 Stuff that should still be done on the ASN.1 encoder conversion:

-* Convert PKINIT encoders, after we have test cases.

 * Make offsetof uses conforming.  Currently we may use foo.bar or
   foo[0] as fields.

-* More compact encoding: For tags and optional-field bit positions,

-  Currently the fields are signed, non-negative values hold useful

-* More compact encoding: Use a union with designated initializers, or

-  that it won't work on Windows unless we do all the initialization at
