David CARLIER c9c8b88f0b util/qemu-openpty.c: Don't assume pty.h is glibc-only
Instead of using an OS-specific ifdef test to select the "openpty()
is in pty.h" codepath, make configure check for the existence of
the header and use the new CONFIG_PTY instead.

This is necessary to build on Haiku, which also provides openpty()
via pty.h.

Thomas Huth 9df8b20d16 configure / util: Auto-detect the availability of openpty()
Recent versions of Solaris (v11.4) now feature an openpty() function,
too, causing a build failure since we ship our own implementation of
openpty() for Solaris in util/qemu-openpty.c so far. Since there are
now both variants available in the wild, with and without this function
(and illumos is said to not have this function yet), let's introduce a
proper HAVE_OPENPTY define for this to fix the build failure.

Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

Natanael Copa 6ad3f09bd4 util/qemu-openpty: fix build with musl libc by include termios.h as fallback
Include termios.h as POSIX fallback when not glibc, bsd or solaris.
POSIX says that termios.h should define struct termios and TCAFLUSH.
http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/termios.h.html

This fixes the following compile errors with musl libc:

util/qemu-openpty.c: In function 'qemu_openpty_raw':
util/qemu-openpty.c:112:20: error: storage size of 'tty' isn't known
     struct termios tty;
                    ^
...
util/qemu-openpty.c:128:24: error: 'TCSAFLUSH' undeclared (first use in this function)
     tcsetattr(*aslave, TCSAFLUSH, &tty);
                        ^

Michael Tokarev 4efeabbbe8 create qemu_openpty_raw() helper function and move it to a separate file
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.

This version has been verified to build correctly on Linux,
OpenBSD, FreeBSD and OpenIndiana.  On the latter it lets qemu
to be built with gtk gui which were not possible there due to
missing openpty() and cfmakeraw().
