it's own utility (as per raster's request/idea). Remove explicit
x_clags in Makefile.am(s) as they are no longer needed.
NB: I added some additional libs to the precache stuffs (even tho it's
not used right now). Also a newer e_main (more optimized).
NB: IF you are brave and want to test this, build evas w/ xcb, build
ecore w/ xcb, then rebuild E. Also, disable building opengl in both
evas & ecore (it's not ready for public consumption when paired w/ xcb).
