Revert "Linux: Keep termios ioctl constants strictly internal"

Browse Source 
This reverts commit 3d3572f590.

Reason for revert: TCGETS etc. work to some extent on at least
a subset of architectures, so there is no pressing need to force
applications off them.  Removal of the macros breaks building
the sanitizers, impacting both GCC and LLVM.
