Some distros still care about `/bin` vs `/usr/bin`. This commit makes
it so all binaries are always installed to `/bin`/`/sbin`. The only way to
restore the previous behaviour of installing some binaries to
`/usr/bin`/`/usr/sbin` is to revert the patch.
Synchronize how passwd(5) and shadow(5) describe the password field.
Reorder the descriptions more logically.

Closes#185
If vipw is suspended (e.g. via control-Z) and then resumed, it often gets
immediately suspended. This is easier to reproduce on a multi-core system.
root@buster:~# /usr/sbin/vipw
[1]+ Stopped /usr/sbin/vipw
root@buster:~# fg
/usr/sbin/vipw
[1]+ Stopped /usr/sbin/vipw
root@buster:~# fg
[vipw resumes on the second fg]
The problem is that vipw forks a child process and calls waitpid() with the
WUNTRACED flag. When the child process (running the editor) is suspended, the
parent sends itself SIGSTOP to suspend the main vipw process. However, because
the main vipw is in the same process group as the editor which received the ^Z,
the kernel already sent the main vipw SIGTSTP.
If the main vipw receives SIGTSTP before the child, it will be suspended and
then, once resumed, will proceed to suspend itself again.
To fix this, run the child process in its own process group as the foreground
process group. That way, control-Z will only affect the child process and the
parent can use the existing logic to suspend the parent.
Using hard-coded access vector ids is deprecated and can lead to issues with custom SELinux policies.
Switch to `selinux_check_access()`.
Also use the libselinux log callback and log if available to audit.
This makes it easier for users to catch SELinux denials.
Drop legacy shortcut logic for passwd, which avoided a SELinux check if uid 0 changes a password of a user which username equals the current SELinux user identifier.
Nowadays usernames rarely match SELinux user identifiers and the benefit of skipping a SELinux check is negligible.

With this, it is possible for Linux distributors to store their
supplied default configuration files somewhere below /usr, while
/etc only contains the changes made by the user. The new option
--enable-vendordir defines where the shadow suite should additional
look for login.defs if this file is not in /etc.
libeconf is a key/value configuration file reading library, which
handles the split of configuration files in different locations
and merges them transparently for the application.
suidubins should be suidusbins, since these binaries are installed
${prefix}/sbin. This historically hasn't broken the build because
chmod of newgidmap/newuidmap succeeds, causing make to think the command
succeeded. Configuring shadow with --with-fcaps removes these final two
entries and exposes the chmod failure to make.
