proposal: Add a compat alg for ChaCha20Poly1305 with explicit key length

The keylength fix for ChaCha20Poly1305 (5a7b0be2) removes the keylength
attribute from the AEAD transform. This breaks compatibility between
versions with the patch and those without. The ChaCha20Poly1305 AEAD
won't match in proposals between such versions, and if no other algorithm
is available, negotiating SAs fails.

As a migration strategy, this patch introduces a new string identifier for a
ChaCha20Poly1305 proposal keyword which uses the explicit keylength, exactly
as it was used before the mentioned patch. Administrators that care about
the use of that AEAD with old clients can temporarily add this keyword to
the list of proposals, until all clients have been upgraded.

The used approach is the least invasive, as it just adds an additional
keyword that can't do any harm if not explicitly configured. Nontheless
allows it the administrator to smoothly keep ChaCha20Poly1305 working,
even if upgrading all peers simultaneously is not an option. It requires
manual configuration edits, though, but we assume that ChaCha20Poly1305
is not that widely used, and not as the only transform in proposals.

Removing the compat keyword in a future version is an option; it might
be helpful for other implementations, though, that falsely use an
explicit key length in ChaCha20Poly1305 AEAD transforms.

dhcp: Bind server port when a specific server address is specified

DHCP servers will respond to port 67 if giaddr is non-zero, which we set
if we are not broadcasting.  While such messages are received fine via
RAW socket the kernel will respond with an ICMP port unreachable if no
socket is bound to that port.  Instead of opening a dummy socket on port
67 just to avoid the ICMPs we can also just operate with a single
socket, bind it to port 67 and send our requests from that port.

Since SO_REUSEADDR behaves on Linux like SO_REUSEPORT does on other
systems we can bind that port even if a DHCP server is running on the
same host as the daemon (this might have to be adapted to make this work
on other systems, but due to the raw socket the plugin is not that portable
anyway).

dhcp: Fix destination port check in packet filter

The previous code compared the port in the packet to the client port and, if
successful, checked it also against the server port, which, therefore, never
matched, but due to incorrect offsets did skip the BPF_JA.  If the client port
didn't match the code also skipped to the instruction after the BPF_JA.
However, the latter was incorrect also and processing would have continued at
the next instruction anyway.  Basically, DHCP packets to any port were accepted.

What's not fixed with this is that the kernel returns an ICMP Port
unreachable for packets sent to the server port (67) because we don't
have a socket bound to it.

Allow strongSwan to be spawned as non-root user

 1) start up as a non-root user
 2) avoid modprobe()'ing IPsec kernel modules into the kernel, which
