Add kernel_irqchip=split/on to the QEMU command line
and a capability that looks for it in query-command-line-options
output. For the 'split' option, use a version check
since it cannot be reasonably probed.

Add a new <ioapic> element with a driver attribute.
Possible values are qemu and kvm. With 'qemu', the I/O

There should be no need to make dir based pools world/group readable.
So use 0711, not 0755, as the default perms for storage dirs.
Updates in v2:
- adapt commit wording to mention dropping group readable as well

The regular spec file contains code to deal with the fact
that maintenance releases are uploaded to their own

possible to build maintenance releases there as well.
This also switches the source URL from FTP to HTTP for
consistency with the main spec file.

The Win32 platform can not do link time overrides in the same way
that we can on POSIX / ELF based platforms, so we cannot build
the virfilewrapper.c code reliably. Just stub it out on Win32
so it is a no-op. Tests that use this file are already written
to skip on Win32.

GCC complains that inlining virStringTrimOptionalNewline is not
likely on some platforms:
cc1: warnings being treated as errors
../../src/util/virfile.c: In function 'virFileReadValueBitmap':

../../src/util/virfile.c:3987: error: called from here [-Winline]
Inlining this function is not going to be a measurable performance
benefit either, since the time required to execute it is going to
be dominated by running of strlen() over the string, not by the
function call overhead.

It is no longer needed thanks to the great virfilewrapper.c. And this
way we don't have to add a new set of functions for each prefixed
path.
While on that, add two functions that weren't there before, string and
scaled integer reading ones. Also increase the length of the string
being read by one to accompany for the optional newline at the
end (i.e. change INT_STRLEN_BOUND to INT_BUFSIZE_BOUND).

This mock (which is actually not mock at all, see later) can redirect
all accesses to a path into another path. There is no need to
create mocks for particular directories, you just create a directory
with all the data a redirect the test there.
In the future, this should also be able to register callbacks for
calls/paths, e.g. when the test is going to write into anything under
"/sys/devices", call function fce(); Then in the open() call we would
add information about the fd into some structure and in write() we
would call fce() with parameters like @path to write to, @data to
be written and pointer to optional return value, so that fce() itself
could stop the call from happening or change its behaviour. But
that's an idea for a latter day.
This is not a mock because it will not be preloaded, but compiled in
the test itself. See future patches for usage.

So, because mingw is somehow OK with dereferencing a pointer within a
VIR_DEBUG macro, compared to outside of it to which it complained with a
"potential NULL pointer dereference" error (still a false positive), we
can make the code a tiny bit cleaner.

A previous commit changed the spec to use librbd1-devel on
RHEL-7, since this replaces ceph-devel from RHEL-6:
commit 6cfc8834c8
Author: Peter Krempa <pkrempa@redhat.com>
Date: Thu Mar 5 11:40:54 2015 +0100
spec: Enable RBD storage driver in RHEL-7
Use correct package names too as they differ.
RHEL-7 inherited this rename from Fedora though, so it should
have also made Fedora use the new names.
This was missed, because Fedora still provides a (deprecated)
back-compat RPM for ceph-devel that just pulls in librbd1-devel
(and others).
Fixing this stops libvirt pulling Java into the build root in
Fedora.

The API docs extractor, ESX code generator and keycodemapdb tools
rely on python. Historically every platform that this present, but
with switch to Python3 by default, we're increasingly seeing
installs without a /usr/bin/python.
This tightens up the check during configure, so it exits immediately
if python is missing, rather than leaving an empty $(PYTHON) make
variable which leads to more obscure errors later.
Also add it as a build dep for Mingw, since Fedora build roots no
longer get python2 by default. This was not previously a major
problem, since both ESX & API generated files were included in
EXTRA_DIST, but the keycodemapdb generated files are not, so we
require python all the time now.

After bdcf6e481 there is a crasher in libvirt. The commit assumes
that priv->perf is always set. That is not true. For inactive
domains, the priv->perf is not allocated as it is set in
qemuProcessLaunch(). Now, usually we differentiate between
accesses to inactive and active definition and it works just
fine. Except for 'domstats'. There priv->perf is accessed without
prior check for domain inactivity. While we could check for that,
more robust solution is to make virPerfEventIsEnabled() accept
NULL.
How to reproduce:
1) ensure you have at least one inactive domain
2) virsh domstats

The problem resides in virHostdevUpdateActiveMediatedDevices which gets
called during qemuProcessReconnect. The issue here is that
virMediatedDeviceListAdd takes a pointer to the item to be added to the
list to which VIR_APPEND_ELEMENT is used, which also clears the pointer.
However, in this case only the local copy of the pointer got cleared,
leaving the original pointing to valid memory. To sum it up, during
cleanup phase, the original pointer is freed and the daemon crashes
basically any time it would access it.
