Add SHA512 digests for distfiles for security category

Problems found locating distfiles:
	Package f-prot-antivirus6-fs-bin: missing distfile fp-NetBSD.x86.32-fs-6.2.3.tar.gz
	Package f-prot-antivirus6-ws-bin: missing distfile fp-NetBSD.x86.32-ws-6.2.3.tar.gz
	Package libidea: missing distfile libidea-0.8.2b.tar.gz
	Package openssh: missing distfile openssh-7.1p1-hpn-20150822.diff.bz2
	Package uvscan: missing distfile vlp4510e.tar.Z

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.

Log message:
Update to 1.2.0:

Significant changes since 1.1.6:
* You can now specify "-" as the input file, meaning standard input.
* Lots and lots of code reorganization, including changes to the build system.
* scrypt now consults the hw.memsize sysctl on relevant platforms to figure
out how much memory is available.  (This should help on OS X.)
* scrypt now detects and uses AESNI instructions for encryption/decryption.
* scrypt now detects and uses SSE2 instructions automatically (and thus there
is no longer an --enable-sse2 option to the configure script).

Log message:
Bulk build wants openssl

Log message:
A simple password-based encryption utility is available as a demonstration
of the scrypt key derivation function. On modern hardware and with default
parameters, the cost of cracking the password on a file encrypted by scrypt
enc is approximately 100 billion times more than the cost of cracking the
same password on a file encrypted by openssl enc; this means that a five-
character password using scrypt is stronger than a ten-character password
using openssl
