treewide: ISO C / pedantic compliance

 - Shuffle typedefs to avoid need for non-compliant forward declarations
 - Fix non-compliant empty struct initializers
 - Remove use of braced expressions
 - Remove use of anonymous unions
 - Avoid `void *` pointer arithmetic
 - Fix several warnings reported by gcc -pedantic mode and clang 11 compilation
