This patch fixes the problem with bitfield of signed types (ie: char),
where the bit would be used for the signal, so 1 is considered -0 and
thus 0.
Move all the single bit fields to Evas_Bool, making it clear and also
avoiding these problems since Evas_Bool is unsigned char.

2. free then malloc otherwise realloc might ALSO have to memcpy if it cant
resize the segment whihc means overhead we dont need/want.

By having a layer as a short (16 bits) we can pack it together with
the bitfields, saving 4 bytes per sub-struct, 8 bytes in total, also
bringing the struct down from 4 to 3 cachelines on my laptop.
Rationale: layers are mostly used to differentiate groups of objects
and they stacking, usually we have few layers and we use very large or
very small numbers to make a layer be at the top or at the bottom, but
usually we don't need so many layers.
Caution: code that use values like 999999 will break, so fix your
code! I'll provide another patch to fix all the CVS using these large
values.

This saves 20 bytes, bringing Evas_Object to 200 bytes, by moving data
specific to smart objects to their own struct (Evas_Object_Smart).
There is still one remaining member that could be removed:
smart.smart, this is used mainly to identify if one object is a smart
object or not. One possibility would be to add a bitfield to state
that, but another possibility is to check Evas_Object::object_data
and see if it's a smart or not.

Interpolation color_space (now ASHV or ARGB) was being used inside a
struct with 4 byte alignment. Remove it from the struct and make it a
bitfield so can be packed with the other fields. This saves 2
integers, so 8 bytes.

This is a repack of bitfield members, was tested on GNU/Linux + GCC 4.1.2
and works fine. Needs further testing on other compilers.

Size hints are useful, but wasting 36 bytes for it on every object is a bit
too much: clippers and lots of other objects will have no need for it.
Now it's a pointer to a struct that will be allocated just when some value
is set, wasting 4/8 bytes more for the pointer when it is used, but saving
32/28 bytes when it is not.
This will also help to have alignment properties in future, that can come
as hints, without too much impact on memory consumption.

This will help the use of Evas_Bool to define bitfield structs like in:
struct s {
Evas_Bool a:1;
Evas_Bool b:1;
Evas_Bool c:1;
Evas_Bool d:1;
Evas_Bool e:1;
Evas_Bool f:1;
Evas_Bool g:1;
Evas_Bool h:1;
Evas_Bool i:1;
};
It must be unsigned or it would use the signal bit, having "a == 0" to
be true anyway, as it would be just +0 and -0.

The engine is not entirely working right now. Recent devices which
supports the raw frame buffer should work though. But having it in
cvs will help me as I'm coding it most of the time "blindly" (no
device to test it)
* minor formatting in the top evel Makefile.am too
SVN revision: 34354
* formatting
* put WIN32_CFLAGS in AM_CFLAGS and not AM_CPPFLAGS, as it is where it belongs
* rename create_shared_lib to lt_no_undefined
* pass -Wl,--enable-auto-import to libtool when compiling with cegcc
* add files to EXTRA_DIST only when they are not in _SOURCES or _include_HEADERS (they
are added anyway)
