568a417224 Enforce a standard header file guard symbol name
Require that all headers are guarded by a symbol named

  LIBVIRT_$FILENAME

where $FILENAME is the uppercased filename, with all characters
outside a-z changed into '_'.

Note we do not use a leading __ because that is technically a
namespace reserved for the toolchain.

600462834f Remove all Author(s): lines from source file headers
In many files there are header comments that contain an Author:
statement, supposedly reflecting who originally wrote the code.
In a large collaborative project like libvirt, any non-trivial
file will have been modified by a large number of different
contributors. IOW, the Author: comments are quickly out of date,
omitting people who have made significant contribitions.

In some places Author: lines have been added despite the person
merely being responsible for creating the file by moving existing
code out of another file. IOW, the Author: lines give an incorrect
record of authorship.

With this all in mind, the comments are useless as a means to identify
who to talk to about code in a particular file. Contributors will always
be better off using 'git log' and 'git blame' if they need to  find the
author of a particular bit of code.

This commit thus deletes all Author: comments from the source and adds
a rule to prevent them reappearing.

The Copyright headers are similarly misleading and inaccurate, however,
we cannot delete these as they have legal meaning, despite being largely
inaccurate. In addition only the copyright holder is permitted to change
their respective copyright statement.

a7424faff0 Force QMP capability probing
Remove the qmpOnly argument of virQEMUCapsNewForBinaryInternal
and instead always assume it's true.

This effectively sets the minimum QEMU version to 1.2.0.

52b7d910b6 qemu: Refresh caps cache after booting a different kernel
Whenever a different kernel is booted, some capabilities related to KVM
(such as CPUID bits) may change. We need to refresh the cache to see the
changes.

b527589d1f qemu: capabilities: force update if the microcode version does not match
A microcode update can cause the CPUID bits to change; an example
from the past was the update that disabled TSX on several Haswell
and Broadwell machines.

Therefore, place microcode version in the virQEMUCaps struct and
XML, and rebuild the cache if the versions do not match.

f366cfed62 qemu: pass only host arch instead of the whole virCaps
This is a preparation for following patches where we switch to
virFileCache for QEMU capabilities cache

The host arch will always remain the same but virCaps may change.  Now
the host arch is stored while creating new qemu capabilities cache.
It removes the need to pass virCaps into virQEMUCapsCache*() functions.

7fb4c471d1 qemu: separate virQEMUCapsInitCached out of virQEMUCapsNewForBinaryInternal
Preparation for switching to virFileCache where there are two callbacks,
one to get a new data and second one to load a cached data.

This also removes virQEMUCapsReset which is no longer required.

4ceac4bf29 tests: Rename VIRT_TEST_* macros to VIR_TEST_*
We use the "vir" prefix pretty consistently in our
APIs, both external and internal, which made these
macros stood out.

f943a28ca8 tests: Add qemucapsprobe helper
Adding new *.replies files for qemucapabilitiestest or updating the
files when libvirt adds an additional QMP command into the probing
process is quite painful. The goal of the new qemucapsprobe command is
to make this process as easy as

    tests/qemucapsprobe /path/to/qemu/binary >caps.replies
