Backport lib/reline, and lib/irb for 3.0.1 4th (#4349) 
* [ruby/irb] Update help message for next context-mode of 4

While here, fixing tab/space issues in help message, and sync
rdoc for IRB class to match the help message.

ef8e3901cc

* [ruby/irb] Do not continue line if last expression is an endless range

Fixes [Bug #14824]

63414f8465

* [ruby/irb] Add a test for not continuing when endless range at eol

1020ac9c65

* [ruby/irb] Make save-history extension safe for concurrent use

This makes the save-history extension check for modifications to
the history file before saving it.  If the history file was modified
after the history was loaded and before it was saved, append only
the new history lines to the history file.

This can result in more lines in the history file than SAVE_HISTORY
allows.  However, that will be fixed the next time irb is run and
the history is saved.

Fixes [Bug #13654]

* Fix errors when XDG_CONFIG_HOME points to non-writable directory

`$HOME/.config` is not writable on CI
because I think tests should not corrupt user's data.

And GitHub Actions CI sets `XDG_CONFIG_HOME`
since `Version: 20210309.1`.

https://github.com/ruby/actions/runs/2130811016?check_suite_focus=true#step:16:301
```
Errno::EACCES: Permission denied @ dir_s_mkdir - /home/runner/.config/irb
```

* Try to fix errors in TestIRB::TestHistory too

* [ruby/irb] Always add input method when calling Irb.new in tests

When passes input method as nil to Context.new through Irb.new,
ReidlineInputMethod.new is executed and the global internal state of Reline is
rewritten, therefore other tests are failed in the Ruby repository. This
commit changes to use TestInputMethod.

010dce9210

* [ruby/irb] Prevent the completion from crashing if rdoc is missing

There are cases where ruby is installed without rdoc and e.g.
lib/irb/cmd/help.rb also handles the LoadError

Here is how to replicate the issue:

```
$ docker run -it alpine:3.13.3 sh

/ # apk add ruby ruby-irb ruby-io-console

/ # irb

irb(main):001:0> Class[TAB][TAB]
```

And you end up with something like:

```

* [ruby/irb] Suppress verbose messages in the parallel test

`:VERBOSE` flag needs to be set prior to `IRB::Irb.new`.

78604682d9

* [ruby/irb] SIGINT should raise Interrupt after IRB session

5832cfe75b

* [ruby/irb] Colorize `__END__` as keyword

9b84018311

* [ruby/irb] Add show_source command

108cb04352

* [ruby/reline] Reset @rest_height when clear screen

3a7019b0d5

* [ruby/irb] process multi-line pastes as a single entity

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>
```
