release
Harden a change to SqliteTestUtil.assert() in the previous checkin to handle a null second argument.
Expose sqlite3_get/set_auxdata() to wasm. Minor test app CSS tweaks.
Major restructuring of opfs-sahpool to improve maintainability and hopefully make it easier to reuse these pieces in the upcoming JSPI-based VFS experiment.
Latest side-stream jaccwabyt/wasmutil.
