With the introduction of Happy Eyeballs Version 2 to `Socket::tcp`, the following areas have been mainly enhanced:
- How the value specified for `connect_timeout` works
- How Socket.tcp operates with Happy Eyeballs Version 2
A description for the new option `fast_fallback` has been added in https://github.com/ruby/ruby/pull/11813.
The purpose of this change is to exploit `fbuffer_append_char` that is
faster than `fbuffer_append`.
`array_delim` was a buffer that concatenated a single comma with
`array_nl`. However, in the typical use case (`JSON.generate(data)`),
`array_nl` is empty. This means that `array_delim` was a
single-character buffer in many cases.
`fbuffer_append(buffer, array_delim)` used `memcpy` to copy one byte,
which was not so efficient.
Rather, this change uses `fbuffer_append_char(buffer, ',')` and then
`fbuffer_append(buffer, array_nl)` only when `array_nl` is not NULL.
This speeds up `JSON.generate` by about 9% in a benchmark.

... instead of `generate_json`.
Since the object key is already confirmed to be a string, using a
generic dispatch function brings an unnecessary overhead.
This speeds up `JSON.generate` by about 3% in a benchmark.

Dispatching based on Ruby's VALUE structure is more efficient than
simply cascaded "if ... else if ..." checks.
This speeds up `JSON.generate` by about 5% in a benchmark.

It is safe to use `RARRAY_AREF` here because no Ruby code is executed
between `RARRAY_LEN` and `RARRAY_AREF`.
This speeds up `JSON.generate` by about 4% in a benchmark.

When relative load paths option is enabled, the prefix is determined
at the runtime. The only way to get it outside libruby is to use
rbconfig.rb.

Fix GH-145
Rename `lib/fiddle/jruby.rb` to `lib/fiddle/ffi_backend.rb` as a generic
ffi gem API based implementation.
JRuby and TruffleRuby use `lib/fiddle/ffi_backend.rb`.

to `rb_ary_new_from_values`.

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.
