[16] RFR JDK-8172366: Support SHA-3 based signatures

[Jamil Nimeh]

 From just a quick skimming across a few FIPS specs, it looks like DSA 
with SHA-3 seems worth including.  FIPS 202 is designed to supplement 
the hash algs in 180-4, and Section 2.3 of 186-4 indicates that SHAx(M) 
is intended for those algs specified in 180 (and I assume by extension 
202).  Since there are OIDs in the NIST arc for dsa-with-sha3-nnn it 
seems like all the pieces have specification support.  Seems like a good 
thing to do.
