Richard W.M. Jones 0ff73a42c7 generator: Implement struct FDevice type
This acts just like FString except that we do reverse device name
translation on it.  The only use is in the 'pvs-full' API where we
will use it (in a subsequent commit) to reverse translate the pv_name
field (a device name) before returning it from the daemon.

Compare this to the 'pvs' API which also returns a list of device
names, but using the generator's 'RStructList (RDevice,...)'  return
type, where RDevice is similarly reverse translated.

Note in the library-side bindings, because the name has already been
translated in the daemon, we just treat it exactly the same as
FString.  The vast majority of this patch is this mechanical change.

This program generates a large amount of code and documentation for
all the daemon actions.

To add a new action there are only two files you need to change,
'actions_*.ml' to describe the interface, and daemon/<somefile>.c to
write the implementation.

After editing these files, build it (make -C generator) to regenerate
all the output files.  'make' will rerun this automatically when
necessary.

IMPORTANT: This program should NOT print any warnings at compile time
or run time.  If it prints warnings, you should treat them as errors.

OCaml tips:

(1) In emacs, install tuareg-mode to display and format OCaml code
correctly.  'vim' comes with a good OCaml editing mode by default.

(2) Read the resources at http://ocaml.org/learn/

(3) A module called 'Foo' is defined in one or two files called
'foo.mli' and 'foo.ml' (NB: lowercase first letter).  The *.mli file,
if present, defines the public interface for the module.  The *.ml
file is the implementation.  If the *.mli file is missing then
everything is exported.

Some notable files in this directory:

  actions_*.ml        The libguestfs API.
  proc_nr.ml          Procedure numbers associated with each API.
  structs.ml          Structures returned by the API.
  c.ml                Generate C API.
  <lang>.ml           Generate bindings for <lang>.
  main.ml             The main generator program.

Note about long descriptions:

When referring to another action, use the format C<guestfs_other>
(ie. the full name of the C function).  This will be replaced as
appropriate in other language bindings.  Apart from that, long
descriptions are just perldoc paragraphs.

Note about extending functions:

In general you cannot change the name, number of required arguments or
type of required arguments of a function, since this would break
backwards compatibility.

You may add another optional argument, *if* the function has >= 1
optional arguments already.  Add it at the end of the list.

You may add optional arguments to a function that doesn't have any.
However you *must* set the once_had_no_optargs flag to true, so that
the relevant backwards compatibility bindings can be added.
