* 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.

* Use 'J' for HANDLE.
* Use 'Q' for QWORD.
* Define template constants.
* Supply zero bytes in `unpackqw` as well as `unpackdw`.
* Use `String#unpack1`.
Since we cannot read the rvalue_overhead out of the RVALUE anyways (since
it is at the end of the slot), it makes more sense to move it out of
the RVALUE.
We need to keep a pointer to the originally allocated environ because
adding more environment variables can cause it to be changed to something
else.
For example:
100.times do |i|
ENV["FOO#{i}"] = "1"
end
Causes Valgrind to report:
312 bytes in 1 blocks are definitely lost in loss record 9 of 13
