7db8373e08 Use G_N_ELEMENTS() more
In a few places we still use the good old:

  sizeof(var) / sizeof(var[0])
  sizeof(var) / sizeof(int)

The G_N_ELEMENTS() macro is preferred though. In a few places we
don't link with glib, so provide the macro definition.

5d99b157bc tests: Return EXIT_FAILURE/EXIT_SUCCESS instead of -1/0
When using VIR_TEST_MAIN() or VIR_TEST_MAIN_PRELOAD() macros, the
retval of mymain() will become retval of main(). Hence, mymain()
should use EXIT_FAILURE and EXIT_SUCCESS return values for
greater portability. Another reason is that otherwise our summary
printing of failed tests doesn't work (see following commit for
more info).

c8238579fb lib: Drop internal virXXXPtr typedefs
Historically, we declared pointer type to our types:

  typedef struct _virXXX virXXX;
  typedef virXXX *virXXXPtr;

But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:

3f3f74dbc7 tests: Fix logic to not have possible NULL deref
It's possible that virBitmapNewString returns NULL with an error
string (and not an allocation failure that would abort); however, if
virBitmapToString is called with a NULL @bitmap, then it will fail
in an ugly manner. So rather than have if (!map && !str) logic, split
the checks for each variable.
