Port the hipObject v2 reliable-connection session core into cuwrapper/rc: the session table and state machine, the wire codec for the hipobj-rc-v2 headers, request parsing, the injectable clock and randomness sources, the transport layer (QP/CQ lifecycle, RTR/RTS transitions, staging registration), the data phase (RDMA write with immediate for GET, receive with immediate for PUT), the RDMA token codec, and the dynamically loaded ibverbs shim (ibv-core.h plus the dlopen host binding). The sources are a port of the upstream hipObject v2 core, kept close to the original so the two trees can be diffed during review. Nothing links against them yet; a Makefile rule builds the objects into rdma/librcserver.a for the ABI layer that follows. Signed-off-by: Jihyeon Gim <potatogim@potatogim.net>
