`MagicFile` was introduced around v0.9.6, which was like 14~15 years ago.
It was needed because back then we needed to read a file's magic comment
to determine the encoding of it, and read it with that encoding.
Commit: 3ee79e89
But now we expect files to be encoded in UTF-8 and don't specify encoding
through magic comments anymore, `MagicFile` can be retired.
SHOW_DOC_DIALOG will be called repeatedly whenever the corresponding key
is pressed, but we only need to require rdoc once. So ideally the
require can be put outside of the proc.
And because when rdoc is not available the entire proc will be
nonfunctional, we can stop registering the SHOW_DOC_DIALOG if we failed
to require rdoc.

* Use local_variables for colorize, code_block_open check, nesting_level and assignment_expression check
* Check if expression is an assignment BEFORE evaluating it. evaluate might define new localvars and change result of assignment_expression?
* Add local_variables dependent code test
* pend local variable dependent test on truffleruby
code_block_open is not working on truffleruby
* Always pass context to RubyLex#lex
* Rename local_variable_assign_code generator method name
* Add assignment expression truncate test
* Add Context#local_variables and make generate_local_variables_assign_code more simple
* Update lib/irb/input-method.rb

* Add a comment why assignment expression check should be done before evaluate

Deprecates IDB::ReidlineInputMethod and USE_REIDLINE in favor of
IRB::RelineInputMethod and USE_RELINE. The Input method uses Reline to
read input from the console, so it can be named directly after the
Reline library like other inputs methods are (Readline, Stdio, etc.).

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).
Implements [Feature #15371]

RDoc is implemented as soft dependency in IRB. See how the rdoc is required in
the files. I reverted the commit below.
```
$ grep -ril rdoc lib/
lib/irb/cmd/help.rb
lib/irb/completion.rb
lib/irb/easter-egg.rb
lib/irb/input-method.rb
```

This has been introduced in 026700499d,
but it seems that this is just be mistake, otherwise the later handling
of `LoadError` would not be needed.

When outputting a (possibly truncated) value, IRB will query the
window size. However, if IRB was piped to another process, stdout
will no longer be a TTY and will not support the `winsize` method.
This fix ensure that stdout is a TTY.

I pushed reline#389 for when convert-meta is not turned on in .inputrc.
Alt+D in irb also needs to be set to the keycode for not using convert-meta.

From Reidline to Reline
Update description used in take_corresponding_syntax_to_kw_do and is_the_in_correspond_to_a_for methods

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.
