Add --multi-clients to enable experimental multi-client support.
Note that multi-client should be enabled only when the clients know
and trust each other. This is because resources are global among
the clients. Two clients trying to create two resources with the
same id will result in an id conflict for example.
Proper multi-client support requires changes to the protocol. The
main change will be for the server to generate globally unique
resource ids and enforce access controls.

Add vtest_server_run to replace vtest_server_run_renderer. The new
function is the main loop of the server, which
- accepts new client connections
- dispatches client commands
- removes inactive clients
- lazily initi/cleanup the renderer
- optionally forks for each connection
in a single loop.

This commit moves input/out_fd into vtest_context to allow multiple
clients, where each client is represented by a vtest_context and has
its own vtest_input.
Note that clients must know and trust each other, especially when it
comes to resources. There is no conflict or ownership check in
vtest_create_resource or vtest_resource_unref respectively yet.
There is also no resource sharing support yet.

With the main aim of making vtest's usage of virglrenderer more similar
to that of QEMU, this patch sets a backing store to each resource and
reads from or writes to at each transfer operation.
v2: - Instead of adding a callback on resource destruction, free the
iovec when we unref a resource as we know that we won't be doing
anything else with it. (Dave Airlie)
v3: - Store pointers to iovecs in the global to also release them
v4: - Add new commands for resource creation and transfers, to be used
when protocol version >= 1.
v5: - Replaced the global array of iovecs with a hash table because some
es31 tests create thousands of resources and reach any sane limit.
