[Libguestfs] [PATCH 1/3] generator: c: move internal functions

Move the generate_all_structs and generate_all_headers functions,
previously internal within the implementation of generate_guestfs_h, to
be usable by other functions in the same "C" module (but not public).

Only code motion.

[Libguestfs] [PATCH 2/3] Split internal stuff out of guestfs.h

Create a new guestfs-private.h header, and move there the definitions of
all the actions with visibility VInternal, and all the private structs:
they are not meant to be used, not even seen, outside of the library.

Include the new header where needed, which means also a couple of places
outside the library (but they are tests, so it is acceptable for now).

The result of this is mostly motion of function and structs
declarations.

[Libguestfs] [PATCH 3/3] generator: do not output GUESTFS_HAVE_* defines for internal stuff

Output the GUESTFS_HAVE_* defines only for actions with visibility
different than VInternal, and for structs not marked as internal.
The reason is that all the above are usable only by the library itself
(and at most by tests), and users of the library now cannot even get the
function declarations.

OK I understand why this change is made, but the naming of the new
header is super-confusing.  We already have guestfs-internal.h and
guestfs-internal-actions.h (containing guestfs_impl_*), and now we're
adding guestfs-private.h containing guestfs_internal_* functions.

Hmm.

So the idea is fine, but renaming things to make them more sensible.

How about guestfs-internal-impl.h for guestfs_impl_*
and guestfs-internal-apis.h for guestfs_internal_* ?

Rich.
