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().

The linux-user syscall emulation layer currently supports the
openat family of syscalls via two mechanisms: simply calling
the corresponding libc functions, and making direct syscalls.
Since glibc has supported these functions since at least glibc
2.5, there's no real need to retain the (essentially untested)
direct syscall fallback code, so simply delete it. This allows
us to remove some ifdeffery that was attempting to disable
provision of some of the syscalls if the host didn't seem to
support them, which in some cases was actually wrong (eg where
there are several flavours of the syscall and we only need
one of them, not necessarily the exact one the guest has,
as with the fstatat* calls).

The header slirp/slirp.h is an internal header for slirp, and
main-loop.c does not use internals from there.  Instead, it uses
public functions (slirp_update_timeout(), slirp_pollfds_fill()
etc) which are declared in slirp/libslirp.h.

Including slirp/slirp.h is somewhat dangerous since it redefines
errno on WIN32, so any file including it may misbehave wrt errno.

Unfortunately libslirp isn't self-contained, it needs declaration
of struct in_addr, which is provided by qemu/sockets.h.  Maybe
instead of #including qemu/sockets.h before libslirp.h, it is
better to make the latter self-contained.

The common KVM code insists on calling kvm_arch_init_irq_routing()

Unlike x86, PPC does not have one default irqchip, so there's no common
code that we'd stick here.  Even if you ignore the routes themselves,
which even on x86 are not set up in this function, the initial XICS
kernel implementation will not support IRQ routing, so it's best to
leave even the general feature flags up to the specific irqchip code.

Certain options (-no-frame, -alt-grab, -ctrl-grab) only make sense with SDL.
When compiling without SDL, these options (and -no-quit) print an error message
and exit qemu.

In case QEMU is compiled with SDL support, the three aforementioned options
still do not make sense with other display types. This patch addresses that
issue by printing a warning. I have chosen not to exit QEMU afterwards because
having the option is not harmful and before this patch it would be ignored
anyway.

By delaying the sanity check from compile-time with some ifdefs to run-time,
-no-quit is now also properly supported when compiling without SDL.
