Add a menu entry that opens USB storage.  Pressing any button will
return to the menu and disable USB storage again.

Add a mechanism for "favorite apps" which are shown at the top of the
app-list no matter what.

When a traveller has many apps installed, loading the menu takes some
time.  To give them feedback that card10 is in fact loading the menu
right now, immediately display a loading message before starting to
enumerate the app list.

Unify unrecoverable errors to use panic() in all cases.  This will allow
further changes to panic() to work for all critical errors.

Newlib assert uses __assert_func and thus our panic() function while
MXC_ASSERT uses a custom assertion logic.  Newlib assert is also more
portable as it works in expression position while MXC_ASSERT only works
as a statement.

Define `__assert_func()` so a failing `assert()` will trigger a panic.

In unrecoverable situations we should provide a common way to output the
cause of the error and then reset the CPU.  The panic() function is
mean to be exactly that.  It outputs the error-cause, stack-trace, and
firmware revision, accompanied by a link to the issue-tracker to
encourage people to report the error.  After a timeout of ~1.5s it
resets the CPU and reboots.

Future Work:

 - Right now, the stack-trace only has a depth of one which is the
   return address from where panic() was called.  In the future it might
   make sense to provide a deeper stack-trace if a robust implementation
   is possible.
 - Integration of @msgctl's faultscreen (!79) so users who don't have
   the serial console open at all times can also see what happened.

In severe error conditions, asynchronous prints will never work.  For
such cases we need a way to make prints happen synchronously again, the
same way it works during early boot.  Add a serial_return_to_synchronous()
function which unconditionally switches the serial driver code to
synchronous mode.

Only use this function in unrecoverable error conditions!

card10_reset() won't ever return to where it was called from.  Telling
the compiler this can help with program-flow analysis.

Fix two bugs in the display/gfx module:

1. The animation of the simple_menu used in the main menu had the issue
   that there is a black line visible at the top.  This is due the
   gfx_puts method ignoring lines, where the top pixel of the string is
   above the top of the screen.  As gfx_puts uses gfx_setpixel which in
   turn ignores pixels outside of the screen, remove the check in
   gfx_puts.
2. X and Y coordinates were cast to unsigned-ints before being given to
   the gfx-library which means calls like circ(0, -10, 30) would be draw
   at coordinates like [0,65526].  Fix this by changing the data-type of
   all coordinates to signed-integers.

Also remove the x and y ranges from the documentation of the individual
python functions and instead add a general documentation about the
screen and it's size/coordinate system.
