[FL-781] FURI, CLI, stdlib: stdout hooks, integration between subsystems, uniform printf usage (#311)
* 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
