Document error behavior of various functions

- Document error behavior of:
  - EVP_PKEY_assign_XXX
  - EVP_PKEY_set1_XXX
  - EVP_PKEY_assign
  - EVP_PKEY_set_type
  - EC_GROUP_new_by_curve_name
  - EC_KEY_set_group
  - ECDSA_size
  - HMAC_Final
- Document that EVP_parse_public_key sets the curve for EC keys
