* Document Fiber's method related to scheduling;
* Extend Fiber's class docs with concepts of non-blocking
fibers;
* Introduce "imaginary" (documentation-only) class
Fiber::SchedulerInterface to properly document how
scheduler's methods should look.
Pointed out by @shyouhei.
NOTE: Already we have dropped the support for older MSVCs,
probably prior to 1300 or 1400. Remove the conditional code,
especially in win32/Makefile.sub.

"experimental_everything" makes the assigned value, it means
the assignment change the state of assigned value.
"experimental_copy" tries to make a deep copy and make copyied object
sharable.
Previously, due to a change to fix bug 15608, Method#inspect output
changed for class methods:
Ruby 2.7
"#<Method: String.prepend(*)>"
Before change:
"#<Method: #<Class:Object>(Module)#prepend(*)>"
This is wrong because the Method object was created from String and
not Object. This is because the fix for bug 15608 assumed it was
being called on the singleton class of a instance, and would skip
the first singleton class until it got to the class itself. For
class methods, this results in always using the superclass. Fix
behavior to not skip until the superclass if the singleton class
is the singleton class of a module or class.
After change:
"#<Method: #<Class:Object>(Module)#prepend(*)>"
Fixes [Bug #17428]
