added ivi-extension-protocol library

this library takes care to generate header and source files
from XML files.
All generated files are now stored in the build directory.

ilmCommon and weston-ivi-shell now just use the new library and
don't care about code generation any more.
In addition, a lot of duplicated code compilation is removed, resulting
in faster builds.

This patch also fixes an issue, that file generation was done every
time a build was started. This resulted in full rebuilds all the time.
