Radicale

* Fix the owner_write rights rule

One feature in this release is **not backward compatible**:

* Use the first matching section for rights (inspired from daald)

Now, the first section matching the path and current user in your custom rights
file is used. In the previous versions, the most permissive rights of all the
matching sections were applied. This new behaviour gives a simple way to make
specific rules at the top of the file independant from the generic ones.

Many **improvements in this release are related to security**, you should
upgrade Radicale as soon as possible:

* Improve the regex used for well-known URIs (by Unrud)
* Prevent regex injection in rights management (by Unrud)
* Prevent crafted HTTP request from calling arbitrary functions (by Unrud)
* Improve URI sanitation and conversion to filesystem path (by Unrud)
* Decouple the daemon from its parent environment (by Unrud)
