485229e147 Enhance sqlite3.wasm.xWrap.FuncPtrAdapter to be able to handle sqlite3_create_function() and friends and reimplement those bindings to use this feature (this will also simplify certain session API bindings). Interal API changes only with no client-side breakage.

75c04ba89c Simplify the signature for JS functions, as opposed to function pointers, passed to sqlite3_exec(), eliminating the superfluous initial two arguments. Update related tests to demonstrate both function-passing approaches.

4099b3cab3 Replace JS-side use of SQLITE_TRANSIENT with the new SQLITE_WASM_DEALLOC, reducing the amount allocation/copying required by sqlite3_bind_blob/text() and sqlite3_result_blob/text(). Remove the 'experimental' log message from the virtual table tests.

027afccdcd Reimplement JS's sqlite3_bind_text/blob() with hand-written bindings to permit more flexible inputs. Add automated JS-to-C function conversion to sqlite3_busy_handler(). sqlite3.wasm.xWrap()'s '*' argument conversion no longer treats JS strings as C-strings: those conversions require explicit opt-in via the 'string' converter (or equivalent).

a4d04c59ba Update wasmfs.make to get WASMFS building again, but changes made to OPFS-over-WASMFS since we last tested it have made it incompatible with how we used it. It can now only be used from worker threads, eliminating the one benefit it had over the sqlite3_vfs OPFS implementation. Remove/amend references to WASMFS in the docs and remove all WASMFS-specific test app links from index.html.

e9f740e484 Expose a JS-friendly subset of sqlite3_config() to JS, with the notable caveats that (1) setting up the JS bindings requires starting the library, making sqlite3_config() illegal to call and (2) calling sqlite3_shutdown() in order to make it legal to call sqlite3_config() may undo certain JS-side library initialization. Move sqlite3_(de)serialize() into the int64-mode-only bindings because of their int64 args.
