Fix GH-104
lib/fiddle/jruby.rb is based on
https://github.com/jruby/jruby/blob/master/lib/ruby/stdlib/fiddle/jruby.rb
.
Here are changes for it:
* Move `Fiddle::TYPE_*` to `Fiddle::Types::*`
* Add `Fiddle::Types::VARIADIC`
* Add `Fiddle::Types::CONST_STRING`
* Add `Fiddle::Types::BOOL`
* Add `Fiddle::Types::INT8_T`
* Add `Fiddle::Types::UINT8_T`
* Add `Fiddle::Types::INT16_T`
* Add `Fiddle::Types::UINT16_T`
* Add `Fiddle::Types::INT32_T`
* Add `Fiddle::Types::UINT32_T`
* Add `Fiddle::Types::INT64_T`
* Add `Fiddle::Types::UINT64_T`
* Add more `Fiddle::ALIGN_*` for the above new `Fiddle::Types::*`
* Add more `Fiddle::SIZEOF_*` for the above new `Fiddle::Types::*`
* Add support for specifying type as not only `Fiddle::Types::*` but
also `Symbol` like `:int`
* Add support for variable size arguments in `Fiddle::Function`
* Add `Fiddle::Closure#free`
* Add `Fiddle::Closure#freed?`
* Add `Fiddle::Error` as base the error class
* Add `Fiddle::Pointer#call_free` and stop using `FFI::AutoPointer` in
`Fiddle::Pointer`
* Add support for `Fiddle::Pointer.malloc {}` `Fiddle::Pointer`
* Add support for `Fiddle::Pointer#free=`
* Add `Fiddle::Pointer#freed?`
* Use binary string not C string for `Fiddle::Pointer#[]`
* Add `Fiddle::Handle.sym_defined?`
* Add `Fiddle::Handle#sym_defined?`
* Add `Fiddle::Handle::DEFAULT`
* Add `Fiddle::ClearedReferenceError`
* Add no-op `Fiddle::Pinned`
Some features are still "not implemented". So there are some "omit"s for
JRuby in tests.
It would happen when the gem is already installed to multiple GEM_PATHS.
RubyGems was removing duplicate specs without considering the
potentially different `base_dir`. That was causing the gem to be
misidentified as not already installed, and a nil specification getting
returned from the installer as a result, causing the crash.
Solve it by making sure `Gem::Specification.all` really iterates through
all the different specifications in all GEM_PATHs.

Currently in my code when I want to create a pathname object and create a path at the same time I must use tap
```
path = Pathname.new("/tmp/new").tap(&:mkpath)
```
I think it would be cleaner to be able to chain on the results of these methods instead:
```
path = Pathname.new("/tmp/new").mkpath
```
When I want to create a tmpdir I often want to manipulate it as a pathname. By introducing Pathname.mktmpdir I can get this behavior.
Currently I must:
```ruby
Dir.mktmpdir do |dir|
dir = Pathname(dir)
# ... code
end
```
I would like to be able to instead:
```ruby
Pathname.mktmpdir do |dir|
# ... code
end
```
Now that we've inlined the eden_heap into the size_pool, we should
rename the size_pool to heap. So that Ruby contains multiple heaps, with
different sized objects.
The term heap as a collection of memory pages is more in memory
management nomenclature, whereas size_pool was a name chosen out of
necessity during the development of the Variable Width Allocation
features of Ruby.
The concept of size pools was introduced in order to facilitate
different sized objects (other than the default 40 bytes). They wrapped
the eden heap and the tomb heap, and some related state, and provided a
reasonably simple way of duplicating all related concerns, to provide
multiple pools that all shared the same structure but held different
objects.
Since then various changes have happend in Ruby's memory layout:
* The concept of tomb heaps has been replaced by a global free pages list,
with each page having it's slot size reconfigured at the point when it
is resurrected
* the eden heap has been inlined into the size pool itself, so that now
the size pool directly controls the free_pages list, the sweeping
page, the compaction cursor and the other state that was previously
being managed by the eden heap.
Now that there is no need for a heap wrapper, we should refer to the
collection of pages containing Ruby objects as a heap again rather than
a size pool
To simplify the implementation, this makes Object#singleton_method
call the same method called by Object#method (rb_obj_method), then
check that the returned Method is defined before the superclass of the
object's singleton class. To keep the same error messages, it rescues
exceptions raised by rb_obj_method, and then raises its own exception.
Fixes [Bug #20620]
