Add GdkRGBA struct to supersede GdkColor GdkRGBA is a boxed struct similar to GdkColor, with the difference that it stores alpha information as well, and colors are stored in [0..1] doubles, in the cairo spirit. gdk_cairo_set_source_rgba() has been also added to allow easier handling of this new type.

Convert headers to #pragma once The conversion was done by guard2one.

#pragma once
Move single-include guards inside include guards gcc has optimizations for include guards that only work if they are outermost in the the header. https://bugzilla.gnome.org/show_bug.cgi?id=689810

Use a single compilation symbol We use a compilation symbol in our build to allow the inclusion of specific headers while building GTK, to avoid the need to include only the global header. Each namespace has its own compilation symbol because we used to have different libraries, and strict symbol visibility between libraries; now that we have a single library, and we can use private symbols across namespaces while building GTK, we should have a single compilation symbol, and simplify the build rules.

API: gdk: Add gdk_rgba_is_clear() and gdk_rgba_is_opaque() I want to use these inside GSK, and I'm not a fan of putting GdkRGBA APIs into it or duplicating it into GTK. So public API it is.
