vppinfra: Expose function setting __os_thread_index
Type: feature
This is needed when creating pthreads in client applications,
they need a way to set __os_thread_index per thread
that does not conflict with the binary API thread index.
If __os_thread_index is left to 0 in two client pthreads and
they call vl_msg_api_alloc and vec_resize at the same time
it can fail due to them sharing (and push/poping) the same
clib_per_cpu_mheaps slot.
