There is some magic going on when it comes to stat() or lstat().
Basically, stat() can either be a regular function, an inline
function that calls __xstat(_STAT_VER, ...) or a macro that does
the same as the inline func. Don't ask why is that, just read the
documentation in sys/stat.h and make sure you have a bucket next
to you. Anyway, currently there will not be both stat and __xstat
symbols at the same time, as one of them gets overwritten to the
other one during compilation. But this is not true anymore once
we start chaining our mocking libraries. Therefore we need a
wrapper that calls desired function from glibc.

Some of the test configuration files in tests/xlconfigdata
use the old qemu-dm as the emulator. Many of the configuration
features tested (spice, rbd, multi-usb) are not even usable with
the old qemu. Change these files to use the new qemu-xen (also
known as qemu upstream) emulator.
Note: This change fixes xlconfigtest failures when the old
qemu is actually installed on the system. During device post
parse, the libxl driver attempts to invoke the emulator to
determine if it is the old or new qemu so it can properly set
video RAM defaults. With the old qemu installed, the default
video RAM was set differently than the expected value.
Changing all the test data files to use qemu-xen ensures
predictable results wrt default video RAM size.

When probing the <emulator> with '-help' to determine if
it is the old qemu, errors are reported if the emulator
doesn't exist
libvirt: error : internal error: Child process
(/usr/lib/xen/bin/qemu-dm -help) unexpected exit status 127:
libvirt: error : cannot execute binary /usr/lib/xen/bin/qemu-dm:
No such file or directory
Avoid the probe if the specified emulator doesn't exist,
squelching the error. There is no behavior change since
libxlDomainGetEmulatorType() would return
LIBXL_DEVICE_MODEL_VERSION_QEMU_XEN if the probe failed
via virCommandRun().

Further followup discussions in list on commit 192a53e concluded
that we should be leaving out the USB controller only for
i440fx machines as default USB can be used by someone on q35
at random slots.

Move filling out the default video (v)ram to DeviceDefPostParse.
This means it can be removed from virDomainVideoDefParseXML
and qemuParseCommandLine. Also, we no longer need to special case
VIR_DOMAIN_VIRT_XEN, since the per-driver callback gets called
before the generic one.
Commit 6879be48 moved adding of an implicit video device after XML
parsing. As a result, libxlDomainDeviceDefPostParse() is no longer
called to set the default vram when adding an implicit device.
Commit 6879be48 assumes virDomainVideoDefaultRAM() will set the
default vram, but it returns 0 if the domain virtType is
VIR_DOMAIN_VIRT_XEN. Attempting to start an HVM domain with vram=0
results in
error: unsupported configuration: videoram must be at least 4MB for CIRRUS
The default vram setting for Xen HVM domains depends on the device
model used (qemu-xen vs qemu-traditional), hence setting the
default is deferred to libxlDomainDeviceDefPostParse().
Call the device post-parse callback even for implicit video,
to fill out the default vram even for VIR_DOMAIN_VIRT_XEN.

Both virGetLastError and virGetLastErrorMessage call virLastErrorObject method
that returns a thread-local error object. However, if a direct call to malloc
or pthread_setspecific (probably also due to malloc, since it sets ENOMEM)
fail, virLastErrorObject returns NULL which, although incorrectly interpreted
by virGetLastError as no error, still requires the caller to check for NULL
pointer. This isn't the case with virGetLastErrorMessage that also treated it
incorrectly as no error, but returned the literal "no error".
This patch tweaks the checks in the virGetLastErrorMessage function, so that
if virLastErrorObject failed, it returned "unknown error" which is equivalent
to the current approach with virGetLastError and if it returned NULL,
"unknown error" was set.

We were adding a sheepdog requirement at runtime, but forgetting

The %changelog entries in the RPM are just a poor immitation
of the release notes, which is not what %changelog section
is for. It should be reflecting changes in the RPM packaging,
not changes in the application releases. Further, this bogus
list of changes has to be manually deleted every time we sync
the RPM with Fedora. Remove them, since they serve no useful
purpose.

Rather than letting the configure script auto-detect features
we expect, use --with-xxx to explicitly mandate them. This
ensures that we get an error upfront when running configure,
rather than a failure later during build or RPM file packaging
time.
