Remove DSA write_params.
This imports upstream's ea6b07b54c1f8fc2275a121cdda071e2df7bd6c1 along
with a bugfix in 987157f6f63fa70dbeffca3c8bc62f26e9767ff2.
In an SPKI, a DSA key is only an INTEGER, with the group information in
the AlgorithmIdentifier. But a standalone DSAPublicKey is more complex
(and apparently made up by OpenSSL). OpenSSL implemented this with a
write_params boolean and making DSAPublicKey a CHOICE.
Instead, have p_dsa_asn1.c encode an INTEGER directly. d2i_DSAPublicKey
only parses the standalone form. (That code will be replaced later, but
first do this in preparation for rewriting the DSA ASN.1 code.)
