ec192e0659 Rename some JS files from X.js to X.c-pp.js to keep the maintainer, and downstream build customizers, aware that those files contain constructs specific to the c-pp preprocessor and will not run as-is in JS.

8ae9545577 Install sqlite3_malloc/sqlite3_free() as the JS-side WASM allocator (as opposed to replacing C-level's malloc()/free() with them). All tests work and this eliminates the potential for allocator discrepancies when using the (de)serialize APIs.

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?

a579f4400d Build fiddle with WASMFS OPFS support and attempt to use it if available. It does not work because of an inexplicable exception in Emscripten-generated code and perpetually-locked db, but it's not yet clear why.
