1d649244b3 ivshmem: Rename property memdev to x-memdev for 2.5
The device's guest interface and its QEMU user interface are
flawed^Whotly debated.  We'll resolve that in the next development
cycle, probably by deprecating the device in favour of a cleaned up,
but not quite compatible revision.

To avoid adding more baggage to the soon-to-be-deprecated interface,
mark property "memdev" as experimental, by renaming it to "x-memdev".
It's the only recent user interface change.

1613094766 tests/ivshmem-test: Supply missing initializer in get_device()
If the device isn't found, the assertion uses dev without
initialization.  Fix that.

2048a2a491 tests: classify some ivshmem tests as slow
Some tests may take long to run, move them under g_test_slow()
condition.

The 5s timeout for the "server" test will have to be adjusted to the worst
known time (for the records, it takes ~0.2s on my host). The "pair"
test takes ~1.7, a quickest version could be implemented.

d9453c93fe ivshmem: add hostmem backend
Instead of handling allocation, teach ivshmem to use a memory backend.
This allows to use hugetlbfs backed memory now.

ddef6a0d68 tests: add ivshmem qtest
Adds 4 ivshmemtests:
- single qemu instance and basic IO
- pair of instances, check memory sharing
- pair of instances with server, and MSIX
- hot plug/unplug

A temporary shm is created as well as a directory to place server
socket, both should be clear on exit and abort.

bbfc2efefe tests: Add ivshmem qtest
Note that it launches two instances, as sharing memory is the purpose of
ivshmem.
