Add a configurable state dump facility for debugging EFA RDM hangs. When FI_EFA_STATE_DUMP_SIGNAL is set to a signal number (e.g. 12 for SIGUSR2), the provider installs a handler that dumps EP counters and per-peer state (outstanding TXE/RXE, reorder buffer, RNR backoff, overflow) to stderr on the next CQ progress call. In debug builds, queued packet headers are additionally printed via efa_rdm_pke_print(). Signed-off-by: Shi Jin <sjina@amazon.com>
