Neil Roberts ca5197a70c error: Don't allocate a new CoglError when propagating
The _cogl_propagate_error() function takes ownership of the incoming
error pointer so there's no need to allocate a new error when passing
it on. The errors can potentially be passed up from a number of layers
so it seems worthwhile to avoid the allocation.

The _cogl_propagate_gerror() function was previously using
_cogl_propagate_error(). Presumably this would not have worked because
that function would try to free the error from glib using
cogl_error_free but that would use the wrong free function and thus
the wrong slice allocator. The GError propagating function is only
used when gdk-pixbuf is enabled which now requires glib support anyway
so we can just avoid defining the function when compiling without
glib.
