Removed fcntl requirement from mavutil.py. It's unused and breaks compilation on Windows.

The function mavlink_uart_resend was added but not properly contained within a check for the MAVLINK_USE_CONVENIENCE_FUNCTIONS constant.
It is now only defined/declared when that constant is.
It has also been renamed to _mavlink_resend_uart() to match the similar _mavlink_send_uart() function.
Accidently left a test function declared. Removing.
