While working on another project we noticed that there were no tests for
the cvar overtaken exception when using classes. This change adds a test
for cvar overtaken with classes and moves the cvar overtaken test for
modules into the new file.

It looks like GitHub syntax-highlighting does not support an empty
heredoc. This change adds a newline to make GitHub can handle the syntax
appropriately.

This test was triggering require of `rubygems/core_ext/tcpsocket_init`
which overrides TCPSocket.initialize globally. Requires don't get
reset between test runs and it was making other test unreliable.

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.

This lets us cast a Fiddle::Function to a block, allowing is to write
things like:
```ruby
f = Fiddle::Function.new(@libc['strcpy'], [TYPE_VOIDP, TYPE_VOIDP], TYPE_VOIDP)
define_method :strcpy, &f
```
It's important to only make the origin when the prepend goes
through, as the precense of the origin informs whether to do an
origin backfill.
This plus 2d877327e fix [Bug #17590].
With this patch, TracePoint receives a `:fiber_switch` event for
_almost_ every fiber switch. Previously, it would not be sent when an
exception was going to be raised. Now the event should only be blockable
by an interrupt (including `Thread#raise`) or a fatal error.
Additionally, interrupts will now be checked on the return fiber
_before_ re-raising the terminating unhandled exception. And a fiber
that terminates with an unhandled exception no longer creates a pending
interrupt on its thread. The exception will be raised in the return
fiber the same way as `Fiber#raise`: using `cont.value` with `cont.argc
== -1`
I moved `rb_exc_raise` from `fiber_store` to the end of `fiber_switch`
after _all_ of the other cleanup code: `fiber_stack_release`,
`th->blocking` increment, `RUBY_VM_CHECK_INTS`, and `EXEC_EVENT_HOOK`.
It seems to me that skipping those other cleanup steps may have also
resulted in other bugs.
The documentation already specifies that they strip whitespace
and defines whitespace to include null.
This wraps the new behavior in the appropriate guards in the specs,
but does not specify behavior for previous versions, because this
is a bug that could be backported.
Fixes [Bug #17467]
Previously, frames with iseq but no pc were skipped (even before
the refactoring in 3b24b7914c).
Because the entire backtrace was procesed before the refactoring,
this was handled by using later frames instead. However, after
the refactoring, we need to handle those frames or they get
lost.
Keep two iteration counters when iterating, one for the desired
backtrace size (so we generate the desired number of frames), and
one for the actual backtrace size (so we don't process off the end
of the stack). When skipping over an iseq frame with no pc,
decrement the counter for the desired backtrace, so it will
continue to process the expected number of backtrace frames.
Fixes [Bug #17581]
negative cache on a class which does not have subclasses was not
invalidated, but it should be invalidated because other classes
can cache this negative cache.
[Bug #17553]
Check for cyclic prepend before making any changes. This requires
scanning the module ancestor chain twice, but in general modules
do not have large numbers of ancestors.
* Rename `rb_scheduler` to `rb_fiber_scheduler`.
* Use public interface if available.
* Use `rb_check_funcall` where possible.
* Don't use `unblock` unless the fiber was non-blocking.
