Reimplement pagezero() as ifunc. As pagezero() is only used in pmap.c,
move ifunc to that file.

diff: Fix pagination leak
* Drop an unnecessary variable and rename pidfd to procd.
* Rewinding stdout serves no purpose, so stop doing it.
* Don't bother freeing memory or setting the global status right
before erroring out.
* Error out if dup(2) or dup2(2) fail.
* In the unlikely case that our pipe is equal to stdout, we need to
record that information so we don't close it when cleaning up.
* Don't bother closing a descriptor before dup2(2)ing to it.
* Don't forget to close the the process descriptor after reaping the

diff: Add test case for pagination resource leak
The pagination code leaks either processes or descriptors or both,
depending on the exact version of the code you have. Add a test case
which exercises this leak to facilitate fixing it.

asan: Use memset_early() to fill shadow memory
__builtin_memset() calls are replaced with calls to memset(), but that
can't be used before ifunc relocations are processed if the
implementation is selected at boot time. Meanwhile, the sanitizer may
emit calls to __asan_set_shadow_*() as soon as locore jumps into C code,
before ifuncs are selected.
Just unconditionally use memset_early() to work around this.

mtree: stop creating /usr/share/doc/ncurses
In base 68ad2b0d7af2a the ncurses html documentation was removed, and
entries added to ObsoleteFiles.inc to get rid of /usr/share/doc/ncurses,
but the directory was still being re-created via BSD.usr.dist. Remove it
from there too.

pwd: Clean up and adopt POSIX semantics
According to POSIX, the default should be -L. Based on code history,
whoever first wrote BSD pwd(1) could not figure out how to implement
-L and therefore made -P the default (and only) option. Support for -L
was later added, but the default was never changed.
Clean up the code, make -L the default, and rewrite getcwd_logical() to
reject paths that contain dot or dot-dot, as required by POSIX.

diff: Report I/O errors in Stone algorithm
In the legacy Stone algorithm, we do a first pass over the files to
check if they're identical before we start diffing them. That code
would correctly set the exit status if an I/O error was encountered,

include/stdckdint.h: make the header compatible with C++
by removing the cast to _Bool. The _Bool type is not defined for C++,
and the specification from the gcc info doc states that the return
type of the __builtin_{add,sub,mul}_overflow() is bool already.
This is done instead of including stdbool.h to avoid namespace
pollution, since defining bool from stdckdint.h simingly is not
sanctioned by ISO/IEC 9899:2024.
