Extern keywords on function declarations/definitions provide no additional value since function declarations/definitions default to external linkage in C99, e.g. removing them won't change the semantics of the program. The extern keywords were essentially a legacy from the early days of the project. This commit cleans this up across the whole codebase in one go to minimize history disruption. The bulk of the changes in this commit were produced by a custom clang-tidy checker. Note that variables declarations carrying the extern keyword are untouched by this commit since there the presence of the keyword actually has an impact on the semantics of the program.
