acf522e85a examples: Avoid gnulib, have standalone examples
Commit 0c6ad476 updated gnulib, which rearranged some of the
conditions in gnulib wrapper headers such that compilation
started failing on BSD systems when the normal system <unistd.h>
tried to include another system header but instead got a
gnulib wrapper header in an incomplete state; this is because
gnulib headers only work if <config.h> is included first.

Commit b6f78259 papered over the symptoms of that by including
<config.h> in all the examples.  But this logic is backwards -
if our examples are truly meant to be stand-alone, they should
NOT depend on how libvirt was configured, and should NOT
depend on the gnulib fixes for system quirks.  In particular,
if an example does not need to link against libgnulib.la,
then it also does not need to use -Ignulib in its compile
flags, and likewise does not need to include <config.h> since
none of the gnulib wrapper headers should be interfering.

So, revert (most of) b6f78259 (except for the bogus pre-patch
use of "config.h" in admin/logging.c: if config.h is included,
it should be via <> rather than "", and must be before any
system headers); then additionally nuke all mention of
<config.h>, -Ignulib, and -llibgnu.la, making all of the
examples truly standalone.

b6f7825992 examples: include config.h
Since gnulib commit 6954995d unistd.h is included via stdlib.h
on BSD systems, which requires config.h to be included first.

Add config.h to the files that use it.

6ee918de74 examples: Remove config.h from hellolibvirt and openauth
These two examples do not use any definition from config.h, and by
removing it these examples can be compiled standalone.

da176bf6b7 examples: Use one top level makefile
Using one Makefile per example subdirectory essentially serializes 'make'
calls. Convert to one example/Makefile that builds and distributes
all the subdir files. This reduces example/ rebuild time from about 5.8
seconds to 1.5 seconds on my machine.

One slight difference is that we no longer ship Makefile.am with the
examples in the rpm. This was virtually useless anyways since the Makefile
was very specific to libvirt infrastructure, so wasn't generically
reusable anyways.

Tested with 'make distcheck' and 'make rpm'

3e2f27e13b Don't link virt-login-shell against libvirt.so (CVE-2013-4400)
The libvirt.so library has far too many library deps to allow
linking against it from setuid programs. Those libraries can
do stuff in __attribute__((constructor) functions which is
not setuid safe.

The virt-login-shell needs to link directly against individual
files that it uses, with all library deps turned off except
for libxml2 and libselinux.

Create a libvirt-setuid-rpc-client.la library which is linked
to by virt-login-shell. A config-post.h file allows this library
to disable all external deps except libselinux and libxml2.

d7f53c7b97 maint: use LGPL correctly
Several files called out COPYING or COPYING.LIB instead of using
the normal boilerplate.  It's especially important that we don't
call out COPYING from an LGPL file, since COPYING is traditionally
used for the GPL.  A few files were lacking copyright altogether.

builddir before srcdir.
