* ext/openssl/ossl_ssl.c (ossl_start_ssl): should wait for that

  the underlying IO become readable or writable if the error was
  SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE. [ruby-dev:25795]

* ext/openssl/ossl_ssl.c (ossl_ssl_read, ossl_ssl_write): ditto.

* ext/openssl/lib/openssl/buffering.rb
  (Buffering#consume_rbuf): pointless eof flag resetting is deleted.
  (Buffering#read): should return an empty string if the specified
  size is zero.
  (Buffering#readpartial): new method.
  (Buffering#readline): fix typo.
  (Buffering#getc): return the first character of string correctly.
  (Buffering#readchar): fix typo.
  (Buffering#eof?): should read again it the input buffer is empty.
  (Buffering#do_write): should rescue Errno::EAGAIN.
  (Buffering#puts): use "\n" as the output field separator.

* ext/openssl/extconf.rb: get rid of GNUmakefile generation.

* text/openssl/test_pair.rb: test for IO like methods.

* test/ruby/ut_eof.rb: test about empty file.
