    [SoupURI] further fixes to CRLF-stripping
    
    The original code mistakenly assumed that strcpy() can take
    overlapping arguments, but that's not guaranteed. Rewrite to do a
    single pass over the string rather than potentially multiple
    strcpy/memmoves.
    
    Fixes "make check" on x86_64.
