This is for now just a small experiment. It was based on the experiment made
with OpenMP. I prefered to only use Eina here as we have already all the infrastructure
to do this nicely and simply. As a result I get a 65% speed improved on average for
the involved scaling operation. The secondary CPU is on my laptop running with a load of
75% percent. I don't have right now the time to do power consumption analysis, but I
think it shouldn't be to bad. I am also not throwing more core at this as we are not able
to use the second core at its max already, so additional core may result in a bigger
energy loss without enough gain.
A rare case of garbage data would happen if smooth scaling
was called with a mask and 1:1 scaling. Use the proper
render_op to COPY for the first pass.

This commit introduces changes to the low-level draw functions
of the SW engine considering the existence of an alpha mask image.
Features:
- Font masking (TEXT, TEXTBLOCK),
- Rectangle masking,
- Image masking (all image scaling functions should be handled).
The mask image itself is not yet set in the draw context (see
following commits).

Idea originated from Cedric the b0rker.
This is a big fat search-and-replace commit.
This commit also introduces space changes... Sorry for the mix.
NOTE: This commit may have one side effect as there was some very
dubious code chaning the dst image's alpha flag in the
Gfx get functions. Logically this didn't make sense (at
draw time the dst alpha should already be well defined),
so it should be safe.
Evas_Common.h should be used for the public header, and rather rename
evas_common.h internal header to another name.
Sa:
Evas_Common_Header.h -> Evas_Common.h
evas_common.h -> evas_common_private.h
Shouldn't have both Evas_Common.h and evas_common.h because of case
insensitive filesystems.
This patch should make us get a reference on images, maps and glyphs
which are sent in a command to the render thread. Before we were doing
some useless ref and unref operations.

This patch refactors common code for image draws - so that it can be used
by other engines and *threaded* X11.

I've tested make -j 3 install and it works nicely
I've tested expedite with software and opengl xlib,
and it works. Not tested other engines, so please
report any problems (engines or other) on the ML.
TODO: examples and tests, I'll add them later
ISSUE: Eina_Unicode size check. It indirectly depends on
eina_config.h, which is created at the end of the
configure script. So its size is always 0. I don't
know how that size is used, so I can't do a lot,
for now.
