Support BLKSECDISCARD passthrough for raw host_device backend.
For virtio-blk device:
Add new virtio feature: VIRTIO_BLK_F_SECDISCARD.
Add new virtio command: VIRTIO_BLK_T_SECDISCARD.
Usage:
qemu-system-x86_64 \
... \
-drive
From: Yadong Qi
Add new virtio feature: VIRTIO_BLK_F_SECDISCARD.
Add new virtio command: VIRTIO_BLK_T_SECDISCARD.
This feature is disabled by default, it will check the backend
bs->open_flags & BDRV_O_SECDISCARD, enable it if BDRV_O_SECDISCARD
is supported.

Add a new option "secdiscard" for block drive. Parse it and
record it in bs->open_flags as bit(BDRV_O_SECDISCARD).
Add a new BDRV_REQ_SECDISCARD bit for secure discard request
from virtual device.
For host_device backend: implement by ioctl(BLKSECDISCARD) on
real host block

Add default recovery options for QGA on windows. Previously, QGA
on windows will not try to restart service if it is down. This PS
add some default options for the first, second and other failures,
with an interval of 1min. Failure counter will reset after 1 day.

When we expose an SMC conduit, we're implicitly telling the guest that
there is EL3 available because it needs to call it. While that EL3 then
is not backed by the emulated CPU, from the guest's EL2 point of view,
it still means there is an EL3 to call into.
This is a problem for VMware ESXi,
We currently use a flexible array member for target_dirent,
but use incorrectly fixed length arrays for target_dirent64,
linux_dirent and linux_dirent64.
This requires that we adjust the definition of the VFAT READDIR
ioctls which hard-code the 256 namelen size into the ioctl constant.
Always allocate host storage; this ensures that the struct
is sufficiently aligned for the host. Merge the three host
implementations of getdents via a few ifdefs. Utilize the
same method for do_getdents64.

There are a number of alignement issues flagged up by clang,
this attempts to fix only one of them: getdents.
Changes for v2:
* Do not QEMU_BUILD_BUG_ON for size mismatch,
as this triggers for i386 host.
