ggtags is a fairly thin elisp package that interfaces to command-line
Gnu Global.

cedet also provides a thin elisp package (cedet-global) that interfaces to
command-line Gnu Global, and is integrated with the rest of cedet.

There's no reason to have both cedet-global and ggtags.

There are many reasons to keep cedet, so it makes sense to provide xref
support for Gnu Global via the cedet package, not the ggtags package.

There may be features that are in ggtags that are not in cedet; I'll
have to check after I get the basics working, and see if it is
reasonable to add them to cedet.
