Remove an item from the netpgpverify/libnetpgpverify 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.

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

pkgsrc changes:

+ Bump version number to 20160214

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