fw: No .data or .bss segment
We don't use any .data or .bss segment at all to keep all the firmware
variables in the stack in protected fw_ram.

fw/testfw: Use fw_ram for firmware stack
This means firmware's stack shouldn't be accessible to programs
running in app_mode.

It also means we don't need to take special care of secure_ctx which
can now be an ordinary stack variable.

Nonetheless we zero out secure_ctx after final use and inline some
assembler to zero out the entire fw_ram after use, just before
switching to app_mode.

fw: Use a bit string for allowed_commands
For every state, define a constant bitstring with allowed commands and
check incoming command agains that.

fw: Remove state init_loading, introduce state fail
- We always assert on allowed commands in a state.
- We don't allow FW_CMD_LOAD_APP to be used twice.
- Enter fail state on read buffer overrun, header endpoint not for us,
  header parse error, and unknown firmware command.

fw: Use byte readable UDS
UDS is now byte readable (but not writable).

Use UDS and USS directly in a blake2s_update() instead of
concatenating them into fw_ram. UDS will still live for a short while
in fw_ram in the blake2s context buffer but will soon be overwritten.

testfw: Use wordcpy_s() and memcpy_s()
Use new wordcpy_s() and memcpy_s() functions from lib.c.

Add a local memcpy() which compiling with -Os seems to demand. Why?

fw: Hide HTIF functions better when using NOCONSOLE
We define macros for them that expand to nothing or to a constant to
avoid any extra function calls to dummy functions when running on real
hardware with no console.

fw: Safer memory functions + asserts
Introduce memcpy_s() and wordcpy_s() that takes the destination buffer
size as an argument. Use assert() which aborts our program to an
eternal loop if we hit problems.

Sprinkle asserts elsewhere as well.

Add (hardware) production tests for the TK-1 and TP-1 (#69)
* ch552 firmware: add ch55x support files directly

* Add sdcc compiler to docker image, for building CH552 firmware

* Rework production test script

* Add menu-based test runner
* Rewrite production test flows as lists of individual tests
* Add both production flows and manual tests to menu

* Switch to using included binaries

* production test: Update message format
* test_txrx_touchpad: Retry if device communications fail
* production test: put all binaries in binaries/ folder
* binaries/top.bin: replace broken binary

* flash_check: Check for explicit flash IDs

* Document most test procedures

* Test plan documentation

* Sample udev rules

* Production test: allow external references to be overridden

* Remove outdated descriptions

* Correct shebang

* Update shebangs to comply with PEP 394

Change the python scripts to call python instead of python3, as this
works cross platform. See:
https://peps.python.org/pep-0394/#for-python-script-publishers

* Move production test to higher-level directory

* Clarify production test setup

* Move USB C connector test to separate directory
