glibc does not update the tcp_info struct because they consider
changing the size an abi break, but then users have to include
linux uapi headers for the new apis which can conflict with
libc headers. i added the new members but i don't know which
approach is better.

some sysvipc padding fields got renamed on 32bit time_t targets,
see e.g. linux commit c039dbd5f4bbf3547fde7ce9f7403e25938aa253
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c039dbd5f4bbf3547fde7ce9f7403e25938aa253
i haven't made appropriate changes in musl yet and wonder
if this is something we want to expose.

in the signalfd patch i changed a pad struct member to __pad.

i don't now of other issues.
