Update security/netpgpverify to version 20140202

Changes from previous version:

Add the ability for netpgpverify to verify ssh-pub-key-based signatures.

It is much more likely for ssh (rather than pgp) keys to be available,
and used, as a source of authentication data.  These changes add the
ability for netpgpverify(1) -- the standalone, zero-prereq utility -
to verify signatures made by netpgp when using ssh keys.

Running the regression tests in WRKDIR gives the following output:

A new HOWTO file is provided in the sources (files/HOWTO) to show how
to sign data using ssh keys and netpgp(1).

Update mk-configure to 0.26.0

  "Features" framework was implemented (variable MKC_FEATURES).  In
  general, a feature is something that has problems with
  portability. This may be a function name or header missing on some
  platforms, for example.  What developer needs to do is to add
  FEATURENAME to MKC_FEATURES variable and add #include
  <mkc_FEATURENAME.h> where it is needed. Internally, system
  requiremets are checked in the automatically included
  mkc_imp.f_FEATURENAME.mk file and all required actions (includes,
  define checks etc.)  are made in mkc_FEATURENAME.h header file.
  Currently the following features are provided: strlcat, strlcpy,
  getline, libm, libdl, RB, SPLAY, SLIST, SIMPLEQ, STAILQ, LIST, TAILQ
  and CIRCLEQ. Original idea was stolen from pkgsrc.

  mkc_imp.pkg-config.mk:
    - New variables MKC_CHECK_PKGCONFIG and MKC_REQUIRE_PKGCONFIG were
      introduced.  They work just like other MKC_{CHECK,REQUIRE}_*
      variables from mkc.configure.mk. Thanks to Andrew Shadura for
      pushing me to this direction.

  mkc.configure.mk:
    - MKC_{CHECK,REQUIRE}_PROTOTYPES were introduced.  With their help
      mk-configure is able to check C function prototypes.  This
      feature was proposed by Andrew Shadura.

  If ${MKC_CACHEDIR} does not exit, it is automatically created.

  ${SRCTOP}/Makefile.common is included by all subprojects if it
  exists. It can be used as a replacement or addition for
  ../Makefile.inc.

  Valiables SRCDIR_<dir>, SRC_PATHADD, MKC_SOURCE_DIR, LDFLAGS0 and
  LDADD0 were introduced.

  Wrongly named builtin 'endianess' was renamed to 'endianness'.
  Thanks to Andew Shadura for the report and fix!

  mk-configure itself is now 2-level project.
  This allows me to run an arbitrary regression test like the following
     bmake test-examples/hello_world
  Hurray! :-)

  mkc.subprj.mk:
    - Now it works correctly if NOSUBDIR is not empty.
      Also, NOSUBDIR affects NODEPS and therefore the dependency graph.
    - New target "print-deps" that outputs the dependency graph was
      introduced.

  -O is added to CFLAGS if USE_FORT==yes, seen on Linux/ppc64/gcc

  Documentation: clean-ups, grammar fixes, minor improvements.

  Fix. Some @@ patterns in mk-configure.7 should not be replaced with
  directories. Thanks to Andrew Shadura for the report!

  This release was successfully tested on the following platforms:
  NetBSD-6.1/amd64, FreeBSD-8.3/amd64, OpenBSD-{4.9,5.3}/x86,
  DragonFlyBSD-3.4/x86, Linux/{x86,amd64}, SunOS-5.10/sparc,
  SunOS-5.11/x86.
Updated devel/mk-configure to 0.26.0
Take care for older bmake, tested on old NetBSD 4's make(1).
