Here follows the patch to make PHP handle file uploads done usning HTTP PUT
method.

Basically it does the following:

* Checks content length against PHP maximum upload size option.
* Creates a file in the directory defined in PHP upload directory option.
* Reads the file data and writes it to the temporary file.
* Sets the global variable PHP_UPLOADED_FILE_NAME to the uploaded temporary file.
* Schedules the file to be deleted on PHP exit.
