This adds $INPUT in all places where it was still missing and available.
$INPUT is now also used in places where using $_REQUEST/... was okay in

This makes it possible to find words that include soft-hyphens. However,
search higlighting will not work and I have no idea how to make it work.

This reverts commit 58a22bd0.

It was accidentally pushed to the repo.

$NS is only used in lib/exe/{ajax,mediamanager}.php when no $ID context
is present. The two functions which use $NS in inc/template.php are only
called through those both endpoints, not through doku.php. In doku.php,
$ID is the only correct value, $NS is not kept synchronous with $ID.

Use getNS($ID) in functions which are called through doku.php.

This reverts commit 48714142.
Additionally there is a new fix for FS#2107 that doesn't introduce a lot
of checks but instead ensures that the configuration option can't be set
to negative values when the configuration manager is used.

This fixes an infinite loop in breadcrumbs() and makes the behaviors in
all places where breadcrumbs are used consistent so that non-numeric
values, values < 0 and 0 are treated the same way.
