    net/http: use require_relative to reduce syscalls
    require_relative speeds up loading of files by reducing path
    lookups.  On a clean install with RubyGems-enabled,
    "ruby -rnet/http -e exit" shows a reduction in failed open(2)
    syscalls from 410 to 350 (x86-64 GNU/Linux).
    I could not measure a time difference on my Linux-based
    machines, however this should be noticeable to users of other
    kernels with worse syscall and VFS performance than Linux.
    Further use of require_relative will reduce lookups in other
    * lib/net/http.rb: use require_relative
      [ruby-core:78285] [Feature #12973]
