xlocale.3: Comment out reference to atof_l(3), atoi_l(3), atol_l(3), atoll_l(3)
These manual page references do not exist.
lagg.4: Change the reference for /etc/rc.conf from a reference link
.Xr -> .Pa based on the context within the manual page it is used.
buf.9: Remove .Xr entries from the file
The buf.9 manual page contains a commented out .Xr reference.
The <filmmein> 9 entry is a placeholder and has been removed for
clarity.

This version of swab function simplifies the logic of swapping adjacent
bytes. Previous version of swab() used an arbitrary unrolling, which was
relevant back in the day but unnecessary for modern compilers, as if the
input size is known at compile time, they can do it automatically.
This version of swab() is inspired by musl.
A similar version can be found at: https://github.com/openbsd/src/blob/master/lib/libc/string/swab.c

Fixes: 6e6cd03c91 libc/quad: narrow list of symbols exposed on i386
Differential Revision: https://reviews.freebsd.org/D44879
I put the symbols in the wrong file (should have been
lib/libc/sys/Symbol.map), added a duplicate pdfork entry due to a botch
rebase, and there seems to be a issue with gcc13/binutils not exposing
the symbols so revert the whole thing while I debug.
This reverts commit ee632fb9eb.
List them in the symbol map rather than using the __sym_default to
expose them. This will allow later improvements in the stub
implementations in libc.so.

The (optional) third argument of fcntl is sometimes a pointer so change
the type to intptr_t. Update the libc-internal defintion (actually used
by libthr) to take a fixed intptr_t argument rather than pretending it's
a variadic function. (That worked because all supported architectures
pass variadic arguments as though the function was declared with those
types. In CheriBSD that changes because variadic arguments are passed
via a bounded array.)

These provide standard APIs, but are implemented using another system
call (e.g., pipe implemented in terms of pipe2) or are interposed by the
threading library to support cancelation.
After discussion with kib (see D44111), I've concluded that it is
better to keep most public interfaces in libc with as little
as possible in libsys.

The old timezone(3) function has long since been obsolete and has a
fatally flawed interface. Retain this function for compatibility
purposes, but shift to providing the offset from UTC in the timezone
variable, whether or not the timezone observes summer time in the
'daylight' variable. Document the tzname variable that's already been
set. Also make _tztab() static. It's not used in libc (or anywhere in
the tree) and it's not exported as a public dynamic symbol.
