlay_interface_register(). 
I can't see any point to forcing the signedness, it causes warnings on platforms with a signed-char by default.

ea9993dc91 Fix detection on OSX and make detection smarter. 
- Fix lsif() on OSX.
- Make lsif() smarter and avoid non-broadcast and no AF_INET addresses.
- Don't run multiple interface detectors, run one at a time until one works.
- Factor out HAVE_IFADDRS_H code into a separate function into lsif.c with the other interface detection routines.
- Prefer HAVE_IFADDRS_H (random bias..)

8882515d03 Fix compilation on OSX.

- Abstract namespace UNIX domain sockets are Linux only.
- Rework code to reduce indent levels.

30e53f963c fixed various manifest synchronisation bugs, including probably 
the main one that was stopping meshms (large manifests would
practically never get advertised under certain (common) conditions).

4ddb7a5572 fixed bug in overlay_gettime_ms() (start time was 32bits not 64bits,

f90b21ec78 Implement rhizome config options 
rhizome.datastore_path - if not set, reverts to serval instance path
rhizome.enable - if not set, defaults to true

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.

cbc367b1f5 Rewrite server start/status/stop commands 
Now correctly probes for server process existence using kill(pid, 0)
Status command does not dump config (use "config get" instead)
Output uses JNI cli output fields
Stop command uses 5 Hz wakeup, not busy wait while server exits

requires ROOT on android).
