{
Unwind M_ASN1_* macros for primitive types. At one point in the SSLeay days, all the ASN1_STRING typedefs were separate structs (but only in debug builds) and the M_ASN1_* macros included type casts to handle this. This is long gone, but we still have the M_ASN1_* macros. Remove the casts and switch code within the library to call the macros. Some subtleties: - The "MSTRING" types (what OpenSSL calls its built-in CHOICEs containing some set of string types) are weird because the M_FOO_new() macro and the tasn_new.c FOO_new() function behave differently. I've split those into a separate CL. - ASN1_STRING_type, etc., call into the macro, which accesses the field directly. This CL inverts the dependency. - ASN1_INTEGER_new and ASN1_INTEGER_free, etc., are generated via IMPLEMENT_ASN1_STRING_FUNCTIONS in tasn_typ.c. I've pointed M_ASN1_INTEGER_new and M_ASN1_INTEGER_free to these fields. (The free function is a no-op, but consistent.) - The other macros like M_ASN1_BIT_STRING_dup largely do not have corresponding functions. I've aligned with OpenSSL in just using the generic ASN1_STRING_dup function. But some others, like M_ASN1_OCTET_STRING_dup have a corresponding ASN1_OCTET_STRING_dup function. OpenSSL retained these, so I have too. Update-Note: Some external code uses the M_ASN1_* macros. This should remain compatible, but some type errors may have gotten through unnoticed. This CL restores type-checking.
