* FURI stdglue: stdout hooks, local and global, ISR safe printf. Uniform newlines for terminal/debug output. Power: prevent sleep while core 2 has not started. * Furi record, stdglue: check mutex allocation * remove unused test * Furi stdglue: buferized output, dynamically allocated state. Furi record: dynamically allocated state. Input dump: proper line ending. Hal VCP: dynamically allocated state. * Interrupt manager: explicitly init list. * Makefile: cleanup rules, fix broken dfu upload. F4: add compiler stack protection options. * BLE: call debug uart callback on transmission complete * FreeRTOS: add configUSE_NEWLIB_REENTRANT * API HAL Timebase: fix issue with idle thread stack corruption caused by systick interrupt. BT: cleanup debug info output. FreeRTOS: disable reentry for newlib. * F4: update stack protection CFLAGS to match used compiller * F4: disable compiller stack protection because of incompatibility with current compiller * Makefile: return openocd logs to gdb * BLE: fixed pin, moar power, ble trace info. * Prevent sleep when connection is active * Makefile: return serial port to upload rule, add workaround for mac os * Furi: prevent usage of stack for cmsis functions. * F4: add missing includes, add debugger breakpoints * Applications: per app stack size. * Furi: honor kernel state in stdglue * FreeRTOS: remove unused hooks * Cleanup and format sources Co-authored-by: DrZlo13 <who.just.the.doctor@gmail.com>
