update for apache2-mod_nss

- mod_nss-CVE-2013-4566-NSSVerifyClient.diff fixes CVE-2013-4566:
If 'NSSVerifyClient none' is set in the server / vhost context
(i.e. when server is configured to not request or require client
certificate authentication on the initial connection), and client
certificate authentication is expected to be required for a
specific directory via 'NSSVerifyClient require' setting,
mod_nss fails to properly require certificate authentication.
Remote attacker can use this to access content of the restricted
directories. [bnc#853039]

- glue documentation added to /etc/apache2/conf.d/mod_nss.conf:
* simultaneaous usage of mod_ssl and mod_nss
* SNI concurrency
* SUSE framework for apache configuration, Listen directive
* module initialization
- mod_nss-conf.patch obsoleted by scratch-version of nss.conf.in
or mod_nss.conf, respectively. This also leads to the removal of
nss.conf.in specific chunks in mod_nss-negotiate.patch and
mod_nss-tlsv1_1.patch .
- mod_nss_migrate.pl conversion script added; not patched from
source, but partially rewritten.
- README-SUSE.txt added with step-by-step instructions on how to
convert and manage certificates and keys, as well as a rationale
about why mod_nss was included in SLES.
- package ready for submission [bnc#847216]

- generic cleanup of the package:
- explicit Requires: to mozilla-nss >= 3.15.1, as TLS-1.2 support
came with this version - this is the objective behind this
version update of apache2-mod_nss. Tracker bug [bnc#847216]
- change path /etc/apache2/alias to /etc/apache2/mod_nss.d to avoid
ambiguously interpreted name of directory.
- merge content of /etc/apache2/alias to /etc/apache2/mod_nss.d if
/etc/apache2/alias exists.
- set explicit filemodes 640 for %post generated *.db files in
/etc/apache2/mod_nss.d
