qemu_hotplugpriv.h is a header file created to share a global variable
called 'qemuDomainRemoveDeviceWaitTime', declared in qemu_hotplug.c,
to other files that would want to change the timeout value
(currently, only tests/qemuhotplugtest.c).
Previous patch deprecated the variable, using qemu_driver->unplugTimeout
to set the timeout instead. This means that the header file is now
unused, and can be safely discarded.

For some architectures and setups, device removal can take
longer than the default 5 seconds. This results in commands
such as 'virsh setvcpus' to fire timeout messages even if
the operation were successful in the guest, confusing the
user.
This patch sets a new 10 seconds unplug timeout for PPC64
guests. All other archs will keep the default 5 seconds
timeout.
Instead of putting 'if PPC64' conditionals inside qemu_hotplug.c
to set the new timeout value, a new function called
qemuDomainGetUnplugTimeout was added. The timeout value is then
retrieved when needed, by passing the correspondent DomainDef
object. This approach allows for different guest architectures
to have distint unplug timeout intervals, regardless of the
host architecture. This design also makes it easier to
modify/enhance the unplug timeout logic in the future
(allow for special timeouts for TCG domains, for example).
A new mock file was created to work with qemuhotplugtest.c,
given that the test timeout is significantly shorter than
the actual timeout value in qemu_hotplug.c.
The now unused 'qemuDomainRemoveDeviceWaitTime' global can't
be simply erased from qemu_hotplug.c though. Next patch will
remove it properly.

The pconfig feature was enabled in QEMU by accident in 3.1.0. All other
newer versions do not support it and it was removed from the
Icelake-Server CPU model in QEMU.
We don't normally change our CPU models even when QEMU does so to avoid
breaking migrations between different versions of libvirt. But we can
safely do so in this specific case. QEMU never supported enabling
pconfig so any domain which was able to start has pconfig disabled.
With a small compatibility hack which explicitly disables pconfig when
CPU model equals Icelake-Server in migratable domain definition, only
one migration scenario stays broken (and there's nothing we can do about
it): from any host to a host with libvirt < 5.10.0 and QEMU > 3.1.0.

Reviewed-by: Ján Tomko <jtomko@redhat.com>
According to rfc3986:
2.3. Unreserved Characters
Characters that are allowed in a URI but do not have a reserved
purpose are called unreserved. These include uppercase and lowercase
letters, decimal digits, hyphen, period, underscore, and tilde.
unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"
URIs that differ in the replacement of an unreserved character with
its corresponding percent-encoded US-ASCII octet are equivalent: they
identify the same resource. However, URI comparison implementations
do not always perform normalization prior to comparison (see Section
6). For consistency, percent-encoded octets in the ranges of ALPHA
(%41-%5A and %61-%7A), DIGIT (%30-%39), hyphen (%2D), period (%2E),
underscore (%5F), or tilde (%7E) should not be created by URI
producers and, when found in a URI, should be decoded to their
corresponding unreserved characters by URI normalizers.
Thus we must not include few other characters which don't match
c_isalpha to conform to the rules.

Allow stack traces to be included with log messages
Sometimes it is useful to see the callpath for log messages.
This change enhances the log filter syntax so that stack traces
can be show by setting '1:+NAME' instead of '1:NAME'.
With the huge & ever increasing number of logging statements per file,
this will be incredibly verbose and have a major performance penalty.
This makes the feature impractical to use widely and as such it is not
worth the code maint cost.
Removing this seldom used feature allows us to drop the 'execinfo'
module in gnulib which provides the backtrace() function which doesn't
exist on non-Linux.

or systemtap for live tracing with minimal perf impact.

In upcoming commits, virSecurityManagerSetAllLabel() will perform
rollback in case of failure by calling
virSecurityManagerRestoreAllLabel(). But in order to do that, the
former needs to have @migrated argument so that it can be passed
to the latter.

The usleep function was missing on older mingw versions, but we can rely
on it existing everywhere these days. It may only support times upto 1
second in duration though, so we'll prefer to use g_usleep instead.
The commandhelper program is not changed since that can't link to glib.
Fortunately it doesn't need to build on Windows platforms either.

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().

Converting from virObject to GObject is reasonably straightforward,
as illustrated by this patch for virIdentity
In the header file
- Remove
typedef struct _virIdentity virIdentity
- Add
#define VIR_TYPE_IDENTITY virIdentity_get_type ()
G_DECLARE_FINAL_TYPE (virIdentity, vir_identity, VIR, IDENTITY, GObject);
Which provides the typedef we just removed, and class
declaration boilerplate and various other constants/macros.
In the source file
- Change 'virObject parent' to 'GObject parent' in the struct
- Remove the virClass variable and its initializing call
- Add
G_DEFINE_TYPE(virIdentity, vir_identity, G_TYPE_OBJECT)
which declares the instance & class constructor functions
- Add an impl of the instance & class constructors
wiring up the finalize method to point to our dispose impl
In all files
- Replace VIR_AUTOUNREF(virIdentityPtr) with g_autoptr(virIdentity)
- Replace virObjectRef/Unref with g_object_ref/unref. Note
the latter functions do *NOT* accept a NULL object where as
libvirt's do. If you replace g_object_unref with g_clear_object
it is NULL safe, but also clears the pointer.

Add the main glib.h to internal.h so that all common code can use it.
Historically glib allowed applications to register an alternative
memory allocator, so mixing g_malloc/g_free with malloc/free was not
safe.
This was feature was dropped in 2.46.0 with:

Deprecate and drop support for memory vtables
Applications are still encourged to match g_malloc/g_free, but it is no
longer a mandatory requirement for correctness, just stylistic. This is
explicitly clarified in

gmem: clarify that g_malloc always uses the system allocator
Applications can still use custom allocators in general, but they must
do this by linking to a library that replaces the core malloc/free
implemenentation entirely, instead of via a glib specific call.
This means that libvirt does not need to be concerned about use of
g_malloc/g_free causing an ABI change in the public libary, and can
avoid memory copying when talking to external libraries.
This patch probes for glib, which provides the foundation layer with
a collection of data structures, helper APIs, and platform portability
logic.
Later patches will introduce linkage to gobject which provides the
object type system, built on glib, and gio which providing objects
for various interesting tasks, most notably including DBus client
and server support and portable sockets APIs, but much more too.
