* transcode_data.h (rb_transcoding): add fields for restartable
transcoding. (rb_transcoder): add max_input field. from_unit_length field is renamed to input_unit_length. * tool/transcode-tblgen.rb: generate max_input field. * enc/trans/iso2022.erb.c: follow rb_transcoder change. * enc/trans/utf_16_32.erb.c: ditto. * transcode.c (PARTIAL_INPUT): new constant. (transcode_char_start): new function. (transcode_result_t): new type. (transcode_restartable): new function. (more_output_buffer): new function. (transcode_loop): use transcode_restartable. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@18452 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
