osdep: protect qemu/osdep.h with extern "C"
System headers may include templates if compiled with a C++ compiler,
which cause the compiler to complain if qemu/osdep.h is included
within a C++ source file's 'extern "C"' block. Add
an 'extern "C"' block directly to qemu/osdep.h, so that
system headers can be kept out of it.
There is a stray declaration early in qemu/osdep.h, which needs
to be special cased. Add a definition in qemu/compiler.h to
make it look nice.
config-host.h, CONFIG_TARGET, exec/poison.h and qemu/compiler.h
are included outside the 'extern "C"' block; that is not
an issue because they consist entirely of preprocessor directives.
This allows us to move the include of osdep.h in our two C++
source files outside the extern "C" block they were previously
using for it, which in turn means that they compile successfully
against newer versions of glib which insist that glib.h is
*not* inside an extern "C" block.
