Also add --script option to turn the option back on.
Previously there wasn't a way to get an interactive IRB session
and access arguments provided on the command line.
Additionally, handle `-` as script as stdin. In Unix-like tools, `-`
means to take standard input instead of a file. This doesn't
result in exactly the same output for:
```
echo 'p ARGV' > args.rb; irb args.rb a b c
```
and
```
echo 'p ARGV' | irb - a b c
```
Due to how irb handles whether stdin is a tty.
However, this change allows use of `-` as a argument, instead of
giving an unrecognized switch error. This required some small
changes to context.rb (to handle `-` as standard input) and
input-method.rb (to have FileInputMethod accept IO arguments in
addition to strings).

The test randomly gets stuck on Solaris:

```
1) Error:
TestIRB::TestInit#test_recovery_sigint:

```
I investigated the issue but I couldn't figure it out.
This random failure is noisy, which makes it difficult to track the CI.
So I skip the test on Soalris. Contribution is welcome.
is not changed.
At first `ARGV.unshift('something')` was suggested for r61149,
but it wasn't sufficient because it modifies $0.
Not only to preserve ARGV, but also r61149 intends to preserve $0.
This test prevents future breakage of the behavior.

This is not perfectly good solution (at least we don't want to have ARGV
as default value of `argv` argument), but unfortunately IRB.setup and
IRB.parse_opts are public methods and we can't make breaking change to
those methods.
We may deprecate using them and then make them private in the future,
but the removal should not be in Ruby 2.5. So I kept their interface for
now.
