Marc-André Lureau 1e21feb628 ivshmem-server: fix hugetlbfs support
As pointed out on the ML by Andrew Jones, glibc no longer permits
creating POSIX shm on hugetlbfs directly. When given a hugetlbfs path,
create a shareable file there.

Marc-André Lureau 022cffe313 ivshmem-server: use a uint16 for client ID
In practice, the number of VM is limited to MAXUINT16 in ivshmem, so use
the same limit on the server (removes a theorical infinite loop)

David Marchand a75eb03b9f contrib: add ivshmem client and server
When using ivshmem devices, notifications between guests can be sent as
interrupts using a ivshmem-server (typical use described in documentation).
The client is provided as a debug tool.
