Make printf great again (#1438)
* Printf lib: wrap *printf* functions
* Printf lib, FW: drop sprintf. Dolphin: dump timestamp as is, wo asctime.
* FW: remove sniprintf, wrap assert functions
* Printf lib: wrap putc, puts, putchar
* Printf: a working but not thread-safe concept.
* Poorly wrap fflush
* stdglue: buffers
* Core: thread local buffers
* Core: move stdglue to thread api, add ability to get FuriThread instance of current thread.
* RPC tests: replace sprintf with snprintf
* Applications: use new stdout api
* Printf lib: wrap more printf-like and stdout functions
* Documentation
* Apps: snprintf size fixes
