28d46cce0b Minor cleanups in the opfs-sahpool VFS.

38d1db9b79 Correct opfs-sahpool VFS after the pebkac involving the previous speedtest1 runs. Make that VFS explicitly opt-in to avoid certain unfortunate locking situations.

88af76f62d opfs-sahpool VFS now seems to work, in that it runs fine (and blazingly fast) in speedtest1. Add sqlite3.config options for the high-level configurable parts of opfs-sahpool.

100bc4429a More work on porting the sahpool bits. Revert to random backing-store names because it works better with the capacity-reduction algorithm.

bee3213145 Switch opfs-sahpool to use deterministic backing-store file names. Delay VFS registration until after the pool's files are all opened. Fail vfs init if the client's OPFS API has an async FileSystemSyncAccessHandle.close() method (indicating that it's outdated).

50c61825fc Initial sketches for an alternate OPFS VFS which uses a pool of pre-opened SyncAccessHandles to bypass the need for a dedicated I/O worker and the COOP/COEP HTTP response headers. Currently completely non-functional.
