values
(https://github.com/ruby/irb/pull/953)
Currently, users can only find out that they have set a wrong value
for IRB configs when the value is used, with opaque error messages like
"comparison of Integer with true failed (TypeError)".
This commit adds a new initialization step to validate the values of
some IRB configs, so that users can find out about the wrong values
during the initialization of IRB.

The test assumes `:foo` is a static symbol, but that is only true
if a literal `:foo` was parsed before `"foo".to_sym` was evaled:
```ruby
require 'objspace'
foo_sym = "foo".to_sym
puts ObjectSpace.dump(eval(":foo"))
```
```
{"address":"0x100fb46d0", "type":"SYMBOL", "shape_id":10, "slot_size":40, "class":"0x100d3e9c8", "frozen":true, "bytesize":3, "value":"foo", "memsize":40, "flags":{"wb_protected":true, "marking":true, "marked":true}}

commands
(https://github.com/ruby/irb/pull/944)
* Avoid raising errors while running help for custom commands
Raising an error from the help command is not a pleasure for the
end user, even if the command does not define any attributes
* Update test/irb/command/test_custom_command.rb

This gets in the middle if we ever start allowing to build as if using a
different RubyGems version than the one being run.
This could be useful to make `gem rebuild` a little more usable, and
it's already done by Bundler specs which already make this method a noop
when they need this.
I'm not sure forcefully setting this, even if user explicitly specified
something else is helpful.
Since this could potentially prevent gems explicitly setting a constant
RubyGems version from building, I changed the error of incorrect
RubyGems version from a hard error to a warning, since it will start
happening in those cases if we stop overwriting the version.

This has been requested for a long time, and I'm finally doing it
now. Unfortunately this is a breaking change for all of the APIs.
I've added in a Ruby method for `#child` that is deprecated so that
existing usage doesn't break, but for everyone else this is going
to be a bit of a pain.
