Re-introduce the `freetype2' subdirectory for all FreeType header

Fix Savannah bug #45097.
We no longer `pollute' the namespace of possible header file names;
instead we move `ft2build.h' up by one level so that it gets
installed in the default include directory (e.g.,
/usr/local/include). After this commit, only `ft2build.h' stays in
the compiler's include path.
No visible changes for the user who follows the standard FreeType
header inclusion rules.
* include/*: Move to ...

Make Jam support work again.
This is just very basic stuff and just a little bit tested on

[base] Don't allocate `library->raster_pool' anymore.
It's unused after the following commits:
[raster] Allocate render pool for mono rasterizer on the stack.
[raster] Remove 5-level gray AA mode from monochrome rasterizer.
The value of FT_RENDER_POOL_SIZE still serves the purpose it used to
serve, which is, to adjust the pool size. But the pool is now
allocated on the stack on demand.
* src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement.

[base] Do not reorder library->renderers upon use.
Instead of keeping `library->renderers' in a MRU order, just leave
it as-is. The MRU machinery wasn't thread-safe.
With this patch, rasterizing glyphs from different faces from
different threads doesn't fail choosing rasterizer
(FT_Err_Cannot_Render_Glyph).
Easiest to see that crash was to add a `printf' (or otherwise let
thread yield in FT_Throw with debugging enabled).
* src/base/ftobjs.c (FT_Render_Glyph_Internal), src/base/ftoutln.c
(FT_Outline_Render): Don't call `FT_Set_Renderer'.

Fix Savannah bug #43976.
Assure that FreeType's internal include directories are found before
`CPPFLAGS' (which might be set by the user in the environment), and
`CPPFLAGS' before `CFLAGS'.

files handled in `freetype.mk'.
(.c.$O): Removed, unused.

bits with long division. This optimization is especially noticeable
for smaller dividends that barely use the high register.
* src/base/ftcalc.c (ft_div64by32): Updated.
