ejurgensen aaffa4a83f [jsonapi] Add support for updating queue_item metadata (closes #1153) 
This commit also changes db.c's sort_tag_create to always recreate sort tags,
so that they match source tags, should they have changed. Unclear to me why
the previous solution didn't do that, so will probably regret this change when
it dawns on me.

### Search by query language
Search for artists, albums, tracks by a smart playlist query expression (see [README_SMARTPL.md](https://github.com/ejurgensen/forked-daapd/blob/master/README_SMARTPL.md) for the expression syntax).
**Endpoint**
```http
GET /api/search
```
**Query parameters**
| Parameter | Value |
| --------------- | ----------------------------------------------------------- |
| expression | The smart playlist query expression |
| type | Comma separated list of the result types (`artist`, `album`, `track` |
| offset | *(Optional)* Offset of the first item to return for each type |
| limit | *(Optional)* Maximum number of items to return for each type |
**Response**
| Key | Type | Value |
| --------------- | -------- | ----------------------------------------- |
| tracks | object | [`paging`](#paging-object) object containing [`track`](#track-object) objects that matches the `query` |

| albums | object | [`paging`](#paging-object) object containing [`album`](#album-object) objects that matches the `query` |
**Example**
Search for music tracks ordered descending by the time added to the library and limit result to 2 items:
```shell

## Push notifications
If forked-daapd was built with websocket support, forked-daapd exposes a websocket at `localhost:3688` to inform clients of changes (e. g. player state or library updates).
The port depends on the forked-daapd configuration and can be read using the [`/api/config`](#config) endpoint.
After connecting to the websocket, the client should send a message containing the event types it is interested in. After that forked-daapd
will send a message each time one of the events occurred.
**Message**
| Key | Type | Value |
| --------------- | -------- | ----------------------------------------- |
| notify | array | Array of event types |
**Event types**
| Type | Description |
| --------------- | ----------------------------------------- |
| update | Library update started or finished |
| database | Library database changed (new/modified/deleted tracks) |
| outputs | An output was enabled or disabled |
| player | Player state changes |
| options | Playback option changes (shuffle, repeat, consume mode) |
| volume | Volume changes |
| queue | Queue changes |
**Example**
```shell
curl --include \
--no-buffer \
--header "Connection: Upgrade" \
--header "Upgrade: websocket" \
--header "Host: localhost:3688" \
--header "Origin: http://localhost:3688" \
--header "Sec-WebSocket-Key: SGVsbG8sIHdvcmxkIQ==" \
--header "Sec-WebSocket-Version: 13" \
--header "Sec-WebSocket-Protocol: notify" \
http://localhost:3688/ \
--data "{ \"notify\": [ \"player\" ] }"

### Artwork urls
Artwork urls in `queue item`, `artist`, `album` and `track` objects can be either relative urls or absolute urls to the artwork image.
Absolute artwork urls are pointing to external artwork images (e. g. for radio streams that provide artwork metadata), while relative artwork urls are served from forked-daapd.
It is possible to add the query parameters `maxwidth` and/or `maxheight` to relative artwork urls, in order to get a smaller image (forked-daapd only scales down never up).
Note that even if a relative artwork url attribute is present, it is not guaranteed to exist.
