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

3c1f727603 Because version 3.52.0 was withdrawn, that means QRF has never been 
officially released.  Hence the new nMultiInsert field of the spec
can be moved out of the extensions area and into the main part of the
spec, and the version number can drop back from 2 to 1.

abc82c49c2 Revamp the QRF insert-mode optimization of [659ff6ab55802507]. The 
control value is now nMultiInsert.  Multiple rows are added to each INSERT
statement until the number of bytes in that statement exceeds the
nMultiInsert value.  The CLI uses a default value of 3000, which provides
a good balance between speed and prepare-statement size.  The output
from ".dump" now loads nearly 2x faster in some cases.

efa8633fd8 Enhance QRF with the mxTuple field, which if greater than 1 causes the 
QRF_STYLE_Insert style to group as many as mxTuple adjacent rows into
a single INSERT statement.  The field is accessible using the -mxtuple
option in the TCL interface, and the --mxtuple option in ".mode".  The
output of the ".dump" and ".fullschema" commands responds to the current
--mxtuple setting.

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.

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.
