98ed0406c5 Refactor Rhizome result handling
- Introduce the new 'struct rhizome_bundle_result' that contains a
  rhizome_bundle_status enum value and an optional, nul-terminated
  string that provides an explanation of the cause of the status; add
  functions to construct, query, and free the struct

- Replace 'enum rhizome_add_result' with 'struct rhizome_bundle_result',
  removing an unnecessary level of enum interpretation

- Make rhizome_fill_manifest() return 'struct rhizome_bundle_result' and
  add logic to check that the supplied author SID is correct (previous
  behaviour was: if an incorrect author SID was supplied but the correct
  author could be found in the keyring, then the incorrect one was
  silently ignored)

- Simplify the response code in rhizome_restful.cc to take advantage of
  the new 'struct rhizome_bundle_result'; in particular, the mapping
  from 'enum rhizome_bundle_status' codes to HTTP status codes is now
  expressed in a single switch statement

- Fix some minor failures in test scripts revealed by the changes

7d9a5faa4e Move if(config.debug.xxx) tests into DEBUGF()
Original DEBUG() and DEBUGF() macros renamed to _DEBUG() and _DEBUGF()
New DEBUG() and DEBUGF() macros, first argument is flagname
New DEBUGF2(foo, bar, ...) macro does if(config.debug.foo||config.debug.bar) test

the secret and author are both supplied, by setting the BK field so the
secret can be recovered from the manifest later

e743e4d7f9 Create authorless bundle from bundle secret

only to update a bundle whose secret was known from its creation.

72040517e1 New enum rhizome_payload_status
Refactor a lot of Rhizome bundle storage code to use the new "enum
rhizome_payload_status" instead of mysterious int values to represent
the outcome of the operation.

8db5f9c14a Merge branch 'anyservice' into 'development'
Allows any valid "service" manifest field in the "rhizome add file"
command

Many improvements in Rhizome manifest parsing; stricter manifest syntax
rules (no comment or blank lines, field names must be alphanumeric
identifiers), faster preliminary manifest inspection when receiving
manifest advertisements or syncing manifests

The 'development' branch introduces "struct socket_address" which
coincidentally fixed the recently encountered Linux kernel 3.12
recvmsg(2) EINVAL problem, so that 'rhizomeprotocol' tests which fail on
the 'anyservice' branch will pass after this merge

Remove rhizome_manifest 'errors' field

Replace rhizome_manifest 'warnings' with 'malformed'

Replace rhizome_manifest 'manifest_bytes' with 'manifest_body_bytes' and

New function rhizome_manifest_inspect() -- lightweight manifest parser

New ".rowid" output field from rhizome add, import, extract, export
operations.  (Also added missing ".inserttime" and "date" fields to
some operations.)

45442d3eb4 Rewrite bundle author authentication
Replaced 'int has_author' manifest element with new 'enum authorship'
element to record the result of author authentication, to avoid
repeating expensive crypto operations.

Separated the handling of bundle secret arguments from author lookup and
authentication.  The new rhizome_apply_bundle_secret(m,bsk) is now
called at the top level to set the manifest secret key (if it
validates), and thereafter there is no need to pass the 'bsk' argument
to any other functions, as they can simply check the 'haveSecret' field
of the manifest.

Removed rhizome_extract_privatekey() which combined author lookup and
bundle secret validation, and replaced it with functions that only deal
with the author: rhizome_lookup_author() and rhizome_authenticate_author().

Renamed other functions to make their purpose and effect clearer.

Formalised the semantics of only storing AUTHENTICATED author SIDs in
the 'author' column of the MANIFESTS table, which necessitated a change
to a 'rhizomeops' test case: when adding a file using a BK-less
manifest, the author column is set to null, so the Rhizome list output
does not show the bundle as ".fromhere" and does not give an author for
that bundle.

bacba19dc1 Refactor manifest: specific setter functions
Replace generic rhizome_manifest_set() and rhizome_manifest_set_ll()
with per-field setter functions, eg, rhizome_manifest_set_filesize().
Struct rhizome_manifest elements for all known fields, to replace the
use of rhizome_manifest_get() and rhizome_manifest_get_ll() everywhere:
sender, recipient, service, name, date, bundle_key.

Add boolean validity flags for binary blob types, to avoid having to compare
with many bytes of all-zero to detect presence, eg, has_sender, has_recipient,
has_author, has_bundle_key.  These maintained by the setter functions.

Rename existing manifest struct elements to be the same as their field
names: fileLength -> filesize, journalTail -> tail.

More use of unsigned int, size_t and uint64_t for payload sizes, offsets, byte
counts, etc. especially in rhizome_store.c and meshms.c.  More uniform use of
size_t to dimension memory buffers.  Fix some printf(3) style format strings
for 64-bit correctness on 32-bit systems.  Use new constant RHIZOME_SIZE_UNSET
instead of -1 to indicate unknown dimension, and explicitly assert its absence
before comparisons and arithmetic, for safety.

Replace some 'int' loop variables with 'unsigned' where appropriate.

Fix bugs discovered in MeshMS bundle private/public key generation and
bundle secret key handling for export/extract commands.

Instrument the first MeshMS test case to aid debugging.

New debug config flag: debug.manifest logs all modifications to all manifest
fields by setter functions.

Rename debug config flag: debug.rhizome_bind -> debug.rhizome_sql_bind.

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
