on Windows and Macos, most filesystems are case-insensitive,
which can lead to dangerous situations
one example is when another program (not copyparty or its UI) wants to
rename a file from `Foo` to `foo`; the program will probably start by
checking if `foo` exists and then delete it, however this would match
`Foo` and confuse the program into deleting the wrong file
fix this by adding a VERY EXPENSIVE detector to prevent this,
by listing the parent folder and checking if the case matches
this check will auto-enable when a case-insensitive FS is detected on
startup, but option `casechk` (global or volflag) can override this
given the following config:
* volume /a mapped to /srv/nas/
* volume /b mapped to /srv/nas/foo/
* anyone can read volume /a but not /b
accessing /a/foo/ would incorrectly fail because the xvol-check
would select /b based on its abspath being physically closer,
not considering that the same abspath is reachable from /a
extends idp-auth to also accept a collection of headers (and
expected values of those headers) and map those to certain users
useful for Tailscale-User-Login and similar
togglebutton in the ui switches between 2 (off/default) and
1 (on/quick) confirmations; global-option `--qdel` sets the default
setting `--qdel=0` changes the togglebutton to switch
between 1 (off/default) confirmations and 0 (on)
in other words, when the ui-button is enabled, it
always reduces the number of confirmations by one
the unix-permissions of new files/folders can now be changed
* global-option --chmod-f, volflag chmod_f for files
* global-option --chmod-d, volflag chmod_d for directories
the expected value is a standard three-digit octal value
(User/Group/Other) such as 755, 750, 644, 640, etc
until now, ${u} would match all users,
${u%-foo} would exclude users in group foo,
${u%+foo} would only include users in group foo
now, the following is also possible:
${u%-foo,%-bar} excludes users in group foo and/or group bar,
${u%+foo,%+bar} only includes users which are in groups foo AND bar,
${g%-foo} skips group foo (includes all others),
${g%-foo,%-bar} skips group foo and/or bar (includes all others)

file hashing became drastically slower in recent chrome versions;
* 748 MiB/s in 131.0.6778.86
* 747 MiB/s in 132.0.6834.160
* 485 MiB/s in 133.0.6943.60
* 319 MiB/s in 134.0.6998.36
the silver lining: it looks like chrome-bug 1352210 is improving
(crypto.subtle, the native hasher, now scales with multiple cores)
* 133.0.6943.60: speed peaked at 2 threads; 341 MiB/s, 485 MiB/s
* 134.0.6998.36: peak at 7; 193, 383, 383, 408, 421, 431, 438, 438
* 137.0.7151.41: peak at 8; 210, 382, 445, 513, 573, 573, 585, 598
MiB/s when hashing with 1, 2, ..., 7, 8 webworkers respectively
on a ryzen7-5800x with 2x16g 2133mhz ram
characteristics of versions between v134 and v137 are unknown
(cannot find old official builds to test), but v137 is a good
cutoff for minimizing risk of hitting chrome-bugs
meanwhile, hash-wasm scales linearly up to 8 cores;
0=328 1=377 2=738 3=947 4=1090 5=1190 6=1380 7=1530 8=1810
(0 = wasm on mainthread, no webworkers)
but it looks like chrome-bug 383568268 is making a return,
so keep the limit of max 4 threads if machine has more than
4 cores (and numCores-1 otherwise)
