* Fixing compiler warnings with -Wextra * More warnings suppression, WIP * Even more warning fixes * Added new lines at end of text files. * Padding fix * Additional fixes to warnings on different build configurations; added -Wextra to default build pipeline * Fixes for Secplus v1 * -additional warnings * +-Wredundant-decls fixes * FuriHal: print stack overflow task name in console * FuriHal: add missing include Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
