This series add test case for fd passing with unix socket at runtime. Since getfd and closefd interface will interact with monitor's data, so it will help to do regression test for monitor patches. Since python2 do not support sendmsg(), so a C helper program is added to do the job.
v2: 1: add missing $ in the makefile rule. v3: Address Eric's comments: 1: typo fix, remove "." in the end of error message, strick check argc as "!=", use EXIT_SUCCESS and EXIT_FAILURE as exit values, strict error check for strtol() call. Address Luiz's comments: 1: change the helper program parameter as "bin < socket-fd > < file-path >", the program open the file itself now, data parameter is removed and blank is always used as iov data, better usage tip message, folder the string parsing code into a function. 2: related change for helper program parameter change. 3: related change for helper program parameter change. Other: 1: remove "LINK" rule in makefile, remove fd checking code inside send_fd() since it is already checked before calling, add '' around %s for path and number string in error message. 2: renamed fd_bin to bin in send_fd_scm() to tip better, add '' around %s for path in error message.
