Fixes build issues due to use of deprecated GLib macros/functions
Updated Glade file to GTK 3.2
The NM backend now supports reauthentication and redirection (#852).
Previously used reqids are now reallocated, which works around an issue on FreeBSD where the kernel doesn't allow the daemon to use reqids > 16383 (#2315).
On Linux, throw type routes are installed in table 220 for passthrough policies. The kernel will then fall back on routes in routing tables with lower priorities for matching traffic. This way, they require less information (e.g. no interface or source IP) and can be installed earlier and are not affected by updates.
For IKEv1, the lifetimes of the actually selected transform are returned to the initiator, which is an issue if the peer uses different lifetimes for different transforms (#3329). We now also return the correct transform and proposal IDs (proposal ID was always 0, transform ID 1).
IKE_SAs are now not re-established anymore (e.g. after several retransmits) if a deletion has been queued (#3335).
Added support for Ed448 keys and certificates via openssl plugin and pki tool.
Added support for SHA-3 and SHAKE128/256 in the openssl plugin.
The use of algorithm IDs from the private use range can now be enabled globally, to use them even if no strongSwan vendor ID was exchanged (05e373aeb0).
Fixed a compiler issue that may have caused invalid keyUsage extensions in certificates (#3249).
