906709a151 libqemustub: sysbus_get_default() stub
The stub will be used on cases where sysbus.c is not compiled in (e.g.
*-user).

Note that code that uses NULL as the bus with qdev{_try,}_create()
implicitly uses sysbus_get_default() as the bus, and will still require
sysbus.c to be compiled in.

083a5f8731 libqemustub: vmstate register/unregister stubs
Add vmstate stub functions, so that qdev.o can be used without savevm.o
when vmstate support is not necessary (i.e. by *-user).

41c6bcd912 libqemustub: Add qemu_[un]register_reset() stubs
This will be useful for code that don't call qemu_devices_reset() (e.g.
*-user). If qemu_devices_reset() is never called, it means we don't need
to keep track of the reset handler list.

3bc2f570ec build: replace weak symbols with a static library
Weak symbols were a nice idea, but they turned out not to be a good one.
Toolchain support is just too sparse, in particular llvm-gcc is totally
broken.

This patch uses a surprisingly low-tech approach: a static library.
Symbols in a static library are always overridden by symbols in an
object file.  Furthermore, if you place each function in a separate
source file, object files for unused functions will not be taken in.
This means that each function can use all the dependencies that it needs
(especially QAPI stuff such as error_setg).

Thus, all stubs are placed in separate object files and put together in
a static library.  The library then is linked to all programs.
