Using parse_time() directly actually overwrites the next member in the
child_cfg_create_t struct, which is start_action, which can cause
incorrect configs if inactivity is parsed after start_action.
Fixes#2954.
A temporary DROP policy is added to avoid traffic leak
while the SA is being updated. It is added with
manual_prio set but when the temporary policy is removed
it is removed with manual_prio parameter set to 0.
The call to del_policies_outbound does not match the original
policy and we end up with an ever increasing refcount.
If we try to manually remove the policy, it is not removed
due to the positive refcount. Then new SA requests fail with
"unable to install policy out for reqid 1618,
the same policy for reqid 1528 exists"

Instead, create a socket when necessary. Apparently, it can prevent
the agent from getting terminated (e.g. during system shutdown) if e.g.
charon-nm is still running with an open connection to the agent.
In 7b7290977 ("controller: Add option to force destruction of an IKE_SA")
the 'force' option was added as 3rd parameter to controller_t::terminate_ike.
However in vici's 'clear_start_action', the argument was incorrectly
placed as the 2nd parameter - constantly sending 0 (FALSE) as the
'unique_id' to terminate, rendering calls to 'handle_start_actions'
having undo=TRUE being unable to terminate the relevant conn.
For example, this is log of such a bogus 'unload-conn':
strongswan[498]: 13[CFG] vici client 96 requests: unload-conn
strongswan[498]: 13[CFG] closing IKE_SA #9
strongswan[498]: 13[IKE] unable to terminate IKE_SA: ID 0 not found
strongswan[498]: 09[CFG] vici client 96 disconnected
here, the unloaded conn's IKE id was 9, alas 'terminate_ike_execute'
reports failure to terminate "ID 0".
Fix by passing 'id, FALSE' arguments in the correct order.

Up to now it was assumed that the RSA public key exponent is equal to 2^16+1.
Although this is probably true in most if not all cases, it is not correct
according to the TPM 2.0 specification.
This patch fixes that by reading the exponent from the structure returned
by TPM2_ReadPublic.

Adds all IPs to RADIUS Accounting-Stop messages even those not claimed by
a client. For instance, if the connection fails with FAILED_CP_REQUIRED,
adding the unclaimed addresses allows the RADIUS server to release the
leases early.
Fixes#2856.
All directories are now considered relative to the loaded swanctl.conf
file, in particular, when loading it from a custom location via --file
argument. The base directory, which is used if no custom location for
swanctl.conf is specified, is now also configurable at runtime via
SWANCTL_DIR environment variable.
Closesstrongswan/strongswan#120.
The functional reference created by ENGINE_init() was never released,
only the structural one created by ENGINE_by_id(). The functional
reference includes an implicit structural reference, which is also
released by ENGINE_finish().

Makes sure to adopt active and queued Quick Mode tasks if the peer
reauthenticates the IKE_SA while creating lots of CHILD_SAs.

This is particularly important for higher number of segments, but even
with small numbers there is a significant difference. For instance,
with 4 segments the fourth segment had no IPs assigned with the old
code, no matter how large the pool, because none of the eight bits used
for the segment check hashed/mapped to it.
