Change HTTP request buffer pointers from (const char*) to (char*)
because some Rhizome operations can modify received data in-place, eg,
when decrypting it.
Now tokens are included in each row instead of a single token in the
enclosing JSON object. Only puts tokens on the first row, and
thereafter all rows with a rowid higher than for the previous row that
had a token.
New ".rowid" output field from rhizome add, import, extract, export
operations. (Also added missing ".inserttime" and "date" fields to
some operations.)
Use new "rhizome add file" .rowid output field to check output of of
/restful/rhizome/bundlelist.json
Write test case assertions using jq(1) utility, increase from four
bundles to 100.
Fix bugs in HTTP server content generation logic.
Make payload content generator read payload 4KiB at a time, to
always read on filesystem block boundaries for performance. Increase
size of payload in relevant test case.
