Arseniy Krasnov Sept. 22, 2023, 5:24 a.m. UTC 
This adds set of tests which use io_uring for rx/tx. This test suite is
implemented as separated util like 'vsock_test' and has the same set of
input arguments as 'vsock_test'. These tests only cover cases of data
transmission (no connect/bind/accept etc).

 Changelog:
 v5(big patchset) -> v1:
  * Use LDLIBS instead of LDFLAGS.

This will fails if for example we call make with more targets,
e.g. `make vsock_test vsock_uring_test`.

I'd suggest to use something like this:

Shoud we add this new test to the "test" target as well?

Ok, but in this case, this target will always depend on liburing.

I think it's fine.

If they want to run all the tests, they need liburing. If they don't
want to build io_uring tests, they can just do `make vsock_test`.
