p2p: make Switch.DialSeeds use a new PRNG per call 
Fixes https://github.com/tendermint/tendermint/issues/875

Ensure that every DialSeeds call uses a new PRNG seeded from
tendermint/tmlibs/common.RandInt which internally uses
crypto/rand to seed its source.

p2p: use bytes.Equal for key comparison 
Updates https://github.com/tendermint/tendermint/issues/850

My security alarms falsely blarred when I skimmed and noticed
keys being compared with `==`, without the proper context
so I mistakenly filed an issue, yet the purpose of that
comparison was to check if the local ephemeral public key
was just the least, sorted lexicographically.

Anyways, let's use the proper bytes.Equal check, to save future labor.

p2p: netPipe for <Go1.10 in own file with own build tag 
Follow up of 283544c7f3
putting <Go1.10 implementation of netPipe in its own
file and protect it with its separate build tag.

p2p: use fake net.Pipe since only >=Go1.10 implements SetDeadline 
Fixes https://github.com/tendermint/tendermint/issues/851

Go1.9 and below's net.Pipe did not implement the SetDeadline
method so after commit
e2dd8ca946
this problem was exposed since now we check for errors.

To counter this problem, implement a simple composition for
net.Conn that always returns nil on SetDeadline instead of
tripping out.

Added build tags so that anyone using go1.10 when it is released
will be able to automatically use net.Pipe's net.Conns

p2p: peer should respect errors from SetDeadline

p2p: peer should respect errors from SetDeadline 
Noticed while auditing the code that we aren't respecting
(*net.Conn) SetDeadline errors which return after
a connection has been killed and is simultaneously
being used.

For example given program, without SetDeadline error checks
```go
package main

import (
  "log"
  "net"
  "time"
)

func main() {
  conn, err := net.Dial("tcp", "tendermint.com:443")
  if err != nil {
    log.Fatal(err)
  }
  go func() {
    <-time.After(400 * time.Millisecond)
    conn.Close()
  }()
  for i := 0; i < 5; i++ {
    if err := conn.SetDeadline(time.Now().Add(time.Duration(10 * time.Second))); err != nil {
      log.Fatalf("set deadline #%d, err: %v", i, err)
    }
    log.Printf("Successfully set deadline #%d", i)
    <-time.After(150 * time.Millisecond)
  }
}
```

erraneously gives
```shell
2017/11/14 17:46:28 Successfully set deadline #0
2017/11/14 17:46:29 Successfully set deadline #1
2017/11/14 17:46:29 Successfully set deadline #2
2017/11/14 17:46:29 Successfully set deadline #3
2017/11/14 17:46:29 Successfully set deadline #4
```

However, if we properly fix it to respect that error with
```diff

p2p: comment on the wg.Add before go saveRoutine() 
Just noticed while auditing the code in p2p/addrbook.go,
wg.Add(1) but no subsequent defer.
@jaekwon and I had a discussion offline and we agreed to
comment about why the code was that way and why
we shouldn't move the wg.Add(1) into .saveRoutine() because
if go a.saveRoutine() isn't started before anyone invokes
a.Wait(), then we'd have raced a.saveRoutine().
