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:

e154e01ead util: buffer: Simplify handling of indent overflows
Rather than setting usage error truncate the indentation level. Having
the output string misformated is way more useful to figure out where the
error lies rather than reporting an error after a giant formatter
function.

In testBufAutoIndent we now validate that the indentation is truncated
and testBufAddBuffer2 is removed since it became bogus.
