include: Add option to prefix logs with an ID
This adds the log_xxx_id() macros to print a logline prefixed with a 64-bit identifier in hex format, for instance: [2a92d78c2f52b76a] Hello ouroboros! The ID is assumed to be 8 bytes in big endian format (it uses the HASH_FMT functions and hashes are stored in big endian byte arrays). The implementation uses the compiler-specific '##' operator to allow empty variadics. E.g. func(arg , ## __VA_ARGS__); will eat the comma if __VA_ARGS__ is empty and thus allow func(arg); Signed-off-by: Dimitri Staessens <dimitri@ouroboros.rocks> Signed-off-by: Sander Vrijders <sander@ouroboros.rocks>
