Provide default values in pre.in for PROG_LIBPATH, PROG_RPATH,
SHLIB_DIRS, SHLIB_RDIRS, and STOBJLISTS so that they don't have to be
specified in the common case.  Rename KRB5_RUN_ENV and KRB5_RUN_VARS
to RUN_SETUP (already the most commonly used name) and RUN_VARS.  Make
sure to use DEFINES for local defines (not DEFS).  Remove some other
unnecessary makefile content.

Instead, use $(BUILDTOP)/plugins as the plugin base for tests.  For
each real plugin module, create a link in the parent directory if
we're doing a shared-library build--so built KDB modules can be found
in plugins/kdb, preauth modules in plugins/preauth, etc..

Add AI_ADDRCONFIG to the hint flags for every invocation of
getaddrinfo which wasn't already using it.  This is often the default
behavior when no hints are specified, but we tend to specify hints a
lot, so we have to say it ourselves.  AI_ADDRCONFIG causes AAAA
lookups to be skipped if the system has no public IPv6 interface
addresses, usually saving a couple of DNS queries per getaddrinfo
call and allowing DNS caching to be much more effective without the
need for negative caching.

verbiage in Makefile.in files.  For correctness of output, every

Add enough static linking support to run the test suite without shared
libraries, to facilitate gcov and other kinds of instrumentation.  The
necessary changes include:

* Undo some of the changes which removed static linking support,
  and cannibalize the defunct krb5_force_static conditional block
  in aclocal.m4.
* Add --enable-static-only configure option.
* For plugins, use a different symbol name for static and dynamic
  builds, via a macro in k5plugin.h.
* Add build machinery for building static libraries for plugins
  (somewhat grotty due to the difference in names).
* Move plugin subdirs earlier in SUBDIRS in src/Makefile.in.
* Make the in-tree KDB5 plugins dependencies of libkdb5 in a static
  build (aclocal.m4 has to know what they are).
* In kdb5.c, cannibalize the broken _KDB5_STATIC_LINK support to
  allow "loading" of statically linked plugin libraries.

Preauth, authdata, locate, and GSSAPI plugins are not handled by this
change, as they are not currently necessary to the test suite.
Supporting GSSAPI plugins may be a bit tricky but the others should be
straightforward if they become needed.

$(STLIBEXT) changes from .a-nobuild to .a in a normal shared build as
a result of these changes (except on AIX where aclocal.m4 changes it).
This does not seem to be important as we avoid selecting the static
library for building via other means.
