api: configurable binary api client rx pthread fcn
Add vl_client_connect_to_vlib_thread_fn (...) and export the memory_client_main_t definition. If you use this new API, make sure not to miss the setjmp / longjmp dance shown in .../src/vlibmemory/memory_client.c:rx_thread_fn(...), which is required for the rx pthread to terminate cleanly; please process client delete reply messages in the rx thread... Type: refactor Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: Ia67038ec59e2e14b174c67afca15b2c3f67a4d20
