Merge branch 'variadic-enumerators'

This adds several changes to enumerator_t and linked_list_t to improve
portability.  In particular to Apple's ARM64 iOS platform, whose calling
convention for variadic and regular functions are different.  This means
that assigning a non-variadic function to a variadic function pointer,
as we did with our enumerator_t::enumerate() implementations and several
callbacks, will result in crashes as the called function will access the
arguments differently than the caller provided them.

To avoid this issue the enumerator_t interface is now fully variadic.
A new mandatory method is added, venumerate(), that takes a va_list with
the arguments provided while enumerating.  enumerate() is replaced with
a generic implementation that prepares a va_list and calls the
enumerator's venumerate() implementation.  As this allows passing the
arguments of one enumerator to another it avoids the five pointer hack
used by enumerator_create_nested() and enumerator_create_cleaner().
To simplify the implementation of venumerate() a helper macro is provided
that assigns values from a given va_list to local variables.

The signature of the callback passed to enumerator_create_filter() has
also changed significantly.  It's now required to enumerate over the
original enumerator in the callback as this avoids the previous in/out
pointer hack. The arguments to the outer enumerator are provided in a

Similar changes to avoid such five pointer hacks affect the signatures

methods.  For the latter the return type also changed from status_t to
bool, which is important as SUCCESS is defined as 0, so checks for ==
SUCCESS will now fail.

Merge branch 'avoid-rekey-loss'

This changes the behavior during IKEv2 CHILD_SA rekeyings to avoid
traffic loss.  When responding to a CREATE_CHILD_SA request to rekey a
CHILD_SA the responder already has everything available to install and
use the new CHILD_SA.  However, this could lead to lost traffic as the
initiator won't be able to process inbound packets until it processed the
CREATE_CHILD_SA response and updated the inbound SA.  To avoid this the
responder now only installs the new inbound SA and delays installing the
outbound SA until it receives the DELETE for the replaced CHILD_SA.  The
messages transporting these DELETEs could reach the peer before packets
sent with the deleted outbound SAs reach the respective peer.  To reduce
the chance of traffic loss due to this the inbound SA of the replaced
CHILD_SA is not removed for a configurable amount of seconds after
the DELETE has been processed.

Fixes #1291.
