mesa/radeonsi is going to support explicit modifier which
may export a multi-plane texture. For example, texture with
DCC enabled (a compressed format) has two planes, one with
compressed data, the other with meta data for compression.
v2:
* change API qemu_dmabuf_get_fd/offset/stride to
qemu_dmabuf_get_fds/offsets/strides.
* change API qemu_dmabuf_dup_fd to qemu_dmabuf_dup_fds.
* add an extra arg to these API for the length of the
array.
