zcbor v. 0.9.0

zcbor_simple_*() functions have been removed to avoid confusion about their use. They are still in the C file because they are used by other functions. Instead, use the specific functions for the currently supported simple values, i.e. zcbor_bool_*(), zcbor_nil_*(), and zcbor_undefined_*(). If a removed variant is strictly needed, add your own forward declaration in your code.
Code generation naming:
- More C keywords are now capitalized to avoid naming collision. You might have to capitalize some instances if your code was generated to have those names.
- A fix was made to the naming of bstr elements with a .size specifier, which might mean that these elements change name in your code when you regenerate.

zcbor v. 0.8.0

(copied after the fact from Zephyr 3.6.0 migration guide)

If you have zcbor-generated code that relies on the zcbor libraries through Zephyr, you must regenerate the files using zcbor 0.8.1. Note that the names of generated types and members has been overhauled, so the code using the generated code must likely be changed. For example:
- Leading single underscores and all double underscores are largely gone,
- Names sometimes gain suffixes like _m or _l for disambiguation.
- All enum (choice) names have now gained a _c suffix, so the enum name no longer matches the corresponding member name exactly (because this broke C++ namespace rules).
The function zcbor_new_state, zcbor_new_decode_state and the macro ZCBOR_STATE_D have gained new parameters related to decoding of unordered maps. Unless you are using that new functionality, these can all be set to NULL or 0.
The functions zcbor_bstr_put_term and zcbor_tstr_put_term have gained a new parameter maxlen, referring to the maximum length of the parameter str. This parameter is passed directly to strnlen under the hood.
The function zcbor_tag_encode has been renamed to zcbor_tag_put.
Printing has been changed significantly, e.g. zcbor_print is now called zcbor_log, and zcbor_trace with no parameters is gone, and in its place are zcbor_trace_file and zcbor_trace, both of which take a state parameter.
