in repository bitbake.

commit 0ad88797fb3bdbb5c418039e194a5e1b700cb27b

    fetch2/npm: don't download same URL multiple times
    
    If we've already fetched a particular URL then we do not need to do so
    again within in the same operation. Maintain an internal list of fetched
    URLs to avoid doing that.
