db: fix mysql large blobs, other changes
...
MySQL:
- support multi-packet data rows
- fixed very old length-coding bug (24 vs 32 bit length)
- support large params via long-data packets
- 'any' pseudo-type for parameters
- distinguish 'blob'/'text', 'var-string'/'var-binary'
- read 'text' results as string, not bytes
SQLite3:
- enabled sql types tests

db: fix memory leaks
...
- sqlite3: table prevented pst gc unless close-on-exec
- statement cache wrongly disabled close-on-exec
(not a leak, just gc'd very slowly)
- limit statement cache size

db: fixed issues with statement finalization (don't use weak hash)
...
In some cases, statements were disappearing from statement-table
without being finalized; this makes disconnect fail.
(I was only able to produce the problem when the db lib was
instantiated in a sub custodian that is later shutdown....
like the way the rackunit gui runs the test suite.)

Eliminated interface test (shallow) in favor of method test
(correct, recursive). Also made vstmts work with virtual-connections.
