2d09ec545e Improve configuration dump to log
Refactor much of the new code in log.c

Add new functions: cf_load_strict() and cf_reload_strict() for use by the
server, which does not want to overwrite its in-memory config at all if there
is any defect in the config file.  However, commands always want to overwrite
the default in-memory config, even with a defective config file, so that
logging has a chance to succeed.

Added `log_format.dump_config` boolean config option

2252fdcaa7 created tool for automatically finding IN()s without matching
OUT()s or where return() is used instead of RETURN().
Added OUT() to end of all functions using IN() that lacked it to
make it easier to statically analyse this invariant.
Fixed several return instead of RETURNs detected through use of
this tool. #49

- include file size information in Rhizome transfer messages.
- reduce output when debug.rhizome_rx is set.

a6a81a0f64 Improve server signal handling
Use sigaction(2) instead of deprecated signal(2), allowing SEGV et al to be
received in handler and therefore in re-spawned server.

Receive SIGSEGV et al in a separate handler function which kills the server
with the same signal if it does not re-spawn.

Log a GDB backtrace on SEGV et al before exiting or respawning.

Rename config option "serval.respawn_on_signal" to "server.respawn_on_crash".

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.
