4765adc1a3 Use NewHTTPError to return better errors 
That function is merged upstream, but the current version still depends
on some stuff not yet merged into upstream go-webdav.

001917295d Add CalDAV support, refactor 
The filesystem storage backend now implements the required functions to
act as a basic CalDAV server. Some refactoring was done based on the
go-webdav development: introduce a UserPrincipalBackend, a new function
to serve the user principal URL, and more. See this PR for lots of
details: https://github.com/emersion/go-webdav/pull/62

Also adds a simple facility for debug output.

5728f1ee27 Make sure clients cannot overwrite address book 
Tighten the regex for valid resources and change the name of the default
address book file so that it is not covered by that regex. This will
prohibit clients from accidentally or maliciously PUTing to that file.

e5db18e289 Remove stat call from happy path 
Just try to read the file, use it if it works. Only if the file does
not exist, create default address book and try again.

78bd2a9b84 Keep context keys private 
Instead, offer type safe accessors, as documented here:

07c19a6f6c Use base64 encoded user name as their base dir 
This is safe in all circumstance and leaves it up to the auth backend to
use whatever name they like for authentication.

1d50d6dad8 Harden mapping from request path to FS path 
Put strict checks in place to avoid authenticated users accessing files
outside of their actual storage directory. These checks will need
updating if multiple address books are to be supported.

8b46585109 storage/filesystem: implement more operations

feature-complete. Simple operations work, e.g. via Evolution.
