c34a8731b6 Data row value slices need to be capacity limited 
Otherwise, appending to a slice that came from a data row could
overwrite adjacent memory.

595780be0f Map io.EOF errors to io.ErrUnexpectedEOF 
io.EOF is never expected during valid usage. In addition, database/sql
uses io.EOF as a sentinal value that all rows from a query have been
received.

1c20e7d36e Fix malformed SASL messages 
Per the PG documentation [0], an AuthenticationSASLContinue message has:

    AuthenticationSASLContinue (B)
	Byte1('R')
	    Identifies the message as an authentication request.
	Int32
	    Length of message contents in bytes, including self.
	Int32(11)
	    Specifies that this message contains a SASL challenge.
	Byten
	    SASL data, specific to the SASL mechanism being used.

The current implementation was mistakenly adding the lengh of msg bytes
in between the Int32(11) and Byten. There was a similar issue for
AuthenticationSASLFinal.

b3d0cbd0e6 Fix reading interrupted messages 
When an message is received and a timeout occurs after reading the
header but before reading the entire body the connection state could
be corrupted due to the header being consumed. The next read would
consider the body of the previous message as the header for the next.

fixes #348
