Justine Tunney 5b60e5a37d Fix termios struct on Linux
The termios::c_cc field turned out to be incorrectly defined on Linux
due to some confusion between the glibc and kernel definitions. We'll
be using the kernel definition, since it has the strongest consensus.

Fields have been have been added to struct stat for BSD compatibility
such as st_birthtim, plus the GLIBC compatibility of isystem/sys/stat
has been improved.
