When a signal change a state of a edje box to a state that was already active
and we add/del a item of edje box a crash happen.
Example:
test.edc:
collections {
group {
name: "box_text";
parts {
part {
name: "elm.box.buttons";
type: BOX;
description {
state: "default" 0.0;
min: 0 100;
max: 9999 100;
align: 0 0;
box {
layout: "horizontal";
min: 1 1;
}
visible: 0;
}
description {
state: "show" 0.0;
inherit: "default" 0.0;
visible: 1;
}
}
}
programs {
program {
signal: "show,buttons";
source: "gui";
action: STATE_SET "show" 0.0;
transition: ACCELERATE 1;
target: "elm.box.buttons";
}
program {
signal: "hide,buttons";
source: "gui";
action: STATE_SET "default" 0.0;
transition: ACCELERATE 1;
target: "elm.box.buttons";
}
}
}
}
test.c:
//Compile with:
//gcc -g test.c -o test `pkg-config --cflags --libs elementary edje ecore`

We called anim->start aftwards just to be sure to stick to something if
all fail.
this is still in progress, mostly the multisense stuff is pending.
it seems that when we merge ecore_audio in edje the libremix and
similar are gone, at least from Edje, and will be in ecore_audio
itself (or pulseaudio).
Changes:
* __UNUSED__ to EINA_UNUSED
* binaries (epp, embryo_cc, edje_cc) now consider EFL_RUN_IN_TREE and
will assume the binaries are still not installed, running from
build tree location (needs more testing, maybe doesn't work with
srcdir != builddir, still doesn't solve cross compile builds)
