Motivation for this change

• efl: propagate utillinux, fribidi and SDL2, which are runtime dependencies

• ephoto: 1.0 -> 1.5

• efl: remove old version 1.19.1

• terminology: 1.0.0 -> 1.1.0

• efl applications: use vanilla pkg-config

  Use vanilla pkg-config to build EFL applications.

  The EFL library has a set of pkg-config files (*.pc) which uses private requirements. The default pkg-config setup on nixpkgs is patched to disable resolving those requirements. See http://bugs.freedesktop.org/show_bug.cgi?id=4738 for reference.

  As a consequence each package depending on efl has to explicitly set the search path in order to be able to find the corresponding header files.

  By using vanilla pkg-config this is not necessary (and this is the expected behaviour for pkg-config), allowing simpler nix expressions.
