    Travis: add rust cargo online mode
    
    Forward-ports parts of the 0.3.2 travis config on top of the 0.2.9
    merge.
    
    Also:
    * build rust on clang and gcc, Linux and macOS
    * build combinations of non-default options on gcc Linux
    * exclude broken builds
    * log the rustup version
    
    Part of 24629.
