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

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.
