Introduces a small state machine which parses the file character by
character. This eases the logic around parsing whole lines
significantly.

Now also trims lines, handling all non printable characters correctly.

Get samples from FIFO by small junks due to a recommendation from Maxim
not to read the entire FIFO, but rather a fixed number of samples.

Fix LED mutex stuff

leds_update_power() internally accesses the I2C bus so calls to this
function need to be inside an I2C lock section.

Instead of an ugly hack where spaces are used to pad the entries
background colors, properly draw a rectangle and the text above
it.  No visual change.

Currently, panics will silently reboot if the user doesn't happen to
look at the serial console when it happens.  To give a bit more
feedback, display @msgctl's faultsplash and the panic messages as well.

Originally, commit 1a3dfad3 ("fix(bhi160): Fix interrupt behavior
during initialization") was supposed to fix the BHI160 axis-mapping
issue (see card10/firmware#133) but apparently on some devices it still
needs the original hack to work.  Revert the removal of the axis-mapping
hack from commit 2f56ff36 ("fix(bhi160): Call bhy_mapping_matrix_set
twice for the first time").

The mac Adress was printed in the wrong order, BLE stroes the MAC
address in LSB first mode, different from Ethernet which uses MSB first
mode.

Instead of setting these values to 0, use the same settings as used in
lib/sdk/Libraries/BTLE/stack/ble-host/sources/stack/cfg/cfg_stack.c from
the Cordio SDK instead of 0.

In my small test these value sare not use in the normal pairing process,
so I think this is not fixing any problem.
