Adding mosh, the mobile shell. Mosh uses ssh or dropbear as an initial transport to
start mosh-server which uses UDP to communicate with the client.
Supports a predictive model to enhance performance on weak connections
and compensate for general lag. Also supports disconnections and
reconnections seamlessly.

+The locale command is not available on many systems. As this variable
+is unused and appears to have been written with the intent of
+displaying the locale settings to the user, it's not really necessary.
+As this breaks Mosh on a lot of systems, it's best to remove the calls.
+
+Upstream status: refused, see: https://github.com/keithw/mosh/issues/650
