Before commit 49afbca3b0 ("virtio-gpu: drop
use_virgl_renderer"), use_virgl_renderer was preventing calling GL
functions from non-GL context threads. The innocuously looking
g->parent_obj.use_virgl_renderer = false;
was set the first time virtio_gpu_gl_reset() was called, during
pc_machine_reset() in the main thread. Further virtio_gpu_gl_reset()
calls in IO threads, without associated GL context, were thus skipping
GL calls and avoided warnings or crashes (see also
https://gitlab.freedesktop.org/virgl/virglrenderer/-/issues/226).

be distinguished in the caller.

The highest VBE_DISPI_INDEX_ID version supported by QEMU is
VBE_DISPI_ID5. But currently QEMU only allows writing values up to
VBE_DISPI_ID4 to the VBE_DISPI_INDEX_ID register.
As a result of this when a lower version is written to this register and
later VBE_DISPI_ID5 is written back, reads from the register will
continue to report the lower version.
Indeed SeaBIOS is doing that during VGA initialization which causes
guests to always read VBE_DISPI_ID0 instead of the correct version.

Add helper functions to create a dmabuf for a resource and mmap it.
Also, introduce the fields blob and blob_size so that these helpers
can start to use them but the full picture will emerge only after
adding create_blob API in patch 8 of this series.
To be able to create a dmabuf using the udmabuf driver, Qemu needs
to be lauched with the memfd memory backend like this:
qemu-system-x86_64 -m 8192m -object memory-backend-memfd,id=mem1,size=8192M
-machine memory-backend=mem1

request can't be mapped in one go, for example due to a iommu creating
a linear dma mapping for scattered physical pages. Should that be the
case virtio-gpu must call dma_memory_map() again with the remaining
range instead of simply throwing an error.
Note that this change implies the number of iov entries may differ from
the number of mapping entries sent by the guest. Therefore the iov_len
bookkeeping needs some updates too, we have to explicitly pass around
the iov length now.
