In two places qemu uses openpty() which is very system-dependent,
and in both places the pty is switched to raw mode as well.
Make a wrapper function which does both steps, and move all the
system-dependent complexity into a separate file, together
with static/local implementations of openpty() and cfmakeraw()
from qemu-char.c.
It is in a separate file, not part of oslib-posix.c, because
openpty() often resides in -lutil which is not linked to
every program qemu builds.
This change removes #including of <pty.h>, <termios.h>
and other rather specific system headers out of qemu-common.h,
which isn't a place for such specific headers really.

Changes since v1:
- added a forgotten #include <termios.h> for *BSD,
which was recently added into qemu-common.h by
Brad Smith, and which I intended to use in
qemu-openpty.c too, but somehow forgot.
And one extra comment. I especially took existing
code and used it almost unmodified, to have one
code moving change, with all other possible
improvements/cleanups to follow later.
