I have tried to convert 'len' type variable declarations to unsigned as a
means to address these warnings when appropriate, but when in doubt I have
used casts in the comparisons instead. The better solution (that would get
us all lynched by API users) would be to go through and convert all the
function prototypes and structure definitions to use unsigned variables
except when signed is necessary. The proliferation of (signed) "int" for
strictly non-negative uses is unfortunate.

EVP_PKEY_cmp_parameters() returned 0, otherwise it should
go on processing the public key component.  Thia has nothing
to do with the proper handling of EC parameters or not.

Have EVP_PKEY_cmp() call EVP_PKEY_cmp_parameters(), and make a note
about the lack of parameter comparison for EC.
