However, the documentation on embedding is a bit fuzzy and all over

keeps changing and is mixed up in the docs.
This is because there is little or no embedding community. The Mozilla
community is mainly focused on Firefox development, and embedding is not
a priority.
Question0: How is embedding Gecko different from embedding XULRunner?
Which of the two have I actually done above?
They are the same thing. XULRunner is the shipping "product" which
provides the Mozilla web engine, sometimes called gecko.
Question1a: My understanding is that I can build upon GtkEmbedMoz
(provides a gtk widget for the browser content pane - I think) and
TestGtkEmbed (provides the actual window in which GtkEmbedMoz is
displayed - I think) instead of working directly with the embedding
API (too much work). Is My understanding correct? If not, please
correct it.
TestGtkEmbed is example code for how you might use GtkEmbedMoz.
But in your case, I recommend that you *not* use GtkEmbedMoz except as
perhaps a template for embedding, and instead use the embedding API more
directly.
Question1b: TestGtkEmbed was compiled as part of XULRunner SDK
compilation. If I am to build upon it, I would obviously have to
compile it as part of my app. However, a lot of stuff goes in
TestGtkEmbed, and I cannot find a good makefile or at least guidance
as to what flags, libs, and include paths to use. Any advice greatly
appreciated.

Question2: The ultimate goal would be using the mozilla engine in
headless mode - therefore I would eventually not need any of the gtk
stuff for display. In this case, am I doing an overkill by going
through GtkEmbedMoz? Would it be eventually simpler to use the
embedding API directly. Please comment.
The GtkEmbedMoz code will probably be removed in a future release of
Mozilla because it is buggy and unmaintained, and not the direction we
want for embedding in general. I would recommend using the low-level API
if possible. Also, you might want be aware of the gecko headless
rendering branch, which is rather old now but might be useful to you:
