crypto: Fix bug with takover of EC resource type

enif_open_resource_type() must be called even during repeated loading
of same library. Otherwise the resource type will be deallocated
when the old module instance is purged.
erts: Add the +sfwi system flag

+sfwi Interval
    Set scheduler forced wakeup interval. All run queues will be scanned
    each Interval milliseconds. While there are sleeping schedulers in
    the system, one scheduler will be woken for each non-empty run queue
    found. An Interval of zero disables this feature, which also is the
    default.

    This feature has been introduced as a temporary workaround for lengthy
    executing native code, and native code that do not bump reductions
    properly in OTP. When these bugs have be fixed the +sfwi flag will
    be removed.

Fix list-valued Vendor-Specific-Application-Id config

Commit f0a36c79 broke the handling of such configuration, resulting in a
function clause error in diameter_capx if the list was not of length 3,
and faulty extraction of application id's otherwise.  Only record-valued
config was properly interpreted.
