Martin Willi b4b3959b22 stream-service: move CAP_CHOWN check from plugins to service constructor 
A plugin service can be a TCP socket now, so it does not make much sense
to strictly check for CAP_CHOWN.

Martin Willi 19cb07b890 automake: replace INCLUDES by AM_CPPFLAGS 
INCLUDES are now deprecated and throw warnings when using automake 1.13.
We now also differentiate AM_CPPFLAGS and AM_CFLAGS, where includes and
defines are passed to AM_CPPFLAGS only.

Tobias Brunner 1091edede8 capabilities: CAP_CHOWN might be required by many plugins opening UNIX sockets 
But as the sockets will be created with the user/group of the running
process this might not be required as no change may be needed.

Martin Willi a8c9454423 kernel-interface: add an exchange initiator parameter to add_sa() 
This new flag gives the kernel-interface a hint how it should priorize the
use of newly installed SAs during rekeying.

Consider the following rekey procedure in IKEv2:

Initiator  ---    Responder

I1 -------CREATE-------> R1
I2 <------CREATE--------
   -------DELETE-------> R2
I3 <------DELETE--------

SAs are always handled as pairs, the following happens at the SA level:

  * Initiator starts the exchange at I1
  * Responder installs new SA pair at R1
  * Initiator installs new SA pair at I2
  * Responder removes old SA pair at R2
  * Initiator removes old SA pair at I3

This makes sure SAs get installed/removed overlapping during rekeying. However,
to avoid any packet loss, it is crucial that the new outbound SA gets
activated at the correct position:

  * as exchange initiator, in I2
  * as exchange responder, in R2

This should guarantee that we don't use the new outbound SA before the peer
could install its corresponding inbound SA.

The new parameter allows the kernel backend to install the new SA with
appropriate priorities, i.e. it should:

  * as exchange inititator, have the new outbound SA installed with higher
    priority than the old SA
  * as exchange responder, have the new outbound SA installed with lower
    priority than the old SA

While we could split up the SA installation at the responder, this approach
has another advantage: it allows the kernel backend to switch SAs based on
other criteria, for example when receiving traffic on the new inbound SA.

Martin Willi 0a54d3e1a1 load-tester can dynamically install a dedicated external IP for each IKE_SA 
For consistency, the local/remote parameters have been replaced by the
initiator/responder options. As initiator, the initiator option can
be overriden by an addrs section taking key/value pairs with address
pools to use on a specific interface.
