Subject: [PATCH 1/5] pkey: simplify ossl_pkey_new()
ossl_{rsa,dsa,dh,ec}_new() called from this function are not used
anywhere else. Inline them into pkey_new0() and reduce code
duplication.

Subject: [PATCH 2/5] pkey: inline {rsa,dsa,dh,ec}_instance()
Merge the code into the callers so that the wrapping Ruby object is
allocated before the raw key object is allocated. This prevents possible
memory leak on Ruby object allocation failure, and also reduces the
lines of code.

Subject: [PATCH 5/5] pkey: refactor #export/#to_pem and #to_der
Add ossl_pkey_export_traditional() and ossl_pkey_export_spki() helper
functions, and use them. This reduces code duplication.
