proposal: Add supported KE methods to default ESP/AH proposals, but optional
...
This allows accepting clients that send proposals with non-optional KE
methods during rekeying, while still accepting clients that use the
previous non-KE default proposals.

Add configure option to disable testing key exchange methods
...
If this is used, the functionality to set a private key/value/seed for
key exchange methods is removed (including from the interface to avoid
accidentally forgetting to wrap implementations and uses of set_seed()).
The set_seed() method is assigned outside the INIT() macro to avoid
potentially undefined behavior (preprocessing directives in macro
arguments).
The test done by the crypto tester is a simple functionality test.

ha: Add support to sync IKE and Child SAs with multiple key exchanges
...
Synchronization for the additional transforms in the IKE and Child SA
proposals is added. Details of the IKE_SA synchronization are changed
to support IKE_INTERMEDIATE exchanges that cause multiple HA_IKE_ADD
messages and key derivations. The cache has been extended to handle
multiple such messages.

proposal: Add ESN transform to default ESP AEAD proposal
...
The commit mentioned below adds an AES-GCM default proposal for ESP. That
proposal does not include any ESN or non-ESN transform to indicate if
extended sequence numbers are supported.
A standards-compliant peer will include one or more ESN support transforms,
and will be unable to select this proposal due to a proposal mismatch.
Fix the default AES-GCM proposal by adding a NO_ESN algorithm. While ESN has
been supported in the Linux kernel for a while, having it in the default
proposal can be problematic with kernel-libipsec or on other platforms.
