19800	Media & WXR Uploads: Inaccurate error reporting because move_uploaded_file() fails to return false.	emhr	duck_	"Steps to reproduce: 
Current month directory exists in uploads directory hierarchy but is not writable.

Case-1 Upload a new media item. Data stored in database but file is not uploaded.

Case-2 Upload a WXR import file using the WP importer plugin. Plugin reports it's fallback error message: ""This does not appear to be a WXR file, missing/invalid WXR version number"" even if the WXR file has a valid wxr version number. The import fails.

Expected behavior: 
The uploader should return the following error, ""The uploaded file could not be moved to""…path

Solution: 
Pass precise path to wp_tempnam() instead of default
