* Furi HAL: memory protection unit * Core: prohibit NULL dereferencing, even for reads. * Applications: fix NULL dereference * Core: stack protection by MPU * MPU: stack region alignment * Apps: fix null pointer dereferences * Threads: fix non-null arg check * Desktop settings: fix null pointer dereference * Core: documented null-check hack * Fix null dereference issues * Apps: args check * Core: naming fixes * format code * Core: remove NONNULL specifier * FurHal: move MPU initialization to begining, fix enum naming Co-authored-by: あく <alleteam@gmail.com>
