ldconfig: remove ignored -v (verbose) option

The -v option used to print useful information when operating on a.out
format libraries. After the removal of a.out support, it was accepted
but did not have any effect.

Remove the option and update the man-page.

While here mention the set of historic options that are accepted but
ignored: "-elf", "-s", and "-v".

The FILES section contained outdated information and did not mention
the way library directories of optional ports and packages are
included in the library search path recorded in the hints file.

The description of the "-B" option was incorrect (described a planned
change) for big-endian platforms (powerpc64). These do still default
to big-endian hints files, since the current version of the "pkg"
program expects the hints file to be in native byte-order.

ldconfig: support hints files of either byte-order

Make the ldconfig program accept hints files in little-endian and
big-endian format on all architectures.

The default format is the native byte-order of the respective host.
This is expected to change when a version of the pkg command is
available that implements support for either byte-order in its
internal ldconfig function. (Already committed in the development
tree of the pkg utility, a release is expected at the end of Q1/2024).

This update adds the -B option to the ldconfig program. It enforces
the creation of a big-endian hints file on a little-endian host.
The main purpose to is support of tests with non-native byte-order
files on little-endian hosts. It will be removed when all supported
FreeBSD releases use little-endian hints files by default.

When little-endian hints files are generally used, support of
either byte-order in libexec/rtld can also be removed.

When support for big-endian hints files is no longer required,
the COND_SWAP macro in ldconfig and rtld shall be replaced by
le32toh(), which just return their argument on little-endian
architectures.

ldconfig(8): check for no-args command line after options are parsed

Default action for ldconfig is specified as -R AKA 'append', and for
no-args (without options changing default actions), ldconfig should
append empty list of directories to current list. But because the check
was done before options were parsed out, presence of any option turned
off default rescan.

As result, innocently-looked commands like `ldconfig -v' were interpreted
as setting directory hints list to one specified on the command line,
i.e. empty.

various: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.
