Looking for feedback on patch for libnetpgpverify:

Remove an item from the TODO list:

+ get rid of calls to snprintf which simply add the returned value to
the number of characters used so far. This practice is unsafe. Instead,
use a dynamic buffer and grow its size to accommodate the contents.

+ Bump version number to 20160214

+ Use the same method as libnetpgpverify for finding the version number
from the sources.

+ add USE_ARG definition to some files which use it but don't check to
see that it's been defined

and second one is to pkg_install:

Let's make a new patch for pkg_install to use SHA512 digests as well as md5

+ add sha3 functionality (from Taylor Campbell) to libnbcompat

+ tag MD5 "checksums" internally within pkg_install as MD5

+ add a combo digest type (sha512 and sha3)
