tracker issue : CF-3132537

Problem Description:
When submitting a form that contains more than one HTML5 upload field (each having the "multiple" attribute set), ColdFusion appears to mix up the number of files each field was sent and the content.  Results in not all files being present when processed with CFFile action="uploadall" and some of the files containing the wrong content (from other uploads).

Steps to Reproduce:
1. Create a form
<form method="post" enctype="multipart/form-data" action="uploads.cfm">
  <label>First: <input type="file" name="first" multiple="multiple" /></label><br />
  <label>Second: <input type="file" name="second" multiple="multiple" /></label><br />
  <label>Third: <input type="file" name="third" multiple="multiple" /></label><br />
  <input type="submit" value="Upload" />
</form>
2. Using 7 uniquely named files, select 1 file to upload to the field "first".
3. Select 2 files for the field "second".
4. Select 4 files for the field "thrid".
5. Submit the form.
6. Dump, form, form.getPartsArray(), form.getTempFiles() and use CFFile action="uploadall".

Actual Result:
* form.fieldnames held correct number of field names.
* form.third held 5 files instead of 4.
* 2 of the file names in form.third were the 2 listed in form.second.
* 5 files received instead of 7.

Expected Result:
* 7 files in the destination folder.
* form fields to contain the correct number of temporary files to uploads.
* Each upload once processed with CFFile upload / uploadAll to contain the right content.

Any Workarounds:
None, uploads are handled internally by ColdFusion.  Without a fix, HTML5 multiple uploads are broken and should definitely not be used as it'd result in lost content and incorrect file content.
