The result of g_strsplit_set () may contain empty strings which
are saved even though they carry no real meaning. This creates an
erroneous behaviour in which the interface and external programs
make use of these invalid empty strings.

This commit makes sure to remove such empty strings from the list,
before setting the ignored hosts.

Fixes #3109

(cherry picked from commit cc2c9e61)

Getting an object from the storage adds a reference to it, so this needs
to be unreffed when the page is disposed to not prevent cleanup from
happening.

Passing a non-null auxerror can allocate something to pass a password
check error back. The variable is unused however, so let's plug the
potential leak by passing NULL instead, which is allowed per the
pwquality docs.

(cherry picked from commit 0d63fad9)

To avoid parsing possible a pwquality.conf config file, the pwquality
settings are only loaded once. However, they are static and never freed,
resulting in a possibly incomplete cleanup.

To fix this, let's use CcObjectStorage and a very simple GObject wrapper
to store the pwquality settings, and have them freed when g-c-c exits.

The combo row only has 3 entries, with the last one being centered,
which should therefore have index 2. Right now you can select "Remains
Centered", but the row appears empty afterwards as the index is now
incorrect.

Fixing this now matches the corresponding behavior from
`ua_zoom_behaviour_row_changed_cb()`.
