rng-builtin: add an RNG backend that uses qemu_guest_getrandom() Add a new RNG backend using QEMU builtin getrandom function. It can be created and used with something like: ... -object rng-builtin,id=rng0 -device virtio-rng,rng=rng0 ...

add memdev backend infrastructure Provides framework for splitting host RAM allocation/ policies into a separate backend that could be used by devices. Initially only legacy RAM backend is provided, which uses memory_region_init_ram() allocator and compatible with every CLI option that affects memory_region_init_ram().

hostmem-file: make available memory-backend-file on POSIX-based hosts Before this change, memory-backend-file object is valid for Linux hosts only because hostmem-file.c is compiled only on Linux hosts. However, other POSIX-based hosts (such as macOS) can support memory-backend-file object in the same way as on Linux hosts. This patch makes hostmem-file.c and related functions to be compiled on all POSIX-based hosts to make available memory-backend-file on them.

Add memfd based hostmem Add a new memory backend, similar to hostmem-file, except that it doesn't need to create files. It also enforces memory sealing. This backend is mainly useful for sharing the memory with other processes. Note that Linux supports transparent huge-pages of shmem/memfd memory since 4.8. It is relatively easier to set up THP than a dedicate hugepage mount point by using "madvise" in /sys/kernel/mm/transparent_hugepage/shmem_enabled. Since 4.14, memfd allows to set hugetlb requirement explicitly. Pending for merge in 4.16 is memfd sealing support for hugetlb backed memory.

Add vhost-user-backend Create a vhost-user-backend object that holds a connection to a vhost-user backend (or "slave" process) and can be referenced from virtio devices that support it. See later patches for input & gpu usage. Note: a previous iteration of this object made it user-creatable, and allowed managed sub-process spawning, but that has been dropped for now.
