* ext/zlib/zlib.c: Added streaming support to inflate processing.

  This allows zlib streams to be processed without huge memory growth.
  [Feature #6612]
* NEWS:  ditto
* ext/zlib/zlib.c (zstream_expand_buffer):  Uses rb_yield when a block
  is given for streaming support.  Refactored to use
  zstream_expand_buffer_into to remove duplicate code.
* ext/zlib/zlib.c (zstream_expand_buffer_protect):  Added wrapper
  function to pass jump state back through GVL-free section to allow
  zstream clean-up before terminating the ruby call.
* ext/zlib/zlib.c (zstream_expand_buffer_without_gvl):  Acquire GVL to
  yield processed chunk of output stream.
* ext/zlib/zlib.c (zstream_detach_buffer):  When a block is given,
  returns Qnil mid-stream and yields the output buffer at the end of
  the stream.
* ext/zlib/extconf.rb:  Update INCFLAGS to find internal.h for
  rb_thread_call_with_gvl
* test/zlib/test_zlib.rb:  Updated tests
