pacdiff: rework search type handling, add --find option

Change cmd tests to if (( USE_FIND ))... as it is cleaner.  All search
cmds have an option and a variable initialized to zero. The active option
should be set to 1.  Add a switch to exclude multiple search options.
set the default when all are equal to zero.

pacdiff: improve speed, accuracy finding active configs using pacmandb

This is a new search type, using -p or --pacmandb options. It reads
config file locations directly from the local pacman db. It will find
active configs anywhere they are defined in installed packages. It is
not dependant on outside configs such as updatedb.conf or scanning a
large set of directories for find.

This will find more pacnews than find when searching with the current
default of /etc, and it is faster than both find and updatedb when
searching the entire fs. When run directly after an update, the local db
is more likely to be cached than all files in /etc or / as other methods
read. This will increase performance further post upgrade.

After a package is removed and a pacsave is created, this method will
not find these pacsaves until the base config is added to the local db
again. These files have no influence in a working system and only take
up a few blocks of disk space.

Active configs need to be dealt with immediately to keep a system
working. pacsaves related to removed configs can remain for weeks or
months without problems. I would recommend occasionally running other
methods such as --locate to remove them.

pacdiff: provide an --output option to show any .pac* files

This is an option to just echo's the pacnews/pacsaves instead of merging
or removing them. This can be used to check the config status such as in
a cron job without modifying the system.

Only note backup file changes with -Qkk

Backup files are expected to be changed and should not be flagged by -Qkk.
Note changed back-up files in -Qkk but do not count them as altered. Do
not report backup files in -Qqkk.

Warn when directory ownership differs between filesystem and package

We currently only warn if a directory's permissions differ, but using -Qkk
on my system shows that directory permissions tend to change in packages
reasonably frequently without notice.  Provide a warning in such cases
so that it can be altered.  Example output:

(1/1) reinstalling nginx
warning: directory ownership differs on /var/lib/nginx/proxy/
filesystem: 33:0  package: 0:0

Remove setlocale usage from the backend

Using setlocale in the backend is bound to lead to frontend issues
and we have have been using epoch in our databases since April 2007
(commit 47622eef).  Remove support for old style times.

Report missing directory if we can not initialise alpm library

When pacman failed to initialise the alpm library due to the database
directory being missing (either via the root not existing or the database
directory itself not existing), it just printed the non-informative
message "could not find or read directory".  Add the directory
information the the error output.  E.g.:

error: failed to initialize alpm library
(could not find or read directory: /this/does/not/exist/var/lib/pacman/)
