ibv_td(thread domain)

[minxinhao]

Ibv_td seems to do the same job as smart, which was integrated in rdma-core in 2017.

ibv_alloc_td() cannot meet our needs. Although it allows users to allocate resources in a per-threaded manner, he/she also needs to call ibv_alloc_parent_domain() to get ibv_pd objects for each thread. This still makes duplicated memory regions / memory windows like per-context policy mentioned in this paper.
