Ivan Grokhotkov 0713a01db8 Fix iostream related issues (#5047) ...

* add stubs for more exception throw calls

Fixes https://github.com/esp8266/Arduino/issues/3358

* libc: make putc_r implementation weak

newlib provides its own implementation of _putc_r, which will call
_write_r (possibly after buffering). Make our implementation weak to
allow using the one from newlib.

Fixes https://github.com/esp8266/Arduino/issues/4630

* libc: fix incorrect return value of _write_r call

Should return number of bytes written, actually returned zero. This
resulted in std::cout going into failed state after the first write.

* tests: add test for output to std::cout
