General further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 3-Clause license.

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.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Some consumers of PAM remove the /dev/ component (i.e. login), while
others don't (i.e. su). We must ensure that the /dev/ component is
removed to ensure that the utmpx entries properly work with tools such
as w(1).

Let pam_lastlog use random ut_id's.

By using random values for ut_id, not based on the TTY name, it is
possible to run for example login(1) multiple times on the same TTY,
without overwriting any previous records.

The output of w(1) will then be as follows:

| 12:26PM up 2 days, 2:31, 5 users, load averages: 0.01, 0.03, 0.03
| USER TTY FROM LOGIN@ IDLE WHAT

Let pam_lastlog use utmpx instead of libulog's utmpx interface.

It will still use ulog_login(3) and ulog_logout(3), which will remain
present.

Merge from head at r201628.

# This hasn't been tested, and there are at least three bad commits
# that need to be backed out before the branch will be stable again.

Several refinements to libulog's API.

- Only set the fields in the ulog_utmpx structure that are valid for the
command in question. This means that strings like "shutdown" or "~"
are not visible

Several refinements to libulog's API.

- Only set the fields in the ulog_utmpx structure that are valid for the
command in question. This means that strings like "shutdown" or "~"
are not visible to the user anymore.
- Rename UTXF_* to UTXI_*, indicating the indexation, instead of using
the `antique' filename. If we ever get rid of utmp, it makes little
sense calling it by its old name.

Convert pam_lastlog(8) to libulog.

The information used by the "Last login:"-line is obtained by using
ulog_setutxfile(3) to switch to the lastlog database. Login and logout
are performed using the utility functions ulog_login(3) and
ulog_logout(3).

This also means we must build libulog during bootstrap.

Fix strict aliasing breakage in PAM modules (except pam_krb5, which needs
more work than the others). This should make most modules build with -O2.
