fb81a56f32 tests: Add hostcpudata for machine with CPU clusters
The data is taken from an HPE Apollo 70 machine, which uses
aarch64 CPUs. It is interesting for us because non-dummy
information about CPU clusters is exposed through sysfs.

In order to keep things reasonable, the data was manually
modified so that only 8 of the original 224 CPUs are included.
Care has been taken to ensure that the topology is otherwise
unaltered.

b20a5e9a4d lib: use struct zero initializer instead of memset
This is a more concise approach and guarantees there is
no time window where the struct is uninitialized.

Generated using the following semantic patch:

  @@
  type T;
  identifier X;

  -  T X;

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:

a551dd5fdf hostcpu: Introduce virHostCPUGetSignature
The purpose of this function is to give a short description that would
be change when a host CPU is replaced with a different model. This is
currently implemented by reading /proc/cpuinfo.

It should be implemented for all architectures for which the QEMU driver
stores host CPU data in the capabilities cache. In other words for archs
that support host-model CPUs.

75a4ec42f7 util: virhostcpu: Fail when fetching CPU Stats for invalid cpu
virHostCPUGetStatsLinux walks through every cpu in /proc/stat until it
finds cpu%cpuNum that matches with the requested cpu.
If none is found it logs the error but it should return -1, instead of 0.
Otherwise virsh nodecpustats --cpu <invalid cpu number> and API bindings
don't fail properly, printing a blank line instead of an error message.

This patch also includes an additional test for virhostcputest to avoid
this regression to happen again in the future.

0169f5ecde tests: add host CPU data files for validating die_id
Only Cascadelake-AP CPUs appear to report "die_id" values != 0 on Linux
right now - AMD EPYC's don't report "die_id" (at least with Fedora 31
kernel). Lacking access to Cascadelake-AP CPUs, this test data was from
a Fedora 31 QEMU guest launched with

 -cpu qemu64 -smp sockets=2,dies=3,cores=2,threads=1

Ideally we'd replace this data with some from a real machine reporting
"die_id", to ensure we're not mislead by QEMU's impl.

c4d18e8b3e util: replace strerror/strerror_r with g_strerror
g_strerror is offers the safety/correctness benefits of strerror_r, with
the API design convenience of strerror.

Use of virStrerror should be eliminated through the codebase in favour
of g_strerror.

commandhelper.c is a special case as its a tiny single threaded test
program, not linked to glib, so it just uses traditional strerror().

There is an inconsistency with VIR_TEST_DEBUG() calls. One half
(roughly) of calls does have the newline character the other one
doesn't. Well, it doesn't have it because it assumed blindly that
new line will be printed, which is not the case.

While at it, introduce VIR_TEST_MOCK macros that makes path out of mock
name to be used with VIR_TEST_PRELOAD or VIR_TEST_MAIN_PRELOAD.  That,
hopefully, improves readability, reduces line length and allows to
tailor VIR_TEST_MOCK for specific platform if it has shared library
suffix different from ".so".

4cfd709021 Fix many mistakes & inconsistencies in header file layout
This introduces a syntax-check script that validates header files use a
common layout:

  /*
   ...copyright header...
   */
  <one blank line>
  #ifndef SYMBOL
  # define SYMBOL
  ....content....
  #endif /* SYMBOL */

For any file ending priv.h, before the #ifndef, we will require a
guard to prevent bogus imports:

  #ifndef SYMBOL_ALLOW
  # error ....
  #endif /* SYMBOL_ALLOW */
  <one blank line>

The many mistakes this script identifies are then fixed.

exception is sanlock which expects the application to include <stdint.h>
before sanlock's headers, because sanlock prototypes use fixed width
int, but they don't include stdint.h themselves, so we have to leave
