Add support for repeated starts in slave mode
...
From the data sheet TXCOMP is only set after a stop or repeated start
and address change, but EOSACC is set for a stop or repeated start when
the address remains the same. This change removes the check for TXCOMP
when not idle, to support repeated starts for both RX and TX.

Remove steps to disable pull ups as they are not needed
...
The Due has external pull-ups on the SDA0 and SCL0, and PIO_Configure
in Wire*_Init does not enable then.

SAM Wire: fixed NACK/timeout behavior of requestFrom() and available()
...
"readed" is no longer incremented in requestFrom() if
TWI_WaitByteReceived() gets a NACK or times out. This corrects the
behavior (return values) of requestFrom() and available() to match the
Arduino reference. Fixes arduino/Arduino#1311
