075f9c7c27 Use uint64_t for Rhizome manifest version
Instead of int64_t.  Fixes some -Wsign-compare warnings.

Replace sqlite_exec_int64() with sqlite_exec_uint64().

Also store rowid as uint64_t, and use 0 not -1 to indicate
unset.

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

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.

Overhauled the file fetch queue logic in rhizome_fetch.c.

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.

27a0a6eeb5 Introduce struct __sourceloc
Replaces (const char *file, unsigned int line, const char *function) arguments
to all logging functions, simplifies malloc/free tracking code in
overlay_buffer.c and Rhizome manifest alloc/free tracking in rhizome_bundle.c.

Use __HERE__ macro instead of (__FILE__, __LINE__, __FUNCTION__) everywhere.

Special __NOWHERE__ macro is equivalent to (NULL, 0, NULL).

Declare net.c functions in new "net.h" header, so log.c doesn't have to pull
in the entire "serval.h" just to use write_str().

Facilitates progress on issue #2.
