Due to a missing entries in Makefile, we were not distributing
all the systemtap scripts we have.

Some of the examples make use of asprintf and strtol functions (to keep
things simple) which are prohibited to use within our code (enforced by
syntax-check). Therefore besides adding some examples, this patch also updates
cfg.mk to exclude examples directory from asprintf and strtol rules, as well as
updates .gitignore to exclude all the new admin binaries created in the
'examples' dir.

We have this code in our Makefile that tries to remove
/etc/libvirt/nwfilter if directory is left empty after all our
example nwfilters were uninstalled. However, the check for that
is missing quotation marks thus rendering the test useless:

test -z allow-arp.xml allow-dhcp-server.xml .. qemu-announce-self.xml || \
  rmdir "/some/path/libvirt.git/_install/etc/libvirt/nwfilter"
/bin/sh: line 0: test: too many arguments

Avoid forgetting to add the correct fields to the switches in
event-test.

So after da176bf6 and friend we have switched to $(wildcard
some/path/*.xml) instead of enumerating the files explicitly.
This is nice, however it makes distcheck build from VPATH fail.
The reason is that it's is not obvious to what does the wildcard
refer to: srcdir or builddir?

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'
