[Merge] lp:~rsalveti/telepathy-ofono/adding_support_for_hsp into lp:telepathy-ofono

[Ricardo Salveti]

Sorry, forgot to add the extra info for the changes I'm also doing in parallel with this MR.

I changed pulseaudio to handle wired headset, so you also need the latest pulseaudio packages available at silo https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/landing-008 if you want to validate the wired headset mode.
