Move macro QEMU_GNUC_PREREQ to compiler.h

The macro is compiler specific and does not depend on the operating system.

Move macro QEMU_GNUC_PREREQ from osdep.h to compiler.h
and use it to simplify existing code.

host-utils.h uses this macro, so it now needs compiler.h...

The code which tests whether gcc supports warn_unused_result was wrong.
Remove the wrong test from configure and replace it by code using
macro QEMU_GNUC_PREREQ in compiler.h.

Add new macro QEMU_PACKED for packed C structures

A packed struct needs different gcc attributes for compilations
with MinGW compilers because glib-2.0 adds compiler flag
-mms-bitfields which modifies the packing algorithm.

Attribute gcc_struct reverses the negative effects of -mms-bitfields....

Introduce compiler.h header file

This moves compiler related macros from qemu-common.h to compiler.h.

The reason for this change is that there are simple header files that
depend only on the compiler macros, so including qemu-common.h is overkill.

Besides, qemu-common.h is bloated and will benefit from some splitting....
