tracker issue : CF-3916425

CF rewrites file://host as file:////host. This causes exceptions and unexpected results (and potential date corruption due to directoryList() and <cfdirectory action="list" returning an incorrect number of rows).

Steps to reproduce:
1) Create C:\ticket3863993 and share it as ticket3863993
2) Create C:\ticket3863993\myfile.txt
3) Run the following code:

<cfscript>
  //These fail or return incorrect results
  writeDump(directoryExists("file://localhost/C:/ticket3863993"));//Returns NO
  q = directoryList("file://localhost/ticket3863993", true, "query");
  writeDump(q);//Directory column contains file:////localhost/ticket3863993/ instead of file://localhost/ticket3863993/
  q = directoryList("file://localhost/C:/ticket3863993", true, "query");//Throws exception: The specified directory file:////localhost/C:/ticket3863993 does not exist. 
  writeDump(q);
  //These succeed
  writeDump(directoryExists("file:///C:/ticket3863993"));//Returns YES
  q = directoryList("file:///C:/ticket3863993", true, "query");
  writeDump(q);
</cfscript>
<!--- These fail or return incorrect results --->
<cfdirectory action="list" name="q" directory="file://localhost/ticket3863993">
<cfdump var="#q#"><!--- Directory column contains file:////localhost/ticket3863993/ instead of file://localhost/ticket3863993/ --->
<cfdirectory action="list" name="q" directory="file://localhost/C:/ticket3863993">
<cfdump var="#q#"><!--- Returns 0 results --->
<!--- These succeed --->
<cfdirectory action="list" name="q" directory="file://localhost/ticket3863993">
<cfdump var="#q#">

Per http://en.wikipedia.org/wiki/File_URI_scheme, a file URI takes the form of file://host/path and host is treated as "localhost" if omitted. CF is incorrectly rewriting file://host as file:////host.
