New ASN.1 embed macro.
New ASN.1 macro ASN1_EMBED. This is the same as ASN1_SIMPLE except the
structure is not allocated: it is part of the parent. That is instead of
FOO *x;
it must be:
FOO x;
This reduces memory fragmentation and make it impossible to accidentally
set a mandatory field to NULL.
This currently only works for SEQUENCE and since it is equivalent to
ASN1_SIMPLE it cannot be tagged, OPTIONAL, SET OF or SEQUENCE OF.
