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 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:
For clang, don't use the rotate inline asm, but expect the compiler to
generate optimal code.

Log message:
Update HOMEPAGE, which were unknown (MASTER_SITES is still unknown).

Log message:
Remove pkgviews: don't set PKG_INSTALLATION_TYPES in Makefiles.

Log message:
Only 1 package in the tree uses a buildlink dependency on libtomcrypt
(security/dropbear), so bump the BUILDLINK_API_DEPENDS to reflect the
current value of the package.

Log message:
fix makefile.shared so that CFLAGS from the environment are added
bump PKGREV

Log message:
Edited DESCR in the case of:
 File too long (should be no more than 24 lines).
 Line too long (should be no more than 80 characters).
 Trailing empty lines.
 Trailing white-space.
Trucated the long files as best as possible while preserving the most info
contained in them.

Log message:
Drop superfluous PKG_DESTDIR_SUPPORT, "user-destdir" is default these days.

Log message:
build shared lib, bump PKGREV

Import libtomcrypt (version 1.17) into the packages collection.

	LibTomCrypt is a fairly comprehensive, modular and portable
	cryptographic toolkit that provides developers with a vast array of
	well known published block ciphers, one-way hash functions, chaining
	modes, pseudo-random number generators, public key cryptography and a
	plethora of other routines.  LibTomCrypt has been designed from the
	ground up to be very simple to use.  It has a modular and standard API
	that allows new ciphers, hashes and PRNGs to be added or removed
	without change to the overall end application.  It features easy to
	use functions and a complete user manual which has many source snippet
	examples.
