a23612428b make rhizome over mdp block size configurable. 
1K seems too big to be reliable on our prototype UHF radio links,
as CRCs fail almost all the time. #48

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.

b66d8d6c5b Fix bug in 'rhizome direct pull' 
Was not fetching payload of remote bundle, just manifest.  The problem was
caused by a change of logic recently to not activate any queued fetch
candidates immediately, but wait until the next fd_poll(), so that parsing a
single packetful of rhizome advertisments would start fetching the most
important one first, instead of the first one parsed.

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.

65ea612e27 Fix bugs revealed by Rhizome stress test 
Overhauled the file fetch queue logic in rhizome_fetch.c.

Now the 'rhizomeprotocol' stress test passes in approximately 5 minutes on my
2009-vintage Dell laptop.

Added a call to rhizome_enqueue_suggestions() in rhizome_fetch_close() so that
a new Rhizome GET request is sent as soon as a fetch slot becomes free, instead
of waiting for the (default 5 second) timer to trigger the next GET.

2e7d19a3f7 Issue #9, fix rhizome direct push and sync tests 
The "rhizome direct push" command (and also sync) was not waiting for the
server's HTTP response, so it was exiting before the server had finished
storing the bundle, which led to a race with the subsequent "assert
bundle_received_by" test.  Fixed by adding the missing code to receive the HTTP
response.

Refactored the code used for parsing HTTP responses in rhizome_fetch.c, and
used it in rhizome_direct_http.c.

17ef2249e4 Issue #9, rewrite rhizome_import_bundle() 
Objective is to avoid having to call system("servald rhizome import ...") to
handle a Rhizome direct POST /rhizome/bundle request.  Antiquated code in and
around rhizome_import_bundle() needs much cleaning up, as indicated by some
TODO comments.  Invocations must unnecessarily write the manifest into a file,
when they already have it in memory, ready to pass to the function.

All the 'rhizomeops' tests pass, but two 'rhizomeprotocol' tests are broken
by the changes in this commit.
