[bugfix] Fix Swagger spec and add test script (#2698) 
* Add Swagger spec test script

* Fix Swagger spec errors not related to statuses with polls

* Add API tests that post a status with a poll

* Fix creating a status with a poll from form params

* Fix Swagger spec errors related to statuses with polls (this is the last error)

* Fix Swagger spec warnings not related to unused definitions

* Suppress a duplicate list update params definition that was somehow causing wrong param names

* Add Swagger test to CI

- updates Drone config
- vendorizes go-swagger
- fixes a file extension issue that caused the test script to generate JSON instead of YAML with the vendorized version

* Put `Sample: ` on its own line everywhere

* Remove unused id param from emojiCategoriesGet

* Add 5 more pairs of profile fields to account update API Swagger

* Remove Swagger prefix from dummy fields

It makes the generated code look weird

* Manually annotate params for statusCreate operation

* Fix all remaining Swagger spec warnings

- Change some models into operation parameters
- Ignore models that already correspond to manually documented operation parameters but can't be trivially changed (those with file fields)

* Documented that creating a status with scheduled_at isn't implemented yet

* sign drone.yml

* Fix filter API Swagger errors

* fixup! Fix filter API Swagger errors

A helper to merge structs and maps in Golang. Useful for configuration default values, avoiding messy if-statements.
Mergo merges same-type structs and maps by setting default values in zero-value fields. Mergo won't merge unexported (private) fields. It will do recursively any exported one. It also won't merge structs inside maps (because they are not addressable using Go reflection).
Also a lovely [comune](http://en.wikipedia.org/wiki/Mergo) (municipality) in the Province of Ancona in the Italian region of Marche.
## Status
It is ready for production use. [It is used in several projects by Docker, Google, The Linux Foundation, VMWare, Shopify, etc](https://github.com/imdario/mergo#mergo-in-the-wild).
### Important note
Please keep in mind that a problematic PR broke [0.3.9](//github.com/imdario/mergo/releases/tag/0.3.9). I reverted it in [0.3.10](//github.com/imdario/mergo/releases/tag/0.3.10), and I consider it stable but not bug-free. Also, this version adds suppot for go modules.
Keep in mind that in [0.3.2](//github.com/imdario/mergo/releases/tag/0.3.2), Mergo changed `Merge()`and `Map()` signatures to support [transformers](#transformers). I added an optional/variadic argument so that it won't break the existing code.
If you were using Mergo before April 6th, 2015, please check your project works as intended after updating your local copy with ```go get -u github.com/imdario/mergo```. I apologize for any issue caused by its previous behavior and any future bug that Mergo could cause in existing projects after the change (release 0.2.0).

## Install
go get github.com/imdario/mergo
// use in your .go code
import (
"github.com/imdario/mergo"
)
## Usage
You can only merge same-type structs with exported fields initialized as zero value of their type and same-types maps. Mergo won't merge unexported (private) fields but will do recursively any exported one. It won't merge empty structs value as [they are zero values](https://golang.org/ref/spec#The_zero_value) too. Also, maps will be merged recursively except for structs inside maps (because they are not addressable using Go reflection).
```go
if err := mergo.Merge(&dst, src); err != nil {
// ...
}
```
Also, you can merge overwriting values using the transformer `WithOverride`.
```go
if err := mergo.Merge(&dst, src, mergo.WithOverride); err != nil {
// ...
}
```
Additionally, you can map a `map[string]interface{}` to a struct (and otherwise, from struct to map), following the same restrictions as in `Merge()`. Keys are capitalized to find each corresponding exported field.
```go
if err := mergo.Map(&dst, srcMap); err != nil {
// ...
}
```
Warning: if you map a struct to map, it won't do it recursively. Don't expect Mergo to map struct members of your struct as `map[string]interface{}`. They will be just assigned as values.
Here is a nice example:
```go
package main
import (
"fmt"
"github.com/imdario/mergo"
)
type Foo struct {
A string
B int64
}
func main() {
src := Foo{
A: "one",
B: 2,
}
dest := Foo{
A: "two",
}
mergo.Merge(&dest, src)
fmt.Println(dest)
// Will print
// {two 2}
}
```
Note: if test are failing due missing package, please execute:
go get gopkg.in/yaml.v2
### Transformers
Transformers allow to merge specific types differently than in the default behavior. In other words, now you can customize how some types are merged. For example, `time.Time` is a struct; it doesn't have zero value but IsZero can return true because it has fields with zero value. How can we merge a non-zero `time.Time`?
```go
package main
import (
"fmt"
"github.com/imdario/mergo"
"reflect"
"time"
)
type timeTransformer struct {
}
func (t timeTransformer) Transformer(typ reflect.Type) func(dst, src reflect.Value) error {
if typ == reflect.TypeOf(time.Time{}) {
return func(dst, src reflect.Value) error {
if dst.CanSet() {
isZero := dst.MethodByName("IsZero")
result := isZero.Call([]reflect.Value{})
if result[0].Bool() {
dst.Set(src)
}
}
return nil
}
}
return nil
}
type Snapshot struct {
Time time.Time
// ...
}
func main() {
src := Snapshot{time.Now()}
dest := Snapshot{}
mergo.Merge(&dest, src, mergo.WithTransformers(timeTransformer{}))
fmt.Println(dest)
// Will print
// { 2018-01-12 01:15:00 +0000 UTC m=+0.000000001 }
}
```
