Subject: Introduce URI::File to handle file URI scheme

* the default value of URI::File's authority is "" (localhost).
  Both nil and "localhost" is normalized to "" by default.
* URI::File ignores setting userinfo and port

+  # The "file" URI is defined by RFC8089
+  #
+  class File < Generic

+    DEFAULT_PORT = nil

+    # == Description
+    #
+    # Creates a new URI::File object from components, with syntax checking.
+    #
+    # The components accepted are +host+ and +path+.
+    #
+    # The components should be provided either as an Array, or as a Hash
+    # with keys formed by preceding the component names with a colon.
+    #
+    # If an Array is used, the components must be passed in the order
+    # [host, path]
+    #
+    # If the path supplied is absolute, it will be escaped in order to
+    # make it absolute in the URI. Examples:

+    #     require 'uri'
+    #
+    #     uri = URI::File.build(['host.example.com', '/path/file.zip'])
