This simplifies the ASN1_get_object calling convention and removes
another significant source of tasn_dec.c complexity. This change does
not affect our PKCS#7 and PKCS#12 parsers.
Update-Note: Invalid certificates (and the few external structures using
asn1t.h) with BER indefinite lengths will now be rejected.

Constructed strings are a BER mechanism where a string type can be
represented as a tree of constructed nodes and primitive leaves, that
then have to be concatenated by the parser. This is prohibited in DER
and a significant source of complexity in our parser.
Note this change does not affect our PKCS#7 and PKCS#12 parsers (where
BER is sadly necessary for interop) because those use CBS.
Update-Note: Invalid certificates (and the few external structures using
asn1t.h) with BER constructed strings will now be rejected.

it->funcs is only an ASN1_AUX for ASN1_ITYPE_SEQUENCE and
ASN1_ITYPE_CHOICE. Fortunately, the other possible types for it->funcs
are larger than ASN1_AUX and we don't touch the result when we
shouldn't, so this is merely a strict aliasing violation.

A few can be made static. Move the rest of asn1_locl.h.
Update-Note: Code search says these are unused. If someone's using them,
we can reexport them.

This was used to register custom primitive types, namely some INTEGER
variations. We have since removed them all.

Sadly we need to keep ASN1_put_eoc. Ruby uses it.
OpenSSL's PKCS#7 implementation generated an "ndef" variant of the
encoding functions, to request indefinite-length encoding. Remove the
support code for this.
Update-Note: Types that use one of the NDEF macros in asn1t.h will fail
to compile. This CL should not affect certificate parsing.

This entire function is assuming all the STACK_OF(T) types are secretly
the same type, but best to consistently use the sk_ASN1_VALUE_*
wrappers. The raw sk_foo functions are an implementation detail of the
macros and we probably should rename them to be better prefixed (as
upstream did).
