[Libguestfs] [PATCH 1/2] mllib: add and use set_standard_options
Introduce a new common helper to add the common options for libguestfs
tools (short/long options, version, verbose, trace), and sort them.
All the OCaml-based tools had these options already, so there are no
functional changes in the interface they provide.
The only difference is that now the options are always sorted, while
some tools didn't had them like that previously: because of this, a
couple of ditto markers (as descriptions) don't match what's above them
anymore, and thus their full description is put instead.

[Libguestfs] [PATCH 2/2] mllib: set --debug-gc as common option
Move --debug-gc as common option for all the OCaml-based tools, even a
couple of them which didn't have it previously.
As implementation note, make set_debug_gc private to
set_standard_options, as it needed to be moved otherwise, and it is no
more required as public function.

Re: [Libguestfs] [PATCH 2/2] mllib: set --debug-gc as common option

I guess long_options, display_long_options and display_short_options also no longer need to be public?
