* Add a "pinning" reference
A `Fiddle::Pinned` objects will prevent the objects they point to from
moving. This is useful in the case where you need to pass a reference
to a C extension that keeps the address in a global and needs the
address to be stable.
For example:
```ruby
class Foo
A = "hi" # this is an embedded string
some_c_function A # A might move!
end
```
If `A` moves, then the underlying string buffer may also move.
`Fiddle::Pinned` will prevent the object from moving:
```ruby
class Foo
A = "hi" # this is an embedded string
A_pinner = Fiddle::Pinned.new(A) # :nodoc:
some_c_function A # A can't move because of `Fiddle::Pinned`
end
```
This is a similar strategy to what Graal uses:

* rename global to match exception name
* Introduce generic Fiddle::Error and rearrange error classes
Fiddle::Error is the generic exception base class for Fiddle exceptions.
This commit introduces the class and rearranges Fiddle exceptions to
inherit from it.

Ruby 2.7 deprecates taint and it no longer has an effect.
The lack of taint support should not cause a problem in
previous Ruby versions.
