53c1b1c04c Filesystem Heirarchy Standard (FHS) paths
If no instance directory specified, then use paths like
/etc/serval/serval.conf
/var/cache/serval
/var/log/serval
/var/run/serval
etc. for files, instead of all in a single directory.

Log all directory creation as INFO messages.

Interpretation of log.file.directory_path has changed slightly.

Updated servald configuration tech doc.

9ebef81a49 Formalise "rhizome add file" exit status
Formalise add-bundle result in "enum rhizome_bundle_status"

Rewrite rhizome_manifest_finalise(), rhizome_find_duplicate() and
rhizome_add_manifest() to return enum rhizome_bundle_status

New function rhizome_manifest_check_stored() that compares a manifest
with its stored counterpart and returns enum rhizome_bundle_status

Remove redundant rhizome_manifest_check_sanity(), consolidating all
manifest validation rules in rhizome_manifest_validate(), which now
checks the 'id' field is present, and that 'sender' and 'recipient' are
both present for MeshMS

Correct manifest finalisation logic: set the 'finalised' flag in
rhizome_manifest_validate(), not in rhizome_manifest_verify() (which
sets 'selfSigned'), and consistently clear 'finalised' flag in all
attribute setter functions

Remove manifest 'ttl' field and all references thereof (leaving unused
space in Rhizome BAR)

Rename some payload functions for clarity

Order by descending ROWID, which is functionally the same as descending
inserttime but more reliable

Replace '_offset' cursor element with rowid first-last range to record
the expanding window of rows already returned, which allows release and
re-open of cursor mid-listing without missing rows or producing duplicates

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.

390655580d Add 'rhizome delete' and 'rhizome clean' commands

rhizome_clean() function now produces an optional report of its changes

rhizome_fail_write() and rhizome_finish_write() now log WARNings not
ERRORs if the SQL DELETE FROM FILES or DELETE FROM FILEBLOBS statements
fail

Refactor rhizome_open_read() to use sqlite_exec_int64()

Ensure that 'rhizome extract' and 'rhizome dump' commands return exit
status of 1 in "not found" conditions, not 255, which is reserved for
