[pgpool-committers: 630] pgpool: Fix inifinit loop in SSL mode. When there's pending data in SSL

[Tatsuo Ishii]

Fix inifinit loop in SSL mode. When there's pending data in SSL layer
of frontend, pool_process_query() checks pending data in backend.  If
there's non, it loops again and checks frontend/backend receive buffer
by using is_cache_empty(). Unfortunately it first checks pending data
in SSL layer of frontend, thus goes to backend data and checks
again(infinite loop).  The solution is, if there's pending data in SSL
layer of frontend and query is not in progress, call
ProcessFrontendResponse() to process new request from frontend.
