Subject: [PATCH 1/5] More explicit require
This class does not use `rubygems/deprecate`. It uses
`rubygems/version`, which in turn uses `rubygems/deprecate`. Make this
explicit.

Subject: [PATCH 3/5] Load `operating_system.rb` customizations before setting
up default gems
It's very common for packagers to configure gem paths in this file, for
example, `Gem.default_dir`. Also, setting up default gems requires these
paths to be set, so that we know which default gems need to be setup.
If we setup default gems before loading `operatin_system.rb`
customizations, the wrong default gems will be setup.
Unfortunately, default gems loaded by `operating_system.rb` can't be
upgraded if we do this, but it seems much of a smaller issue. I wasn't
even fully sure it was the right thing to do when I added that, and it
was not the culprit of the end user issue that led to making that
change.

Subject: [PATCH 5/5] Resolve symlinks in LOAD_PATH when activating
pre-required default gems
Some double load issues were reported a while ago by OS packagers where
if a gem has been required before rubygems, and then after, rubygems
require would cause a double load.
We avoid this issue by activating the corresponding gem if we detect
that a file in the default LOAD_PATH that belongs to a default gem has
already been required when rubygems registers default gems.
However, the fix does not take into account that the default LOAD_PATH
could potentially include symlinks. This change fixes the same double
load issue described above but for situations where the default
LOAD_PATH includes symlinks.
