We need a couple of automake options to prevent errors when regenerating
Makefile.ins during source preparation.
Some makefiles assume GNU make, so add 'foreign' where necessary. Also,
we are building objects in subdirectories, so we need 'subdir-objects'.

Currently, we start udhcpc with the '-n' argument, which means they'll
exit if no lease is obtained.
We'd prefer to leave the DHCP client running, so that any
slow-to-initialise links are not left deconfigured.

Currently, we have a bug when parsing zero-length files: we subtract one
from the length to exclude the trailing NUL (added by read_file), but a
zero-length file will result in a length of -1.
This change adds an explicit exit if we're attempting to parse an empty
file.

Currently, we have a bug when a boot task with more than one load tasks
is cancelled:
1) boot_cancel calls cleanup_cancellations, which performs a
load_url_async_cancel on all load tasks. This sets the load tasks'
states to LOAD_CANCELLED, and signals associated processes.
2) The first load task process completes, we get a load_url_process_exit
callback. This then invokes cleanup_cancellations.
3) cleanup_cancellations then (incorrectly) frees the boot task (and
hence freeing all pending load tasks) as no load tasks are in LOAD_ASYNC
state (we set them all to LOAD_CANCELLED in step 1)
4) The actual completion for the second load task attempts to reference
the now-freed task structure.
This change fixes the issue by handing the LOAD_CANCELLED state properly
- if we find a load task in this state, we consider the boot task still
pending, and delay the free until all loads are complete.

Petitboot environments will probably want a basic terminfo defintion
(eg, vt220) rather than a full linux or xterm, but vt220 and friends
don't define a backtab key. Backtab can be useful for proper form
navigation, and without a key definition, we just get an escape, which
exits the current screen.
This change provides a static definition for KEY_BTAB, so we should
always have one available.

Fields without O_STATIC can "scroll" horizontally, and we may miss a
left-hand section of text from the current display. This can mean that
the user can't leave a validated field with no indication why, if the
off-to-the-left data is not a valid entry.
This change adds a widgetset function to mark a field as fixed-size, so
we don't have this scrolling behaviour. This means that the entire field
contents will always be visible, and any validation errors can be seen.

We get a couple of uninitialised var warning when compiling with certain
CFLAGS (-fprofile-arcs -ftest-coverage at this stage).
In statement_if_execute: We'll never actually use this uninitialised (as
there must be at least one conditional in the parsed statement), but we
should address the warning nonetheless.
As passed to strtok_r: strtok will initialise this, but it isn't obvious
to the compiler.

ncurses' new_item() expects the name parameter to be a "printable
string", by converting it to a wchar *, and checking that each character
is printable with iswprint(). If it fails, we won't see a boot option at
all.
This change introduces a function to convert the label into something we
know is printable, and valid UTF-8. If mbstowcs fails, we replace it
with a generic 'Invalid option' label. If we encounter a valid multibyte
string with unprintable characters, we replace those with U+fffd
REPLACEMENT CHARACTER.

Currently, pemnu_destroy is used to free items. This means that the menu

Currently, the menu item creation is has two main functions:
pmenu_item_alloc and pmenu_item_setup. The latter does initialisation
(it sets item->name), and inserts the item into the menu. We have
pmenu_item_init to combine this into one, but that means we need to do
further initialisation (eg, to set on_execute) after the item has been
added to the menu.
Instead, this change use a more direct _create and _insert interface.
Create does the allocation and initialisation, while _insert does the
actual insertion.
This means new_item failures will be detected at creation time, rather
than during pmenu_insert. Also, we're now insert a completely-populated
item into the menu, rather than populating on_edit, on_execute and data
after insertion.
Because we can detect errors from creation (ie, from new_item failing),
we add handling code to cui_boot_option_add and cui_boot_editor_on_exit.

Currently pmenu_item_setup may free its item parameter on error.
This makes it non-obvious whether the item is still allocated on exit to
the caller.
Instead, this change removes the talloc_free, and requires that the
caller do this on error. This makes the potential use-after-free in
cui_boot_editor_on_exit obvious, so we fix that too.

Commit aa530148 introduced a priority member to struct boot_priority,
but didn't update the protocol deserialise function to properly decode

uninitialised, and getting invalid values in the initialised part.
This change updates the config deserialise function to do proper
handling for boot priority data.

Currently, we need to compile with -DDEBUG to implement debug-level
logging in the UIs and discover server.
Since we may not be able to easily replace a system's petitboot
binaries, this change introduces a -v|--verbose option to the discver
server and ncurses UI, which enables debug at runtime. We also move some
of the udev debug code out of an #ifdef DEBUG block.
Since petitboot is generally started on boot, we also add a little
infrastructure to pass -v to petitboot on certain system contitions:
either petitboot.debug on the kernel command line, or a petitboot,debug?
NVRAM property containing the value 'true'.

When we have multiple ncurses UIs running, we'd like to log to separate

Currently, changes to settings doesn't take effect while the discover
server is running. This means we need to reboot for any changes (eg, to
network settings) to take effect.
This change introduces a reinit path. Triggered by a configuration
update, this will cause the device handler to drop all of its devices
(and boot options), and restart the discovery process from the device
sources.

Currently, the pb-discover main() function initialises the device
handler and the device sources.
We want to eventually be able to re-init the device sources, which will
be initiated by the handler. In this case, the handler will need
references to the sources.
This change moves the creation of the device sources to be internal to
the handler. This way, the device handler gets a reference to
everything, without having to pass pointers around in main().
We also remove the _destroy functions, as we handle everything through
talloc destructors, as all sources are parented to the handler. We also
change user_event_init and udev_init to take the handler as the first
('context') argument, to make them consistent with network_init.

We used to use the mount binary to do filesystem autodetection. Since we
now know the fstype, we may as well call the mount syscall directly.
We add a log messages too, as we'll no longer get the 'running process:'

issues.

Currently, we don't hand any -t option to mount, as we expect the mount
binary to do autodetection of the filesystem type for us.
Turns out this isn't great with busybox mount, (which we're likely to be
using in petitboot builds), which implements "autodetection" by trying
the mount() syscall with every fs type in /proc/filesystems, until one
succeeds.
We expect a lot of the mount calls to fail, as we currently try to mount
everything (and abort discovery on devices that don't mount), including
non-filesystem partitions. On a test machine with 560 block devices, and
37 entries in /proc/partitions, this results in around 20,000 calls to
mount().
A better way would be to pass a -t option to mount. It turns out that
udev uses libblkid to probe the filesystem type, which is available in
the ID_FS_TYPE property. This change only attempts to mount filesystems
with this property, and passes an explicit fstype to the mount binary.

Currently, we enumerate udev devices before setting up our monitor. This
means that we may lose devices that udev discovers after we start the
enumeration, but before the monitor is registered.
This change enables the monitor before enumeration, so we don't lose
devices. We add a filter to the enumeration code to only parse
completely initialised devices.
This means we may need to handle change events as the main source of
device notifications. We keep the existing CDROM event handler, but
check for new devices and handle those as an add.

Currently, if the read-only mount fails during device discovery, we
