Add a base class that is common to virtio-gpu and vhost-user-gpu
devices.
The VirtIOGPUBase base class provides common functionalities necessary
for both virtio-gpu and vhost-user-gpu:
- common configuration (max-outputs, initial resolution, flags)
- virtio device initialization, including queue setup
- device pre-conditions checks (iommu)
- migration blocker
- virtio device callbacks
- hooking up to qemu display subsystem
- a few common helper functions to reset the device, retrieve display
informations
- a class callback to unblock the rendering (for GL updates)
What is left to the virtio-gpu subdevice to take care of, in short,
are all the virtio queues handling, command processing and migration.

Add a new vhost-user message to give a unix socket to a vhost-user
backend for GPU display updates.
Back when I started that work, I added a new GPU channel because the
vhost-user protocol wasn't bidirectional. Since then, there is a
vhost-user-slave channel for the slave to send requests to the master.
We could extend it with GPU messages. However, the GPU protocol is
quite orthogonal to vhost-user, thus I chose to have a new dedicated
channel.
See vhost-user-gpu.rst for the protocol details.

Since Linux 2.6 the stat syscalls have mostly supported nanosecond
components for each of the file-related timestamps.
QEMU user mode emulation currently does not pass through the nanosecond
portion of the timestamp, even when the host system fills in the value.
This results in a mismatch when run on subsecond resolution filesystems
such as ext4 or XFS.
An example of this leading to inconsistency is cross-debootstraping a
full desktop root filesystem of Debian Buster. Recent versions of
fontconfig store the full timestamp (instead of just the second portion)
of the directory in its per-directory cache file, and checks this against
the directory to see if the cache is up-to-date. With QEMU user mode
emulation, the timestamp stored is incorrect, and upon booting the rootfs
natively, fontconfig discovers the mismatch, and proceeds to rebuild the
cache on the comparatively slow machine (low-power ARM vs x86). This
stalls the first attempt to open whatever application that incorporates
fontconfig.
This patch renames the "unused" padding trailing each timestamp element
to its nanosecond counterpart name if such an element exists in the
kernel sources for the given platform. Not all do. Then have the syscall
wrapper fill in the nanosecond portion if the host supports it, as
specified by the _POSIX_C_SOURCE and _XOPEN_SOURCE feature macros.
Recent versions of glibc only use stat64 and newfstatat syscalls on
32-bit and 64-bit platforms respectively. The changes in this patch
were tested by directly calling the stat, stat64 and newfstatat syscalls
directly, in addition to the glibc wrapper, on arm and aarch64 little
endian targets.

The ICC_CTLR_EL3 register includes some bits which are aliases
of bits in the ICC_CTLR_EL1(S) and (NS) registers. QEMU chooses
to keep those bits in the cs->icc_ctlr_el1[] struct fields.
Unfortunately a missing '~' in the code to update the bits
in those fields meant that writing to ICC_CTLR_EL3 would corrupt
the ICC_CLTR_EL1 register values.

Please consult the QEMU source for the most up-to-date

Checking the git history, this code was introduced in commit
ac05f34924, very similar to commit 3d3b8303c6 for the
'boot-menu-wait' entry, which explicitely use little-endian.
OVMF consumes 'boot-menu-wait' as little-endian, however it does
not consume 'reboot-timeout'.
Regarding the git history and OVMF use, we choose to explicit
'reboot-timeout' endianess as little-endian.

Currently, fw_cfg_test uses one QTestState for every test case.
This will add all command lines for every test case and
this is unnecessary. This patch split the test cases and for
every test case it uses his own QTestState. This patch does following
things:
1. Get rid of the global 'fw_cfg', this need add a uninit function
2. Convert every test case in a separate QTestState
After this patch, we can add fw_cfg test case freely and will not
have effect on other test cases.
