This is consistent with what other uid-morphing utilities
do, i.e. jexec(1), su(1) etc.

This is expensive and useless call.  It has been useless since Alexander
melifaro@ moved the forwarding table to nexthops with passive invalidation.
What happens now is that cached route in a inpcb would get invalidated
on next ip_output().

These were the last users of pfctlinput(), so garbage collect it.

Finish 02e05b8faec1:
* add gateway matcher function that can be used in rib_del_route_px()
 or any rib_walk-family functions. It will be used in the upcoming
 migration to the new KPI
* rename gw_fulter_func to match_gw_one() to better signal the
 function purpose / semantic.

Turns out there's two hidden a.out dependencies. pxeldr.S assumes it has
access to the a.out header from /boot/loader and cdboot.S assumes that
/boot/loader is also a.out and doesn't use boot2.

So, go back to making a.out files for these and adjust the size checks
to use ls, but we only need to check loader.bin. Trim the size we check
against by 2,000. The difference in size between loader and loader.bin
is about 3000 bytes, but clang15 produces binaries that are a smidge
bigger so we need to relax the check just a little and accept some
additional risk for the moment.

Add some comments to loader's Makefile about this.

The default ones are install them to /usr/libdata/pkgconfig, and we can't
use this path for compat libraries, so we use /usr/lib<suffix>/pkgconfigi here.

Previously, it would only ignore failures due to csmapper conversion
failure.  It may be the case that the input string contains invalid
sequences that also need to be ignored.

A good example of //IGNORE application is sanitizing user- or remotely-
specified strings that are expected to be UTF-8; perhaps as part of a
pipeline that will feed the result into a system less tested against or
tolerant of illegal UTF-8 sequences.

A future commit will actually implement //IGNORE so that applications
using base iconv can, e.g., sanitize UTF-8 strings.  To do this, the
iconv_std module needs to be able to determine the minimum width for any
given encoding so that it can skip that many bytes in the input buffer.
This is mainly an issue for UTF-16 and UTF-32.

This commit bumps shlib versions to 5 for libiconv modules to reflect
the ABI change.  It also fixes OptionalObsoleteFiles to remove the
libiconv modules if WITHOUT_ICONV is in use.

re: _ENCODING_MB_CUR_MIN, note that this file (citrus_stdenc_template.h)
is included at the bottom of an encoding *implementation*, so the
implementation is free to #define it prior.  UTF1632 is a good example,
as it redefines the minimum to be a property on the encodinginfo, and
the minimum is set to 2 or 4 bytes for UTF-16 and UTF-32 respectively.
