We're going to stub certain modules and functions for Windows builds. Some of them will be implemented in subsequent commits, some are platform specific and will be skipped. Modules: * module.c * subprocess.cc * blkdev.cc * dns_resolve.cc * numa.cc * syslog.h * statvfs.h * libblk * neorados Functions: x signal functions x fork x chown * socketpair_cloexec * dump_open_fds * run_cmd * is_symlink * CInode::d_type * nbd commands Signed-off-by: Lucian Petrut <lpetrut@cloudbasesolutions.com> Signed-off-by: Alin Gabriel Serdean <aserdean@cloudbasesolutions.com>
