bfe7721d50 util: move virFile* functions from virutil.c to virfile.c
These all existed before virfile.c was created, and for some reason
weren't moved.

This is mostly straightfoward, although the syntax rule prohibiting
write() had to be changed to have an exception for virfile.c instead
of virutil.c.

This movement pointed out that there is a function called
virBuildPath(), and another almost identical function called
virFileBuildPath(). They really should be a single function, which
I'll take care of as soon as I figure out what the arglist should look
like.

7c9a2d88cd virutil: Move string related functions to virstring.c
The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.

1732c1c629 Fix parsing of SELinux ranges without a category
Normally libvirtd should run with a SELinux label

  system_u:system_r:virtd_t:s0-s0:c0.c1023

If a user manually runs libvirtd though, it is sometimes
possible to get into a situation where it is running

  system_u:system_r:init_t:s0

The SELinux security driver isn't expecting this and can't
parse the security label since it lacks the ':c0.c1023' part
causing it to complain

  internal error Cannot parse sensitivity level in s0

This updates the parser to cope with this, so if no category
is present, libvirtd will hardcode the equivalent of c0.c1023.

Now this won't work if SELinux is in Enforcing mode, but that's
not an issue, because the user can only get into this problem
if in Permissive mode. This means they can now start VMs in
Permissive mode without hitting that parsing error

dce95297e3 tests: uniformly report test failures
testutils.c likes to print summaries after a test completes,
including if it failed.  But if the test outright exit()s,
this summary is skipped.  Enforce that we return instead of exit.

* cfg.mk (sc_prohibit_exit_in_tests): New syntax check.
* tests/commandhelper.c (main): Fix offenders.
* tests/qemumonitorjsontest.c (mymain): Likewise.
* tests/seclabeltest.c (main): Likewise.
* tests/securityselinuxlabeltest.c (mymain): Likewise.
* tests/securityselinuxtest.c (mymain): Likewise.
* tests/testutils.h (VIRT_TEST_MAIN_PRELOAD): Likewise.
* tests/testutils.c (virtTestMain): Likewise.
(virtTestCaptureProgramOutput): Use symbolic name.

32df483f1d Fix SELinux security label test
If securityselinuxtest was run on a system with newer SELinux
policy it would fail, due to using svirt_tcg_t instead of
svirt_t. Fixing the domain type to be KVM avoids this issue.

9674f2c637 selinux: Use raw contexts
We are currently able to work only with non-translated SELinux
contexts, but we are using functions that work with translated
contexts throughout the code.  This patch swaps all SELinux context
translation relative calls with their raw sisters to avoid parsing
problems.

The problems can be experienced with mcstrans for example.  The
difference is that if you have translations enabled (yum install
mcstrans; service mcstrans start), fgetfilecon_raw() will get you
something like 'system_u:object_r:virt_image_t:s0', whereas
fgetfilecon() will return 'system_u:object_r:virt_image_t:SystemLow'
that we cannot parse.

I was trying to confirm that the _raw variants were here since the dawn of
time, but the only thing I see now is that it was imported together in
the upstream repo [1] from svn, so before 2008.

Thanks Laurent Bigonville for finding this out.

9136032a66 Add test case for SELinux label generation
This test case validates the correct generation of SELinux labels
for VMs, wrt the current process label. Since we can't actually
change the label of the test program process, we create a shared
library libsecurityselinuxhelper.so which overrides the getcon()
and setcon() libselinux.so functions. When started the test case
will check to see if LD_PRELOAD is set, and if not, it will
re-exec() itself setting LD_PRELOAD=libsecurityselinuxhelper.so
