Capsicum-sandboxed applications generally cannot use dlopen, as absolute

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
in gen/Symbol.map.
We would also include __flt_rounds, but it's under FBSD_1.3 on arm so
until that's gone we're stuck with it. Likewise, everyone but i386
implements fp[gs]etmask.

pthread_getname_np needs to be provided by libc in order to import
jemalloc 5.3.0.
A stub implementation for libc pthread_getname_np() is added for
_pthread_stubs.c, which always reports empty name for the main thread.
Internal _pthread_getname_np() is not exported, but provided for libc
own use.

the one that looked like it was intended to track versions. That will

Apparently there are applications that resolve dl_iterate_phdr from libc
and try to call the symbol. Our libc only provides stubs for dl* to
satisfy static linker or statically linked binaries, and is not prepared
to this situation.
Add a code to dso libc to find real dl_iterate_phdr and redirect the
call to it.

When libc switched to generation of logs as per RFC 5424,
that change broke application ability to insert specific process id
using ident[N] format, the feature existed for decades.
Some processes rely on it (including logger and syslogd).
Later the regression was fixed but the feature remained undocumented.
This change documents it.

Bracket the kern.vnode sysctl in #ifdef notyet because it results
in massive locking issues on diskless systems.
It is also not clear that this sysctl is non-dangerous in its
requirements for locked down memory on large RAM systems.
There does not seem to be practical use for it and the disabled routine
does not work anyway.
