d7891ce50c internal: fix XML element struct naming
We were sometimes using TitleCase, sometimes Lowercase. Let's align
on the idiomatic Go naming and pick TitleCase everywhere.

1e99b70a62 carddav: set content length header for HEAD/GET requests
Now that the backend can supply this value, use it for explicitly
setting the header in GET/HEAD responses if available.

a3e56141d9 carddav: add support for getcontentlength property
Allow the backend to provide a value for the `getcontentlength` property
as described in [RFC 2518 section 13.4][1].

The implementation treats is as optional, allthough it is a required
property per RFC. Most clients do perfectly fine without it, though.

Properly setting this in the backend makes the CardDAV collection
listable with clients that do require it, e.g. cadaver.

cabaf3268b carddav: return multistatus response on PROPPATCH
This does not implement any actual PROPPATCH logic, but makes the server
return a proper multistatus response with errors for each property
instead of a generic HTTP error.

It also adds the distinction between requests to the address book and
those to other resources. In CardDAV, only the address book itself has
properties that make sense to change via PROPPATCH. Those are responded
to with a 501, indicating that this needs further implementation.
Requests to other resources return 405 for each property, indicating
that the resources do not support PROPPATCH at all.

b0c59cdea1 carddav/caldav: use 308 for .well-known redirects
This makes it a little less ambiguous (and, in case of Go clients, a lot
easier) that clients should follow the redirect by sending the same
PROPFIND request, including body, to the new location.

See also the documentation of [http.Client.Do()][1] and the comments in
[http.redirectBehavior()][2].

Confirmed to not make a difference for Evolution and Thunderbird
clients.

6887b6b812 Support custom user principal and home set paths
Currently, the user principal path and the home set path are both
hardcoded to "/", for both CalDAV and CardDAV. This poses a challenge if
one wishes to run a CardDAV and CalDAV server in the same server.

This commit introduces the concept of a UserPrincipalBackend. This
backend must provide the path of the current user's principal URL from
the given request context.

The CalDAV and CardDAV backends are extended to also function as
UserPrincipalBackend. In addition, they are required to supply the path
of the respective home set (`calendar-home-set` and
`addressbook-home-set`). The CardDAV and CalDAV servers act accordingly.

The individual servers will continue to work as before (including the
option of keeping everything at "/"). If one wishes to run CardDAV and
CalDAV in parallel, the new `webdav.ServeUserPrincipal()` can be used as
a convenience function to serve a common user principal URL for both
servers. The input for this function can be easily computed by the
application by getting the home set paths from the backends and using
`caldav.NewCalendarHomeSet()` and `carddav.NewAddressbookHomeSet()` to
create the home sets.

Note that the storage backend will have to know about these paths as
well. For any non-trivial use case, a storage backend should probably
have access to the same UserPrincipalBackend. That is, however, an
implementation detail and doesn't have to be reflected in the
interfaces.

8cc6542f1c carddav: use partial error response on multiget failure

c4206ba616 carddav: pass If-(None-)Match to backend
This simply extends the interfaces to pass on the values if they were
used, relying on the backend to handle things accordingly.

85d2b222bb Add error type representing DAV/XML errors
Backends will need some way to signal that a precondition error occurred
(and specifying which one) without causing the server to return a 500.
This commit adds an exported function to create a specific error for
this. The existing error handling routine is slightly adapted to handle
this error in such a way that it returns the desired result.

Usage would be something like:

```
return "", carddav.NewPreconditionError(carddav.PreconditionNoUIDConflict)
```

which triggers the following HTTP response:

```
HTTP/1.1 409 Conflict.
Content-Type: text/xml; charset=utf-8.
Date: Thu, 10 Mar 2022 10:28:56 GMT.
Content-Length: 141.
Connection: close.

<?xml version="1.0" encoding="UTF-8"?>
<error xmlns="DAV:"><no-uid-conflict
xmlns="urn:ietf:params:xml:ns:carddav"></no-uid-conflict></error>
```

This response gets correctly recognized by e.g. Evolution (though it's
handling is not great).

The added error type is generic enough to be used for other stuff also.
As it is not exported (internal package), new functions for creating
such errors would have to be added.

carddav/server: set ETag and Last-Modified if available
Some clients (e.g. Evolution) will not work properly without this. It is
up to the underlying backend to actually provide this data, the headers
will only be set if it is available.
