Rename native-only terminal related functions.

Looking at target_terminal_inferior etc. in async mode, I realized
that the naming of the terminal_inferior, terminal_ours,
etc. functions doesn't really give a clue that they're meant for the
native target only.  This patch renames them.  There's already
child_terminal_info using the child_ prefix, and, they're most
prominently installed by inf-child.c, so I went with the child_
prefix.  I dropped "inferior" from a couple to make the name match the
corresponding target method.

Tested on x86_64 Fedora 17, and cross built for mingw.  I didn't test
gnu-nat.c, but I think the change is as obvious as it gets.  I grepped
the tree looking for other potential spots that would need adjustment
but this is all I found.  If something breaks, it should be trivial to
fix.
