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.

80168e3530 Improve debug logging
- add debug.trace to help track down segfaults
- warn about alarms without names (which are then hard to track down).

5985df751d Overhaul debug flags
Replace debugflags_t and DEBUG_XXX bit masks with config schema "debug.xxx"
entries.

No more support for "debug.all".

0e435683f7 Move toprint functions from log.h to str.h
Move alloca_sockaddr() to strbuf_helpers.h

So that stand-alone executables can use them without pulling in the entire
logging framework.

cbc91d11e0 Improve performance timing diagnostics
Add __whence args to fd_func_enter() and fd_func_exit() so that their log
messages get reported from the location of the IN() or OUT() macro, not a line
in performance_timing.c.

Removed diagnostic information from the FATAL() message in fd_func_exit(), and
a comment explaining why (causes SEGV).

39fc4ce6de Issue #30, remove periodic Rhizome fetch alarm
Replace the main-loop scheduled periodic alarm with an "activate" alarm that is
scheduled whenever a fetch candidate is added to any queue, unless the alarm is
already scheduled.

Replace the "rhizome.fetch_interval_ms" config item with
"rhizome.fetch_delay_ms" [default 50], which is the number of milliseconds
between adding a fetch candidate and firing the "activate" alarm.  This allows
time for a few more Rhizome advertisment packets to arrive after the first one,
before deciding which fetches to start first.

Add new `is_scheduled()` alarm primitive.

f472ac9a8d Lots of 'dnahelper' tests, all pass but one
Test fails because DNA helper logic does not yet impose a timeout on receiving
the "DONE" ACK after a request.

86eb482ed9 Replace macros with functions
SET_NONBLOCKING(), SET_BLOCKING(), WRITE_STR() are now set_nonblock(),
set_block() and write_str() respectively, all of which log an error before
returning -1.  There are other useful methods: write_all() treats anything less
than all bytes written as an error; write_nonblock() treats EAGAIN and EINTR as
zero bytes written, and a combination: write_all_nonblock().

calling overlay_check_ticks alarm for some reason, which causes
