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:

ccc6dd8f11 virtlo(g|ck)d: Fix exec-restart
Commit 94e45d1042 broke exec-restart of virtlogd and virtlockd as the
code waiting for the daemon shutdown closed the daemons before
exec-restarting.

Generated using the following spatch:

However, 14 occurrences were not replaced, e.g. in

6938cd8830 logging: allow max_len=0 to disable log rollover
Currently setting max_len=0 causes virtlogd to spin in a busy loop. It
is natural to allow this to disable log rollover which can be useful for
developers debugging things.

Note disabling rollover exposes the host to denial of service from a
malicious guest, so must be used with care.

e72a4a7f01 src/meson: add missing augeas tests
Most of our augeas files are generated during meson setup into build
directory and we were running augeas tests only for these files.

However, we have some other augeas and config files that are not
modified during meson setup and they are only in source directories.
In order to run tests for these files we need to provide different path
to both source and build directories.

d7147b3797 m4: virt-xdr: rewrite XDR check
The current code to check XDR support was obsolete and way to
complicated.

On linux we can use pkg-config to check for libtirpc and have
the CFLAGS and LIBS configured by it as well.

On MinGW there is portablexdr library which installs header files
directly into system include directory.

On FreeBSD and macOS XDR functions are part of libc so there is
no library needed, we just need to call AM_CONDITIONAL to silence
configure which otherwise complains about missing WITH_XDR.

a1c793ec57 daemons: Support --timeout 0
When using systemd we want to take advantage of socket activation
instead of keeping daemons running all the time, so we default to
shutting them down after two minutes of inactivity.

At the same time, we want it to be possible for the admin to opt
out of this behavior and disable timeouts entirely. A very natural
way to do so would be to specify a zero-length timeout, but that's
currently not accepted by the command line parser. Address that.
