* 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
