Libguestfs - Jan 2023 - [p2v PATCH 02/11] Introduce "p2v.output.misc" for passing "-oo" options to virt-v2v

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1792141

Let the user pass "-oo" options from the kernel cmdline and from the
GUI
to virt-v2v.  This is primarily useful with the OpenStack output mode,
so reenable that mode.

The argument for virt-p2v's "--cmdline" option has grown huge.
Break it to
multiple lines. That's easiest to do with a shell array.

From: Alban Lecorps <alban.lecorps at ubisoft.com>

The "-oo" option will be useful primarily for the openstack output
mode
(currently disabled, from commit b74c126629e3, "Ignore 'openstack'
driver", 2020-03-16).

Use a ConfigStringList knob for "-oo", and for each OPTION=VALUE
element
in that list, create a separate "-oo OPTION=VALUE" option. Do this
because
there are too many "-oo" options, and because they are
output-dependent,
and because even virt-v2v "blindly" forwards some of those (such as
"-oo
os-*=*" for openstack).

The "p2v.oo" shorthand is not needed for compatibility, but it's
still a
good idea for user convenience.

(Various tweaks, documentation, and test case update, by Laszlo.)

 /**
  * Split string at separator character C<sep>, returning the list of
  * strings.  Returns C<NULL> on memory allocation failure.

Some of the overlong lines in "gui.c" originate from function calls
like

  config->whatever = strdup (gtk_entry_get_text (GTK_ENTRY (entry)));

These are hard to wrap -- we generally break the second and further
arguments in a function call to new lines, and start those new lines
aligned with the opening parenthesis of the function call. However, in the
above expression, each function only takes one parameter -- the problem is
the deep nesting, and our wrapping style generally strives to reflect
nesting.

Extract the expression to a small (somewhat accidental) helper function.
This function is then used from multiple dialogs (the connection dialog
and the conversion dialog).

In "gui.c", we use many long string literals, for labels, warnings,
tooltips etc. Wrap them so the source code never exceeds 80 characters in
width.

Introduce a new GTK_ENTRY field in the Output options box.  Similarly to
"p2v.output.misc" on the kernel cmdline, the contents of this
GTK_ENTRY
are a comma-separated list of OPTION=VALUE options, where each option is
passed to virt-v2v as the argument of a separate "-oo" option.

Refresh the manual accordingly.

For initially populating the text entry (in case the kernel command line
specified "p2v.output.misc"), call the guestfs_int_join_strings()
function
that we imported previously in this series.

For unpacking the contents in start_conversion_clicked(), call
guestfs_int_split_string(), just like the generated kernel cmdline parser
does, in update_config_from_kernel_cmdline() [kernel-config.c].

 All output options and paths are relative to the conversion server
 (I<not> to the physical server).

With "-oo" exposed on the GUI, the reason for disabling the openstack
driver (from commit b74c126629e3, "Ignore 'openstack' driver",
2020-03-16)
is gone. Reenable the driver.

At the same time, add two small openstack-related hints to the GUI.
