Remove as many hard-coded constants from the MIPS vfork.S as possible.

We could do better, but not without MIPS cleaning up their kernel headers.

Fix dev_t (for LP64).

32-bit Android's dev_t was wrong too. We can't fix that without ABI breakage,
but we can at least fix 64-bit Android. And add tests.

Add TCPOPT_* constants.

Adds the TCPOPT_* constants from NetBSD. Note that the BSDs also have
TCPOPT_SIGNATURE, but Linux calls that TCPOPT_MD5SIG and glibc doesn't
have any corresponding constant yet, so let's wait until we see which name
wins out.
