server: terminal width should fallback to 80x25. (#1895) 

Some environments might disable access to `/dev/tty`, fall
back to '80' in such scenarios.

Move to 'cheggaaa/pb' package for better cross platform
support on fetching terminal width.

Fixes #1891

# Terminal progress bar for Go
Simple progress bar for console programs.
## Installation
```
go get gopkg.in/cheggaaa/pb.v1
```
## Usage
```Go
package main
import (
"gopkg.in/cheggaaa/pb.v1"
"time"
)
func main() {
count := 100000
bar := pb.StartNew(count)
for i := 0; i < count; i++ {
bar.Increment()
time.Sleep(time.Millisecond)
}
bar.FinishPrint("The End!")
}
```
Result will be like this:
```
> go run test.go
37158 / 100000 [================>_______________________________] 37.16% 1m11s
```
## Customization
```Go
// create bar
bar := pb.New(count)
// refresh info every second (default 200ms)
bar.SetRefreshRate(time.Second)
// show percents (by default already true)
bar.ShowPercent = true
// show bar (by default already true)
bar.ShowBar = true
// no counters
bar.ShowCounters = false
// show "time left"
bar.ShowTimeLeft = true
// show average speed
bar.ShowSpeed = true
// sets the width of the progress bar
bar.SetWidth(80)
// sets the width of the progress bar, but if terminal size smaller will be ignored
bar.SetMaxWidth(80)
// convert output to readable format (like KB, MB)
bar.SetUnits(pb.U_BYTES)
// and start
bar.Start()
```
## Progress bar for IO Operations
```go
// create and start bar
bar := pb.New(myDataLen).SetUnits(pb.U_BYTES)
bar.Start()
// my io.Reader
r := myReader
// my io.Writer
w := myWriter
// create proxy reader
reader := bar.NewProxyReader(r)
// and copy from pb reader
io.Copy(w, reader)
```
```go
// create and start bar
bar := pb.New(myDataLen).SetUnits(pb.U_BYTES)
bar.Start()
// my io.Reader
r := myReader
// my io.Writer
w := myWriter
// create multi writer
writer := io.MultiWriter(w, bar)
// and copy
io.Copy(writer, r)
bar.Finish()
```
## Custom Progress Bar Look-and-feel
```go
bar.Format("<.- >")
```
## Multiple Progress Bars (experimental and unstable)
Do not print to terminal while pool is active.
```go
package main
import (
"math/rand"
"sync"
"time"
"gopkg.in/cheggaaa/pb.v1"
)
func main() {
// create bars
first := pb.New(200).Prefix("First ")
second := pb.New(200).Prefix("Second ")
third := pb.New(200).Prefix("Third ")
// start pool
pool, err := pb.StartPool(first, second, third)
if err != nil {
panic(err)
}
// update bars
wg := new(sync.WaitGroup)
for _, bar := range []*pb.ProgressBar{first, second, third} {
wg.Add(1)
go func(cb *pb.ProgressBar) {
for n := 0; n < 200; n++ {
cb.Increment()
time.Sleep(time.Millisecond * time.Duration(rand.Intn(100)))
}
cb.Finish()
wg.Done()
}(bar)
}
wg.Wait()
// close pool
pool.Stop()
}
```
The result will be as follows:
```
$ go run example/multiple.go
First 141 / 1000 [===============>---------------------------------------] 14.10 % 44s
Second 139 / 1000 [==============>---------------------------------------] 13.90 % 44s
Third 152 / 1000 [================>--------------------------------------] 15.20 % 40s
```

ts (Terminal Size)
==
[![Build Status](https://travis-ci.org/olekukonko/ts.png?branch=master)](https://travis-ci.org/olekukonko/ts) [![Total views](https://sourcegraph.com/api/repos/github.com/olekukonko/ts/counters/views.png)](https://sourcegraph.com/github.com/olekukonko/ts)
Simple go Application to get Terminal Size. So Many Implementations do not support windows but `ts` has full windows support.
Run `go get github.com/olekukonko/ts` to download and install
#### Example
```go
package main
import (
"fmt"
"github.com/olekukonko/ts"
)
func main() {
size, _ := ts.GetSize()
fmt.Println(size.Col()) // Get Width
fmt.Println(size.Row()) // Get Height
fmt.Println(size.PosX()) // Get X position
fmt.Println(size.PosY()) // Get Y position
}
```
