mosh: new package 



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.

[Thomas:
  - Add missing dependency on host-pkgconf, as noticed by Yann
    E. Morin.
  - Indicate that openssh/dropbear is a runtime dependency.
  - Pass some variables in the configure environment to tell that SSP
    support is not available when it isn't. Otherwise, it misdetects
    the SSP support as being available, causing a build failure.]

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.
