Update netpgpverify and libnetpgpverify to version 20131219

Fix a call to mp_radix_size to use a pointer to the BIGNUM, not the
address of the pointer, when accessing.  Fixes a problem observed in
other software when using the same code.  The problem was obscured
from the compiler because of the use of __UNCONST().  This makes the
BN_dec2bn() and BN_hex2bn() functions (in libnetpgpverify) work
properly.

OK: wiz
