04184761de Internal restructuring of the OPFS sqlite3_vfs in order to facilitate certain experimentation and improve error reporting/hints if it cannot be activated. Deprecate the name sqlite3.opfs.OpfsDb, preferring sqlite3.oo1.OpfsDb for consistency with JsStorageDb and any future DB subclasses.

e6b0154138 Add an explicit warning about the current API-instability of the sqlite3.opfs namespace, which may need to be eliminated based on re-thinking of how the OPFS sqlite3_vfs is registered. Comment changes only - no code.

4245667e35 OPFS VFS: add the opfs-unlock-asap=1 URI flag which tells the VFS to release implicit locks ASAP instead of during VFS idle time. This improves concurrency notably in the test app but brings a significant performance penalty in speedtest1 (roughly 4x slowdown). This is not the final word in OPFS concurrency, but gets us a step further.

aafa022f5b OPFS: if an op which needs a lock is called when no lock has been obtained, automatically lock it at the start of the op and unlock it at the end of that op. This is an attempt to alleviate the cross-tab contention described in [forum post 58a377083cd24a|forum:58a377083cd24a] but it increases speedtest1 run time by approximately 4x. Perhaps auto-lock can be combined with the older idle-time-based auto-unlock to unlock such locks (but not those from xLock()) to improve this?
