* OPFS VFS: translate createSyncAccessHandle() exceptions which appear to be ↵stephan2022-12-02
| | | | | locking violations to SQLITE_BUSY. This seems to improve concurrency considerably even with a reduced retry count of 5 (was 6). FossilOrigin-Name: 0d36021d107d3afca190ad61c3380536ad0cc2d493d345d48f9f9c1191741128

Deprecate the name sqlite3.opfs.OpfsDb, preferring sqlite3.oo1.OpfsDb for consistency with JsStorageDb and any future DB subclasses.

* Add an experimental OPFS VFS-specific URI flag, opfs-unlock-asap, which ↵stephan2022-11-23
| | | | | 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. FossilOrigin-Name: d23c917013485ec2793125221f3936b05c39d6eca941629fb819b6b4aa714520
* Initial infrastructure for adding a mode to the OPFS VFS which causes ↵stephan2022-11-23

* OPFS: if an op which needs a lock is called when no lock has been obtained, ↵stephan2022-11-10
| | | | | 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?

Re-add worker1 open-from-bytearray using sqlite3_wasm_vfs_create_file() but it's untested (requires a new interactive test app or maybe reconsideration).
