ec3a076c9e util: virtypedparam: Refactor return value of virTypedParamListStealParams
Return the number of parameters via pointer passed as argument to free
up possibility to report errors. Strangely all callers actually use
'int' as type for storing the count of elements, thus this function will
use the same.

The function is also renamed to virTypedParamListSteal.

77d417d9ef Drop checks for virURIFormat() retval
The virURIFormat() function either returns a string, or aborts

8b2bf0f1d7 admin: Introduce virAdmConnectSetDaemonTimeout
Use of the admin APIs to modify logging temporarily has a rather serious
deficiency when the daemon whose config is being changed is using
auto-shutdown (default with socket-activated deployments) as the
configuration is discarded if there is no client or VM/other object
blocking auto shutdown.

This API allows users to disable/postpone shutdown timeout so that the
configuration doesn't change under their hands.

9f6749dea0 util: Check for errors in virLogSetFromEnv
And make callers check the return value as well.  This helps error out early for
invalid environment variables.

That is desirable because it could lead to deadlocks.  This can happen when
resetting logging after fork() reports translated errors because gettext
functions are not reentrant.  Well, it is not limited to resetting logging after
fork(), it can be any translation at that phase, but parsing environment
variables is easy to make fail on purpose to show the result, it can also happen
just due to a typo.

Before this commit it is possible to deadlock the daemon on startup
with something like:

LIBVIRT_LOG_FILTERS='1:*' LIBVIRT_LOG_OUTPUTS=1:stdout libvirtd

where filters are used to enable more logging and hence make the race less rare
and outputs are set to invalid

Combined with the previous patches this changes
the following from:

...
<deadlock>

to:

...
libvirtd: initialisation failed

The error message is improved in future commits and is also possible thanks to
this patch.

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:

mixing these two lead to confusing and easy to miss bugs (see

prefix with autotools, we are free to chose our own prefix with

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.

4a5370ba41 src: rewrite driver name checker in Python
As part of a goal to eliminate Perl from libvirt build tools,
rewrite the check-drivername.pl tool in Python.

This was mostly a straight conversion, manually going line-by-line
to change the syntax from Perl to Python. Thus the overall structure
of the file and approach is the same.

In testing though it was discovered the existing code was broken
since it hadn't been updated after driver.h was split into many
files. Since the old code is being thrown away, the fix was done
as part of the rewrite rather than split into a separate commit.
