add -fret-clean option (amd64 and i386 only at first), defaulting to off. This causes the caller to cleans the return address off the stack after a callq completes. The option is best used in low-level libraries (such as libc), because libc contains low-level system call stubs. The option reduces hints (found on the stale parts of the stack) about libc.so's mapping location, and together with random-relinking, relro got/pic, and xonly makes some exploit methods more difficult. ok mortimer, mlarkin, much discussion with kettenis, in snaps for 2 weeks.
