Subject: [PATCH 1/1] add test cases

The following test cases are added to test more interfaces of npth:
t-condlock.c    test npth condlock interfaces
t-fork-enhance.c    test npth fork interfaces
t-rwlock.c    test npth rwlock interfaces
t-signal.c    test npth signal interfaces
t-socket.c    test npth socket interfaces
