- Update to version 1.5.0
* Added smbprotocol.exceptions.SMBConnectionClosed that is
raised when trying to send or receive data on a connection
that has been closed.
* Added smbprotocol.exceptions.WrongPassword that is raised when
some servers indicate the password is not correct or the
account is locked out.
* Do not attempt to reuse any cached connections that have been
closed in smbclient
* Added a lock when writing to the socket, only 1 thread can
write a message at a single point in time
* Revamped the SMB receiver code to simplify the logic and make
it more durable
+ Removed the TCP recv thread for each connection, now each
connection uses just 1 thread instead of 2.
+ Be more defensive when reading data from a socket to ensure
we get all the data we require.
+ Handled server side FIN packets that close the connection
unexpectedly, any requests waiting for a response will
raise SMBConnectionClosed.
