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.

b23b28b16d Changed rhizome manifest signature block type code semantics to

de95bb3971 Gracefully disable rhizome if the database cannot be opened
- close database after every command line operation
- don't cache rhizome enabled configuration
- don't send advertisements unless the database is open and the web server is running
- don't provess advertisements unless the database is open

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.

499c4018bf Imported ref10/ implementation of crypto_sign from supercop-20120525
as recommended a while back by Dan Bernstein as offering the fastest
implementation of the crypto_sign() primitives for ARM.
Indeed this implementation IS faster. See comparison below for a
Rock 500 handset (800MHz(?) ARM6, no NEON):

Original ref/ implementation on an R500 stock rom (non-rooted)::
mean signature generation time = 96.80ms
mean signature verification time = 272.20ms

ref10/ implementations on an R500 stock rom (non-rooted):
mean signature generation time = 4.00ms
mean signature verification time = 13.00ms

Approximately 20x speed up, just like that :)

259b9a9d24 Logging/debug improvements: __WHENCE__, __whence
Introduce __WHENCE__ macro and a block comment in log.h explaining it.

In "primitive" kinds of functions, rename 'whence' arguments to '__whence' and
use WHYF(), WARNF(), DEBUGF() macros instead of calling logMessage() directly.

52ccd07020 Issue #17, improve speed of "rhizome extract manifest"
In the case that the MANIFESTS 'author' column is not NULL, do not perform a
full bundle secret verification in order to clear the '.readonly' flag, just
check whether the author's SID is present in the keyring with a proper-size
rhizome secret.

3f1f495d68 Issue #17, overhaul manifest author crypto logic
Add test case for new feature of the "rhizome add" command: if the author SID
is not specified (empty arg) then it searches the keyring for the author.

Removed "authorSid" argument from several functions that also take a struct
rhizome_manifest * arg, since the author, if known, is now supplied in the
struct.

Improve return value handling and refactored some rhizome crypto code.

Replace ".selfsigned" column with ".author" and ".fromhere" columns in
output of "rhizome list" command.  (Note that a "sender" column is
already present.)

Add 'author' field to struct rhizome_manifest.

Log all fully rendered SQL statements on DEBUG_RHIZOME.

test function to be able to assert authorship of files.

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.

3040d2b665 Add Rhizome DB retries on SQL statement preparation
It turns out that if the DB is locked, sqlite_prepare_v2() call can return
SQLITE_BUSY.  The retry logic (implemented for issue #2) only provided for
sqlite_step() to return SQLITE_BUSY.  It was a fairly straightforward matter to
extend the retry logic to cover statement preparation in an equally general
fashion.

The problem was observed while diagnosing failures in the rhizomeprotocol
DirectPush test case: the "servald rhizome list" command was failing due to a
locked database.  See issue #9.

e015f0670b Switched to new BAR format with 15 bytes of BID prefix, and TTL
at the end, and log2(filesize) instead of filesize.  Equally
importantly BAR construction and parsing now uses #defines for
field sizes and offsets instead of it being hardwired without
meaningful documentation.
WILL BREAK BACKWARD COMPATIBILITY WITH PREVIOUS BUILDS.
YOU MUST DELETE AND REBUILD YOUR RHIZOME DATABASE AS OLD-FORMAT
BIDs WILL BE IN THERE AND GET SENT, AND STRANGE THINGS WILL HAPPEN.
This break with backwards compatibility is only reasonable to
consider because we have not yet had an official build using the
new Rhizome with old BAR format.  0.08 uses old Rhizome.  #9

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.

Now returns series of "I have [newer]"'s and "Please send me"'s,
consisting of a 1 byte ID (0x01 or 0x02 respectively), followed
by the 64bit BID prefix from the BAR.  As with all of Rhizome
Direct at present, the geo bounding box is ignored for now.
