5e8bb0aa13 An alternative messaging strategy for the OPFS VFS proxy which uses only SharedArrayBuffer and Atomics, instead of worker messages, for communication (only the initial one-time handshake during initialization uses worker messages). It runs speedtest1 approx. 15-20% faster but still 20-ish% slower than WASMFS.

c4b87be3e8 OPFS VFS: moved i/o buffer from per-file to the VFS, and related refactoring, in prep for experimentation with a new inter-worker comms model.

f815011a08 Cut the speedtest1 runtime of the OPFS VFS proxy by approximately 3/4ths via xRead/xWrite buffer-copying optimizations. Still slower than the WASMFS impl by approx. 1/5th.

0e0687ccfc Add sqlite3_web_vfs_list() to JS API. Corrected OPFS VFS's registering itself as the default VFS. speedtest1-worker now uses the xDelete() of both the default VFS and OPFS, to avoid that it starts up with a persistent OPFS test db (the native app calls unlink(), but that unlink call operates on a different virtual filesystem than the OPFS VFS).

f386012069 Numerous cleanups in the JS bits. Removed some now-defunct wasm test files. Expose sqlite3.opfs object containing various OPFS-specific utilities.

c5313afea7 Move the OPFS VFS bits back into api/sqlite3-api-opfs.js. Refactor the OPFS VFS init process to use a Promise-returning function which the client must call, as that eliminates any uncertainty about when the VFS (necessarily activated asynchronously) actually becomes available to the client.

e3cd67603d Refactor JS API amalgamation such that the bootstrapping/configuration is deferred until the whole amalgamation is available, to facilitate providing clients with a way to initialize the API with their own config (noting that we're still one small level of refactoring away from being able to actually do that).
