056a71562f OPFS concurrency test: add a URL flag to enable/disable unlock-asap mode.

e79cb67c35 Add an experimental OPFS VFS-specific URI flag, opfs-unlock-asap, which tells the VFS to release implicit locks ASAP. This permits higher concurrency but hurts performance considerably. This may or may not be obsoleted by other concurrency-related experimentation.

others are needed.

ff5e4ecced This is the first in what is anticipated to be a long sequence of incremental 
changes aimed at improving aggregate query processing, and in particular
helping aggregate queries take better advantage of indexes on expression.
The end goal is to resolve ticket [99378177930f87bd], though it remains to
be seen whether or not I can get there with this approach.
