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

f465f3a9ee Add lots of profiling to assist in debugging
- made some debug output conditional.
- make it possible to debug slip decoding without getting swamped by other output.
- Improve reporting of unnamed schedule() calls.
- always collect performance statistics, and report on any excess
  use (>1sec in every 3), even if debug.timing is not enabled.
- include file size information in Rhizome transfer messages.
- reduce output when debug.rhizome_rx is set.
