kvno ASN.1 encoding interop with Windows RODCs
RFC 4120 defines the EncryptedData kvno field as an integer in the
range of unsigned 32-bit numbers. Windows encodes and decodes the
field as a signed 32-bit integer. Historically we do the same in our
encoder in 1.6 and prior, and in our decoder through 1.10. (Actually,
our decoder through 1.10 decoded the value as a long and then cast the
result to unsigned int, so it would accept positive values >= 2^31 on
64-bit platforms but not on 32-bit platforms.)
kvno values that large (or negative) are only likely to appear in the
context of Windows read-only domain controllers. So do what Windows
does instead of what RFC 4120 says.

Replace the "field" half of the ASN.1 encoder machinery with several

This change eliminates the two-way entanglement between atypes and
fields, and makes the encoder more independent of RFC 4120 ASN.1
conventions.
Defining sequences with the preprocessor macros is now slightly more
cumbersome; we need to define a type for each field and then string
them together with an array of struct atype_info *. But it's not so
bad, and hopefully we can auto-generate some of this soon.
*_optional functions now return a bitmask of sequence field offsets
not present in the C type. This will need some more attention before
we add decoding support to the engine, since it means sequence fields
no longer know whether they are optional or not.

(always 0 for the moment).
For atype_tagged_thing, narrow the construction field to six bits and
add an implicit bit. We could remove the construction field if it
weren't for DEFOCTETWRAPPEDTYPE abusing atype_tagged_thing a little
bit, since (normal) explicit tags are always constructed and implicit
tag construction is computed from the base type.
Given how rarely implicit tagging is used, it might be nice to have
separate _IMPLICIT macros rather than an extra argument to every
field. But we already have separate _OPT macros for optional fields
and FIELDOF_STRING vs. FIELDOF_STRINGL, so we start to get a
combinatoric explosion in the number of macros.

Support ASN.1 encoding without the outer tag
In order to support implicit tagging, make it possible to ASN.1-encode
a value without its outer tag, instead remembering the construction
bit of the omitted tag.
A cleaner design would be to have separate functions for encoding a
value's contents and its tag. However, we can't do that for atype_fn
or atype_opaque, and the possible indirections between types and
fields mean we want to stay at the "encode everything" level for as
long as possible to allow implicit tagging of the largest possible
subset of types. If we can get rid of atype_fn, we may be able to
switch to the cleaner design with some adjustments to atype_opaque.

Use content-only ASN.1 primitives
As part of implicit tag support, rework ASN.1 encoding primitives so
that they encode only content, not tags. Combine primitives which
become identical with this change. The new atype_primitive type
invokes a primitive encoder and adds a tag. atype_fn_len is split
into atype_string and atype_opaque, both of which are hardcoded to
use asn1_encode_bytestring.
For the encoders still using macros, create asn1_addprimitive,
asn1_addinteger, and asn1_addstring macros which call the primitive
encoder function and add a tag.

Make ASN.1 struct atype_info more extensible
Instead of including all of the possible type fields in struct
atype_info, use a pointer to a type-specific structure. This might
save a little space, but more importantly, if we get to the point of
exposing this stuff across plugin APIs, it allows ASN.1 type
information to be extensible via defining new atype_type values.
