this allows pasting leading-dot chained methods correctly:
```ruby
class A
def a; self; end
def b; true; end
end
a = A.new
a
.a
.b
```
will properly return `true` instead of erroring on the `.a` line:
```
irb(main):001:1* class A
irb(main):002:1* def a; self; end
irb(main):003:0> end
irb(main):004:0*
irb(main):005:0> a = A.new
irb(main):006:0*
irb(main):007:0> a
irb(main):008:0> .a
irb(main):009:0> .a
=> #<A:0x00007f984211fbe8>
```

Omit the results evaluated at assignment if they are too long.
The behavior of ECHO_ON_ASSIGNMENT being on by default is hard to understand,
so I change it to off by default. Instead, we turn OMIT_ON_ASSIGNMENT on by
default. The result is displayed on assignment, but it will always be short
and within one line of the screen.

This reverts commit 2b0b19b87c60d2cdb329979acbb96e12a1f940e7.
New IRB parser needs new Ripper what has lex_state too. The new Ripper is
adopted by Ruby 2.5 or later.

"IRB::InputMethod#eof?" requires eof status each user input but
"ReidlineInputMethod#eof?" used "Reline.eof?" what is singleton data.
"ReidlineInputMethod#eof?" is changed to use the result of user input.
Let's say we are in progress to write `"foo"`:
```
irb> "fo
```
at this moment, nothing is wrong.
It would be just a normal way to write `"foo"`.
Prior to this commit, the `fo` part was warned because of
5b64d7ac6e. But I think warning such a
normal input is not valuable for users.
However, we'd like to warn `:@1` or `@@1` which is also a syntax error.
Then this commit switches the syntax highlight based on whether the
input text is finished or not. When it's not finished yet, it does not
warn compile_error.
Reline is a readline stdlib compatible library. It also supports
multiline input. IRB is improved with Reline and supports multiline.
Besides, supports showing documents when completed.

When you change this to true, you may need to add more tests.
