Several manual pages for releng/14.3 incorrectly claim that features
were first introduced in FreeBSD 15.0.
I discovered these by running:
git checkout origin/releng/14.3
git grep -F '.Fx 15.0'

Some sanitizers need to be able to use dl_iterate_phdr() after stopping
the rest of the process, but it's very hard to do so reliably as a
non-participant in the main logic of the program.
Introduce _dl_iterate_phdr_locked to bypass the locking that's normally
required for dl_iterate_phdr() and slap some scary warning on it. It
will remain undocumented and probably shouldn't be used for anything
else.

(cherry picked from commit d84fd89ecd404ffbf629381d2dde14fd79b39402)
Rather than calling calloc() to allocate space for a page size array to
pass to getpagesizes(), just follow the getpagesizes() implementation
and allocate MAXPAGESIZES elements on the stack. This avoids the need
for the allocation.
While this does mean that a new libc is required to take advantage of a
new huge page size, that was already true due to getpagesizes() using a
static buffer of MAXPAGESIZES elements.

Due to memfd_create(3)'s construction of a path to pass to shm_open2(2),
it has a much larger than typical dependency footprint for a system
call wrapper (the list currently includes calloc, memset, sprintf, and
strlen). As such, split it off into its own file under libc/gen to
lighten libc/sys's dependency list.

fabs, __infinity, and __nan are universally implemented so declare them

We would also include __flt_rounds, but it's under FBSD_1.3 on arm so

implements fp[gs]etmask.

jemalloc 5.3.0.
A stub implementation for libc pthread_getname_np() is added for

Internal _pthread_getname_np() is not exported, but provided for libc
