Add typedef for putc1, fn_putc1_t. (#6550)

Browse Source 
* Add typedef for putc1, fn_putc1_t.
Replaced relevant usage of `(void *)` with `fn_putc1_t`.
Correct usage of `ets_putc()`, returning 0, in libc_replacement.cpp
This PR assumes PR https://github.com/esp8266/Arduino/pull/6489#issue-315018841 has merged and removes `uart_buff_switch` from `umm_performance.cpp`
Updated method of defining `_rom_putc1` to be more acceptable (I hope) to the new compiler.

* Use PROVIDE to expose ROM function entry point, ets_uart_putc1.
Added comments to ets_putc() and ets_uart_putc1() to explain their
differences. Change prototype of ets_putc() to conform with fp_putc_t.
Updated _isr_safe_printf_P to use new definition, ets_uart_putc1.
