Currently we mishandle emulation of the getdents syscall for the
case of a 64 bit guest on a 32 bit host -- it defaults into
the 'host and guest same size' codepath and generates incorrect
structures in the guest buffer.

We can't easily handle the 64-on-32 case using the host getdents
syscall, because the guest struct dirent is bigger than the
host struct dirent, and we might find the host syscall has handed
us back more records than we can fit in the guest buffer after
conversion. Instead, always emulate 64-on-32 getdents with
the host getdents64. This avoids the buffer-overrun problem
because a dirent64 struct is always the same size on any host
and always larger than any architecture's dirent struct.

As support for RISC-V was only merged into the mainline kernel at 4.15
it is unlikely that glibc will be happy with a reported kernel version

Sid compiler the tests failed with:

  FATAL: kernel too old

Bump the version to the minimum a RISC-V glibc would expect:

stuff that's accumulated during the 2.12 freeze.  Highlights are:

    * Many improvements for the Uninorth PCI host bridge for Mac
      machine types
    * Preliminary helpers improve handling of multiple backing
      pagesizes (not strictly ppc related, but have acks and aimed to
      allow future ppc changes)
    * Cleanups to pseries cpu initialization
    * Cleanups to hash64 MMU handling
    * Assorted bugfixes and improvements

During guest OS reboot, guest framebuffer is invalid. It will cause
bugs, if the invalid guest framebuffer is still used by host.

This patch is to introduce vfio_display_reset which is invoked
during vfio display reset. This vfio_display_reset function is used
to release the invalid display resource, disable scanout mode and
replace the invalid surface with QemuConsole's DisplaySurafce.

This patch can fix the GPU hang issue caused by gd_egl_draw during
guest OS reboot.

Changes v3->v4:
 - Move dma-buf based display check into the vfio_display_reset().
   (Gerd)

Changes v2->v3:
 - Limit vfio_display_reset to dma-buf based vfio display. (Gerd)

Changes v1->v2:
 - Use dpy_gfx_update_full() update screen after reset. (Gerd)
 - Remove dpy_gfx_switch_surface(). (Gerd)

When trying to build with latest libcacard-2.5.1, I hit the
following error:

In file included from hw/usb/ccid-card-passthru.c:12:0:
/usr/include/cacard/vscard_common.h:26:2: error: #warning "Only <libcacard.h> can be included directly" [-Werror=cpp]
 #warning "Only <libcacard.h> can be included directly"

While it was fixed in libcacard upstream (so that individual
files can be included directly), it doesn't make much sense.
Let's switch to including the main libcacard.h and also require
at least libcacard-2.5.1 which introduced it. It's available
since late 2015.
