My recipe builds and ships an executable in /foo/bin/fooapp

WARNING: QA Issue: foo: Files/directories were installed but not shipped
  /foo/bin/.debug
  /foo/bin/.debug/fooapp

This file doesn't appear in the image, but is in the package folder:
./package/foo/bin/.debug/fooapp

It appears something is automatically creating these .debug files during the packaging steps, but the corresponding file isn't under packages-split.

Can someone point me to a place to learn more about how these are created and packaged?

this is done in meta/classes/package.bbclass. at the beginning of that file, you will find an overall description of what the 'packaging' steps are, and you can see, among many things:

# d) split_and_strip_files - split the files into runtime and debug and strip them.
#    Debug files include debug info split, and associated sources that end up in -dbg packages
you can then check the source code for the function split_and_strip_files.

Now, about 'packaging' the files, you need to look at meta/conf/bitbake.conf and search for FILES_{PN}-dbg. this is the default variable that specifies which files go into the -dbg package. Your issue above is because the 'default' path for binary is /usr/bin, hence the 'default' path for debug variants is /usr/bin/.debug. But if you need '/foo' , you can change these default in your recipe, by modifying FILES_{PN}xxx in your .bb file.
