When SO_OOBINLINE is enabled on a socket, MSG_OOB can be recv()ed
without MSG_OOB flag, and ioctl(SIOCATMARK) will behaves differently.
This patch adds some test cases for SO_OOBINLINE.
Note the new test cases found two bugs in TCP.
1) After reading OOB data with non-inline mode, we can re-read
the data by setting SO_OOBINLINE.
# RUN msg_oob.no_peek.inline_oob_ahead_break ...
# msg_oob.c:146:inline_oob_ahead_break:AF_UNIX :world
# msg_oob.c:147:inline_oob_ahead_break:TCP :oworld
# OK msg_oob.no_peek.inline_oob_ahead_break
ok 14 msg_oob.no_peek.inline_oob_ahead_break
2) The head OOB data is dropped if SO_OOBINLINE is disabled
if a new OOB data is queued.
# RUN msg_oob.no_peek.inline_ex_oob_drop ...
# msg_oob.c:171:inline_ex_oob_drop:AF_UNIX :x
# msg_oob.c:172:inline_ex_oob_drop:TCP :y
# msg_oob.c:146:inline_ex_oob_drop:AF_UNIX :y
# msg_oob.c:147:inline_ex_oob_drop:TCP :Resource temporarily unavailable
# OK msg_oob.no_peek.inline_ex_oob_drop
ok 17 msg_oob.no_peek.inline_ex_oob_drop
