Log message:
Set BUILDLINK_ABI_DEPENDS correctly (with +=, not ?=)
It turns out there were a lot of these.

Log message:
Fix build with png-1.5.

Log message:
png shlib name changed for png>=1.5.0, so bump PKGREVISIONs.

Log message:
Bump PKGREVISION for libpng shlib name change.
Also add some patches to remove use of deprecated symbols and fix other
problems when looking for or compiling against libpng-1.4.x.

Log message:
The cmake utility recommends using OPENGL_gl_LIBRARY if GLU is not required.
This also fixes the build in some circumstances: if cmake finds an installed
libGLU the build will fail, because we don't buildlink it.
