All of the ones being removed are pulled in by internal.h. The only
exception is sanlock which expects the application to include <stdint.h>
before sanlock's headers, because sanlock prototypes use fixed width
int, but they don't include stdint.h themselves, so we have to leave
that one in place.

It doesn't really make sense for us to have stdlib.h and string.h but
not stdio.h in the internal.h header.

Commit 93ec384 was tested on mingw, but broke the build on Linux:
CCLD shunloadtest
shunloadtest.o: In function `main':
/home/eblake/libvirt/tests/shunloadtest.c:106: undefined reference to `virFilePrintf'
...
ssh.o: In function `main':
/home/eblake/libvirt/tests/ssh.c:43: undefined reference to `virFilePrintf'
/home/eblake/libvirt/tests/ssh.c:49: undefined reference to `virFilePrintf'
* tests/testutils.h (fprintf): Provide escape hatch.
* tests/shunloadtest.c: Use it.
* tests/ssh.c: Likewise.

The shunloadStart function didn't check the status of virInitialize which
was flagged by Coverity. Adjust the function and shunloadtest in order
to handle the situation.
https://www.gnu.org/licenses/gpl-howto.html recommends that
the 'If not, see <url>.' phrase be a separate sentence.
* tests/securityselinuxhelper.c: Remove doubled line.
* tests/securityselinuxtest.c: Likewise.
* globally: s/; If/. If/
Per the FSF address could be changed from time to time, and GNU
recommends the following now: (http://www.gnu.org/licenses/gpl-howto.html)
You should have received a copy of the GNU General Public License

This patch removes the explicit FSF address, and uses above instead
(of course, with inserting 'Lesser' before 'General').
Except a bunch of files for security driver, all others are changed
automatically, the copyright for securify files are not complete,
that's why to do it manually:
src/security/security_selinux.h
src/security/security_driver.h
src/security/security_selinux.c
src/security/security_apparmor.h
src/security/security_apparmor.c
src/security/security_driver.c
For unknown reasons, the shunloadtest will crash on Fedora 16
inside dlopen()

Changing from RTLD_NOW to RTLD_LAZY avoids this problem,
but quite possibly does not fix the root cause.
* shunloadtest.c: s/NOW/LAZY/
When libvirt calls virInitialize it creates a thread local
for the virErrorPtr storage, and registers a callback to
cleanup memory when a thread exits. When libvirt is dlclose()d
or otherwise made non-resident, the callback function is
removed from memory, but the thread local may still exist
and if a thread later exists, it will invoke the callback
and SEGV. There may also be other thread locals with callbacks
pointing to libvirt code, so it is in general never safe to
unload libvirt.so from memory once initialized.
To allow dlclose() to succeed, but keep libvirt.so resident
in memory, link with '-z nodelete'. This issue was first
found with the libvirt CIM provider, but can potentially
hit many of the dynamic language bindings which all ultimately
involve dlopen() in some way, either on libvirt.so itself,
or on the glue code for the binding which in turns links
to libvirt
* configure.ac, src/Makefile.am: Ensure libvirt.so is linked
with -z nodelete
* cfg.mk, .gitignore, tests/Makefile.am, tests/shunloadhelper.c,
tests/shunloadtest.c: A test case to unload libvirt while
a thread is still running.
