Update netpgpverify to version 20141204

Changes since 20141129:

+ bring over lint changes from src/crypto version of this utility
+ add a helper function to get an element from a cursor
+ added a small compile and test script, which uses BSD makefiles
+ change WARNS level in BSD Makefile from 6 to 5 - changes to make
  WARNS=6 compile are way too intrusive and distracting to be useful
