ioctl: implement INOTIFY_IOC_SETNEXTWD decoding
* inotify_ioctl.c: New file. * Makefile.am (strace_SOURCES): Add it. * defs.h (DECL_IOCTL(inotify)): New declaration. * ioctl.c (ioctl_decode) <case 'I'>: Call inotify_ioctl. * tests/ioctl_inotify.c: New file. * tests/.gitignore: Add ioctl_inotify. * tests/pure_executables.list: Likewise. * tests/gen_tests.in (ioctl_inotify): New test.
