a217a4af09 Require a button click to start the OPFS concurrency tester, rather than simply launching all N workers immediately on page load.

46a692c08b Upgrade ext/wasm/c-pp-lite.c to its newer sibling because we've reached the older one's limits. This renames c-pp-lite.c to libcmpp.c to maintain both the SCM- and code lineage but that may end up looking a bit weird because the diff between the two is vast.

976b50620a Merge opfs-wl into trunk, not so much for the "opfs-wl" VFS, which is stil tentative (working fine but with little perceived benefit), but for the "opfs" VFS cleanups which necessarily happened around it.

237fce8205 Extend the JS pre-bootstrapping configuration to include an option to disable inclusion of any given extension VFS (not the default VFSes, like memdb). The primary motivation for this is to give people who don't use OPFS to a way to keep the OPFS VFSes from loading their proxy workers, which are expensive.

57d0fe254a For backwards compatibility, ensure that the "opfs" VFS does not specifically require Atomics.waitAsync() (a new requirement of "opfs-wl"), but make use of it if available. Only apply jitter to the concurrency test runs at random intervals.

ac63b524ac Add some jitter and duration info to the opfs concurrency tester. Ensure that Atomics.waitAsync() is available for opfs-wl. Further testing has shown that Web opfs-wl is consistently fairer about doling out contested locks but it's dog slow compared to the original VFS under moderate concurrency. In single-connection use they're effectively on par.

7b9cd03c0a This Web Lock impl can reliably run a single OPFS connection but rather unreliably 'loses' workers with higher counts, presumably due to deadlock or deadly embrace (how _all_ of them can deadlock at once is unclear, but clearly a bug).

cef3ff74cd The opfs-wl lock hang has been traced to starvation between the WebLock and the tight wait-on-VFS-calls Atomics.wait() loop. This can reportedly be resolved with another level of indirection in which the WebLock takes over the wait-on-VFS-calls part until it's unlocked, returning to the global loop when it's done. That exceeds this morning's ambitions but is next to try out.

a2d3a54f80 An initial attempt to plugging opfs-wl into the build but its initial handshake with the async half collides with the opfs VFS's handshake, causing bootstrapping to fail miserably. We'll need to either devise a handshake which can differentiate between the two instances or we'll need to preprocess sqlite3-opfs-async-proxy into two copies. Move the (now) three copies of some common code shared by the opfs pieces into a preprocessor #include.
