move telemetry into master

Alex would rather replace this implementation by a rock-webapp based one.
move the 'next' packages into 'stable'
prepare synchronize 'stable' with rock1408

'next' disappears in this release. It is now an alias to 'stable'
replace the deprecated ROCK_FLAVOR variable by ROCK_BRANCH
latest release is rock1408
add a special source file only for stable

With source-master.yml, autoproj would bail out if trying to
checkout master-only packages (as their version control definitions
did not get loaded). This commit moves the master into source.yml
(as "default") and the stable into an extra file
move base/orogen/interfaces to stable, it is required by the rock1408 branches

Janosch forcefully pushed the relevant changes. Great to move
never-released deprecated code into a release
make the use of source-stable.yml dependent on the availability of the autoproj feature
fix over-eager "switch back to master" behaviour
fix rice installation

rice requires autoconf to be installed, so make sure it is

don't misrepresent our capabilities

This flavor implementation cannot freeze rock1408 completely, so don't
pretend that we can
cleaned the source.yml

there were some missing dependencies on sylvain's github account.
