kernels and related blobs
This can be used to implement a form of organization-controlled secure boot,
whereby kernels may be loaded from a variety of sources but they will only
boot if a valid signature file is found for each component, and only if the
signature is listed in the /etc/pb-lockdown file.

Several screens in petitboot-nc require an update if a config or sysinfo
update is received. However if those screens exist but are not the
current screen they will incorrectly try to draw to the screen.
Where the currently active screen is a textscreen (eg. a help screen)
the update is delayed until after the screen is exited.
In the particular case of nc-config where the current screen can be an
nc-subset screen, the nc-subset screen is exited immediately so the
update can be performed, since the nc-subset screen depends on the
information in the previous screen.

The localisation of 'OK' is cut short in a few languages by a character
or two - adjust the buttons in each affected screen slightly to
accommodate.

All current *_post() methods in ui/ncurses call redrawwin() and
wrefresh() together. wrefresh() updates any lines on the screen that
have been marked as changed or invalid. However redrawwin() marks the
entire screen as invalid unconditionally. We can reduce the amount of
data written to the screen by avoiding calls to redrawwin().
Screen transitions are the primary use case of redrawwin(), where the
whole screen must be invalidated to avoid stale data remaining on
screen. All other 'in-screen' updates such as changes to widgets or
changing focus do not require a call to redrawwin(). The most noticeable
performance improvement is in nc-menu, which makes an unnecssary call to
redrawwin() after every addition to the boot option menu.
eg. The number of bytes written to STDOUT in the main menu:

A boot option requires an image path at minimum. If an option is
created without an image, trying to edit the resulting user item causes
a segfault. Prevent the user from creating a boot option without at
least an image path.

Because it's initialised statically, help text won't be directly
gettext()-ed. Instead, we need to perform the gettext translation at
runtime, and pass untranslated strings into the help_screen code.
Instead of trusting callers to pass the untranslated strings though, we
encapsulate the help text data into struct help_text, so we know we have
an unstranslated string.

This change is a small cleanup of the key bindings; we ensure that the
general key bindings are available (and documented) on all screens.
In order to keep things consistent, this change adds an initial UI
guidelines text file, which documents the general key bindings.

We're seeing the following in the boot editor:
image: (null)ftp://...
the (null) is due to the sep in conditional_prefix, which should be
blank, not NULL.

Like the config editor, draw the boot editor into a pad instead of
directly into the sub window. This means that long device lists will be

The boot-editor API is a little more exposed than it needs to be: the
boot_editor struct does not need to be available to other files, and the
init function and on_exit functions differ from those provided for the
config and sysinfo screens.
This change unifies the boot_editor API with those for the other
screens.

Currently, when creating new menu entries, we create an empty item, add
it to the menu, then run the boot editor. This means that cancelling the
edit will leave an empty item in the menu.
This change defers the creation until the boot editor is done. To do
this, we modify the on_open callback to take a menu rather than an item,
and pass NULL boot data to the editor.

For a more portable build system convert to using the
autoconf-archive AX_WITH_CURSES macros. Allows building
on openSUSE, which has a different header file layout than
other distros, and fixes menu entries with UTF-8 characters;
this causes fedora installs (codename "Schrödinger´s cat")
to break the UI.
