SubjectRe: [PATCH glibc] Linux: Include <linux/sockios.h> in <bits/socket.h> under __USE_MISC

<sys/ioctl.h> can be confusing because some of the constants may depend
on types that aren't declared by including the header. This makes their
macros unusable. Defining ioctl constants in headers which also provide
the matching types avoids that problem at least, also it can introduce
namespace issues.
