At present, we keep both permanent (eg links/n_links) and temporary
(event) data in struct discover_context.
This change makes discover_context a temporary structure, just used
during actual device discovery. Once discovery is complete, the
permanent data (discover_device) is "committed" to the device handler.

Currently, we assume all user events are for a new device. This means
that we can never add boot options to an existing device.
This change tries to find an existing (matching by ID) device before
creating a new one in the user event add path.

We want to cater for situations where boot options may be discovered
some time after we get notificiation about devices. For instance,
discovering boot options from DHCP configuration parameters. In this
case, we'll need to notify UIs of boot options appear some time after
the device (and/or other boot options on the same device) has appeared.
This change adds a new protocol message type,
PB_PROTOCOL_ACTION_BOOT_OPTION_ADD. We also rename
PB_PROTOCOL_ACTION_ADD to make it clear that it is just for devices.
The discover server is updated to send boot option add events at device
discover time, but we are now able to decouple this later.
We also update the clients to handle the boot option add events
separately.

Now that the server does the booting, we should move the --dry-run
argument to the server.

This change adds a funtion, device_handler_boot, which processes the
boot command message from the discover server.
We add a new file, discover/boot.c (and a corresponding header) with a
skeleton for the final kexec code.

The device and boot_option types are defined in pb-protocol.h, but
aren't really specific to the procotol. This means a lot of
non-messaging-related files are #including the protocol definitions
unnecessarily.
This change separates the types out into lib/types/types.h.

The struct udev_event can be used as a generic event, so rename it
struct event and move it from udev.h into a new file event.h.
Also, rename the emums UDEV_ACTION_ADD and UDEV_ACTION_REMOVE
to ACTION_UDEV_ADD and ACTION_UDEV_REMOVE.
