PAM: Delete old lib and symlinks
Core 119 update delivers an updated PAM whereby the libdir has been changed from /lib to /usr/lib
but the old libraries and symlinks are still presant. Since the system searches /lib before
/usr/lib , the old libs and symlinks are used which ends up in an `LIBPAM_EXTENSION_1.1' not found.

in bug 10592 I added the functionality to use the squid as ram-only cache.
Further it defines the maximum_object_size_in_memory
as 2% of the in the webif defined "Memory cache size".
The maximum_object_size_in_memory should have a useful

test if nameservers with DNSSEC support return "ad"-flagged data
DNSSEC-validating nameservers return an "ad" (Authenticated Data)
flag in the DNS response header. This can be used as a negative
indicator for DNSSEC validation: In case a nameserver does not
return the flag, but failes to look up a domain with an invalid
signature, it does not support DNSSEC validation.
This makes it easier to detect nameservers which do not fully
comply to the RFCs or try to tamper DNS queries.
See bug #11595 (https://bugzilla.ipfire.org/show_bug.cgi?id=11595) for further details.
The second version of this patch avoids unnecessary usage of
grep. Thanks to Michael Tremer for the hint.

set OpenSSL 1.1.0 DEFAULT cipher list to secure value
Only use secure cipher list for the OpenSSL DEFAULT list:
* ECDSA is preferred over RSA since it is faster and more scalable
* TLS 1.2 suites are preferred over anything older
* weak ciphers such as RC4 and 3DES have been eliminated
* AES-GCM is preferred over AES-CBC (known as "mac-then-encrypt" problem)
* ciphers without PFS are moved to the end of the cipher list
This patch leaves AES-CCM, AES-CCM8 and CHACHA20-POLY1305 suites
where they are since they are considered secure and there is no
need to change anything.
The DEFAULT cipher list is now (output of "openssl ciphers -v"):

strongswan: Update to 5.6.2
Fixed a DoS vulnerability in the parser for PKCS#1 RSASSA-PSS
signatures that was caused by insufficient input validation.
One of the configurable parameters in algorithm identifier
structures for RSASSA-PSS signatures is the mask generation
function (MGF). Only MGF1 is currently specified for this purpose.
However, this in turn takes itself a parameter that specifies
the underlying hash function. strongSwan's parser did not
correctly handle the case of this parameter being absent,
causing an undefined data read.
This vulnerability has been registered as CVE-2018-6459.
