The new code gets closer to an actual bootloader:
- it provides a menu with three options: Sony, Rockox, tools with icons (and
extracts the Sony logo from the NVP)
- the dualboot install script now creates a symlink from /.rockbox to
/contents/.rockox which is necessary to run rockbox
- more text drawing / framebuffer functions
In the long run, we will move this under bootloader/ and rbutil/ and also use
firmware/ drawing facilities, at the moment we use OF display program which
is slow and creates some flickering.
The logo extraction/placement code was tested with resolution 240x320 and I
guessed some reasonable values for 240x400, but those will probably need some
tweaking.

Using the database, we can now safely read/write the NVP. I also add more
support for Sony's "display" tool.

Sony added extensions to the frambuffer interface. It is important to take them
into account since the OF uses them and might leave the framebuffer in an
unusual state which would make the dualboot not display anything. Also rework
the dualboot code so that it can boot rockbox (not doing anything at the moment),
display all tools or boot the OF.

At the moment, the script install_duaboot does the following:
- rename SpiderApp to SpiderApp.of (unless it already exists)
- install payload as SpiderApp
- fixes permissions
Since SpiderApp is the main app, it will execute instead of the OF.
The current dualboot code (dualboot.c) is still a preliminary but the current
version displays an "all tools" menu to choose for. When exitting the menu
using BACK, it will run the OF.
With the modifications made by the install script, it should not be possible
to break the device. In the worst case scenario, the dualboot code crashes
and it restarted by the sysmgrd, or hangs. A safe way to recover is to plug
the USB cable and reset the device: the system manager will then start the
USB app and one can reflash the device if necessary.

This new tool (all_tools) embeds all the other tools and provides a menu to
choose which one to run.

This list can map from model id to device name. It was automatically extracted
from Sony's tools. In the future, we will probably generate it from a clean
database containing more useful information.

This is code is intended to development into a library of code for the NWZ that
will be useful to write the "bootloader" on those device. At the same time, it
comes with test programs that are easy to run in firmware upgrade mode and also
provide a great test bench for the library. At the moment, two test programs are
available:
- test_display: simply prints two messages using /usr/bin/lcdmsg
- test_keys: displays input key event
