Rygel 0.12.5 (Wolf in Sheep's Clothing)

Rygel 0.12.5 (Wolf in Sheep's Clothing) is out!

Changes since 0.12.4:

- Send proper SSDP notification when killed with SIGTERM.
- Fix out-of-tree builds.
- Prevent a crash when searching and uploading in parallel.
- Prevent a critical error when the uri to be added already exists.
- Prevent a name clash when an uploader is really fast in creating items.
- Mark thumbnail resources as transcoded. This helps certain devices to use
  them as thumbnails and not as the original stream.
- Prevent a false-positive test success in http-post-test.
- Use proper error if a client tries to get the children of a media item.
- Fix huge CPU load if a client did a lot of byte-range requests on a large
  media file.

Tracker:
 - Fall back to nfo:fileLastModified if nie:creationDate is not available.
 - Properly clean and escape any passed item ID.

MediaExport:
 - Properly disable MediaExport if Tracker start-up is slow.
