Pull Request Overview
This pull request adds comprehensive documentation and addresses linting issues across the MinUI codebase. The changes focus on documenting C code with detailed function-level and file-level comments, particularly for platform-specific implementations and hardware abstraction layers.
Key Changes:
- Added detailed file and function documentation throughout the codebase
- Fixed minor linting issues (unused variables, missing return statements, format specifiers)
- Consolidated utility headers from multiple files into a single utils.h
- Removed interactive TTY flags from Docker commands in makefile

[nitpick] Assignment chain has_jack = had_jack = JACK_enabled() should be written as two separate assignments for clarity: had_jack = JACK_enabled(); has_jack = had_jack;

Using %u format specifier for uint32_t is not portable. Use PRIu32 from <inttypes.h> or cast to unsigned int for guaranteed correctness.

Comment states 'Should never reach here' but function can reach this return statement when neither swap_val condition is true. Either remove the comment or add an assertion to validate the assumption.

[nitpick] Variables i and p are declared but not initialized. While they are assigned before use, initializing to 0 would make the code more defensive.

Parameter 'argc' is declared but never used in the function body. No bounds checking is performed on argv before accessing argv[1], which could cause a crash if the program is called without arguments.

Function signature in header uses 'const char*' but implementation may use 'char*'. Ensure consistency between declaration and definition.

[nitpick] Removed -it flags from docker run commands. These flags enable interactive terminal mode which is useful for debugging. Consider documenting why non-interactive mode is preferred or provide a separate target for interactive debugging.
Address common linting issues and thoroughly document all the C code.
