Stuff that should still be done on the ASN.1 encoder conversion:
-* Add support for opaque objects (pre-encoded fields, or ANY), and fix
- up those remaining encoders (e.g., asn1_encode_sam_challenge_2) that
- need them.

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

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

exported probably.
-* More compact encoding: For tags and optional-field bit positions,
- encode N+1, and use 0 for "none", then make the field unsigned.
- Currently the fields are signed, non-negative values hold useful
- data, -1 means "none", and MIN..-2 are unused. Changing this will
- either let us reduce the field size one bit, or extend the maximum
- tag/bitpos value from 2**(N-1)-1 to 2**N-2.
+* More compact encoding: For struct atype and struct cntype, we could
+ use structures with a common base type (similar to Xlib events)
+ instead of a base structure with a void pointer, to save the cost of
+ a pointer for each type. Doing this might not be strictly correct
+ C.
-* More compact encoding: Use a union with designated initializers, or
- some ugly casting, to make the structures smaller by not having all
- fields present when we never use all of them at once. The union
- approach is certainly more appealing, aside from the little detail
- that it won't work on Windows unless we do all the initialization at
- run time.
