Task-tracking issue for 1.7:

• implement env["rack.input"] support env["rack.input"] #638
• asynchronous http client implement http client for mruby handler #637 totally async http client #651
• set MRB_INT64 on 64-bit system set MRB_INT64 on 64-bit system #639
• raise error when trying to read rack.input already closed raise error when reading from a closed rack input #644
• use fiber for calling #each to read response from rack app
  • http_request should return response progressively using #each progressive response from mruby #645
  • provide #as_str in response object implement InputStream#as_str #649 (changed to #json as part of totally async http client #651)
  • implement fast-path for rack-app directly passing back the response of http_request to core skip mruby layer when sending data obtained using http_request #665
• respect content-length header supplied from rack app send content length when possible #664
• add tests for Pass header to upstream #565 adjust request header handling, add tests #666
• separate timeout for http_request?
  • at the moment, the value is fixed to that defined using proxy.timeout.io
• provide an easy-to-use API to copy the headers passed to http_request, as well as set x-forwarded-for and x-forwarded-proto, via, etc.?
• find a way to handle 399 response returned after async calls support 399 response from mruby handler running async #707
• related bug issues: fix crash in mrb_str_to_str #647 mruby fiber cleanups #648 Convert header name to lowercase in mruby handler #650 simplify by merging the chunked-sending logic on ruby-side to the main loop #658 body#close must be called #680 fix and reduce the risk of GC-arena related leaks #701
