Rather than rolling custom concatenate-strings macros for the
QEMU_BUILD_BUG_ON macro to use, use the glue() macro we already
have (since it's now available to us in this header).

osdep.h has a few things which are really compiler specific;
move them to compiler.h, and include compiler.h from osdep.h.

It is reasonably common to want to create an object, set a
number of properties, register it in the hierarchy and then
mark it as complete (if a user creatable type). This requires
quite a lot of error prone, verbose, boilerplate code to achieve.
First a pair of functions object_set_props() / object_set_propv()
are added which allow for a list of objects to be set in
one single API call.
Then object_new_with_props() / object_new_with_propv() constructors
are added which simplify the sequence of calls to create an
object, populate properties, register in the object composition
tree and mark the object complete, into a single method call.
Usage would be:
Error *err = NULL;
Object *obj;
obj = object_new_with_propv(TYPE_MEMORY_BACKEND_FILE,
object_get_objects_root(),
"hostmem0",
&err,
"share", "yes",
"mem-path", "/dev/shm/somefile",
"prealloc", "yes",
"size", "1048576",
NULL);
Note all property values are passed in string form and will
be parsed into their required data types, using normal QOM
semantics for parsing from string format.

The combination of always_inline + artificial allows tiny inline
functions to be written that do not interfere with debugging.
In particular, gdb will not step into an artificial function.
The always_inline attribute was introduced in gcc 4.2,
and the artificial attribute was introduced in gcc 4.3.

Using macros instead of static functions for dolog and for ldebug
simplifies the code and can also reduce the total code size.
GCC_ATTR was only used in audio_int.h, so it is now unused and
the definition can be removed from compiler.h.

GCC 4.8.0 introduces a new warning:
block/qcow2-snapshot.c: In function 'qcow2_write_snapshots’:
block/qcow2-snapshot.c:252:18: error: typedef 'qemu_build_bug_on__253'
locally defined but not used [-Werror=unused-local-typedefs]
QEMU_BUILD_BUG_ON(offsetof(QCowHeader, snapshots_offset) !=
^
cc1: all warnings being treated as errors
(Caret diagnostics aren't perfect yet with macros... :)) Work around it
with __attribute__((unused)).
