RFR: 8235710: Remove the legacy elliptic curves

[Anthony Scarpino]

This change removes the native elliptic curves library code; as well as, and calls to that code, tests, and files
associated with those libraries.  The makefiles have been changed to remove from all source builds of the ec code.  The
SunEC system property is removed and java.security configurations changed to reflect the removed curves.

This will remove the following elliptic curves from SunEC:   secp112r1, secp112r2, secp128r1, secp128r2, secp160k1,
secp160r1, secp160r2, secp192k1, secp192r1, secp224k1, secp224r1, secp256k1, sect113r1, sect113r2, sect131r1,
sect131r2, sect163k1, sect163r1, sect163r2, sect193r1, sect193r2, sect233k1, sect233r1, sect239k1, sect283k1,
sect283r1, sect409k1, sect409r1, sect571k1, sect571r1, X9.62 c2tnb191v1, X9.62 c2tnb191v2, X9.62 c2tnb191v3, X9.62
