- Add an optional line number to the 32-bit log tokenized payload.
- Update default payload field widths.
Log level: 3 bits
Line number: 11 bits (up to 2047, 0 if larger)
Flags: 2 bits (implementation defined)
Module token: 16 bits
- Use the maximum log level to indicate that a log is an assert. This
preserves an additional bit which can be used for the flags or line
number.
- Store data as key-value pairs in the format string.
- Reorganize pw_log_tokenized tests and add C tests.
