Adds an option to write a btsnoop compatible log file containing BLE
traffic. A new file is created after each boot if BLE is activated and
the `ble_log_enable` option is set in `card10.cfg`. The last 10 logs are
kept via log rotation.

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.

Disable the `unused-parameter` warning for the mpy-cross-wrapper to
silence an error about `argc` being unused (which is ok).

As discussed in card10/firmware!357

, we should increase the number of
enabled compiler warnings to catch a lot more silent bugs.  Increase the
meson-global warning level to 2, but excluding the `unused-parameter`
and `old-style-declaration` warnings.  Additionally, disable warnings
for libraries as we cannot fix that code anyway.

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.

Previously, we left out the dependency of the QSTR header on
`modules.h`.  This was done to prevent rebuilds of the entire
MicroPython sources whenever a Pycardium module is changed. This
leads to issues where QSTRs got out of sync and weird errors like
the following could happen:

    import foo_module

    Exception: No module `abc_def` (a different string than expected)

Attempt to fix this by only updating the QSTR header when the
module-header actually changes.  For this, a few workarounds are needed:

- Replace symlinks with actual copied files so timestamps change on
  updates.
- Add a hack so meson picks up on the dependency of the file in genhdr/
- Rename the outer file so older meson versions don't complain about
  multiple targets with the same name.

When MXC_ASSERT is disabled, the portexpander_config() call is not
compiled into the bootloader which leads to the portexpander not being
setup correctly and thus neither the screen turns on nor does the button
to switch into MSC mode work correctly (bootloader always goes into MSC
mode).

Fix this by moving the portexpander_config() call outside the MXC_ASSERT
and only keep the return value check inside.  Additionally fix the
pull-up/pull-down selection in portexpander_config() not being set
correctly.

actual chinese text.

Copying the list of characters in the same order of font24CN.c into
