Subject: [PATCH 1/6] Update Serial.h for 9-bit support
Added to write function declarations for functions being added to the serial.cpp to support the 9-bit functionality of the processor.
The "bool wake" allows turning on the 9-bit, also known as the wake bit.

Subject: [PATCH 2/6] Update Serial.cpp to support 9-bit functionality on UART
Add two functions and the supporting 9N1 case logic to allow for turning on 9-bit support and sending commands. The second argument, bool, allows for turning on or off the 9th bit, also known as the wake bit.
Serial1.begin(19200, SERIAL_9N1);
Serial1.write_9bit(0x81, true);
Serial1.write_9bit(&temp[1], false, len - 1);

Subject: [PATCH 3/6] Update Serial.cpp
I removed two unnecessary functions that I added with this pull request to turn on 9bit. There was a little code cleanup /refactoring.
