them when reading in background mode.
Primary goal of this commit is to fix an annoying issue - when processing and saving .blend
files in background mode you lose their thumbnails, since it can only be generated with
an OpenGL context.
Solution to that is to read .blend thumbnail while reading .blend file (only done in background
mode currently), and store it in Main struct.
Also, this lead to removing .blend file reading code from thumb_blend (no need to have doublons).
We now have a small interface in regular reading code area, which keeps it reasonbaly light
by only reading/parsing header info, and first few BHead blocks.
This makes code reading .blend thumbnail about 3 to 4 times slower than previous highly specialized
one in blend_thumb.c, but overall thumbnail generation of a big .blend files folder only grows
of about 1%, think we can bare with it.
Finally, since thumbnail is now optionally stored in Main struct, it makes it easy to allow user
to define their own custom one (instead of auto-generated one). RNA API for this was not added though,
accessing that kind of .blend meta-data has to be rethought a bit on a bigger level first.

added some missing functions too - which are not used yep but should be there for api completeness.
* CDDM_set_mloop
* CDDM_set_mpoly
* BLI_mempool_count

without the underscores these clogged up the namespace for autocompleation which was annoying.

- rename 'name', 'dir' --> 'filepath' where these actually represent a file path to avoid confusion.
- bugfix for possible (but unlikely) uninitialized string.
- remove commented script append function, now we have a python api for this.

more sensible in the output.

mostly replace strcpy with BLI_strncpy and multiple strcat's with a BLI_snprintf().
also fix possible crash if CWD isnt available.

- made interface, windowmanager, readfile build without unused warnings.
- re-arranged CMake's source/blender build order so less changed libs are build later, eg: IK, avi

- uses same thumbnail system as image browser
- blend files show thumbnails in ubuntu/gnome (freedesktop spec)
- 128x128 images are embedded into the blend file header, a simple loader avoids reading the entire blend file to extract it when generating thumbnails in the file selector.
When the image browser reads a directory it loads images and creates thumbnails, blend files embedded images are treated just like loading an image.
- the thumbnail is created from the camera view in solid mode. (no camera == no thumbnal).
- readfile/writefile.c: had to use the 'TEST' code name to save thumbnails, anything else would segfault older blender versions on load. (its not used elsewhere).

- removed context usage, should not be in this module
- remove G.main usage, now is passed along
- still some globals in use here, goal is to get rid of those too,
so that it's possible to load/save blendfiles without having to
think about some global state.

Makefiles especially, and of course the windowmanager DNA!

- file-to-memory save
- incremental difference steps (compression)
everthing has been tightly coded to use minimum of memcpy or allocs. In
fact this system works with a single full buffer (=file) in memory, and undosteps as differences from it.
Speed gain is factor 4-8 faster. I've added it in CTRL+ALT+T timer menu for
a test. Please note the gain is especially in the undo-storing, not in
retrieving undo.
Also new: file read option to skip UI read (file menu). This now also is
default for the undo system.

So we should be all set now :)

(adding)
#ifdef HAVE_CONFIG_H
#include <config.h>
#endif
also the Makefile.in's were from previous patch adding
the system depend stuff to configure.ac
