zlib: GzipReader#rewind preserves ZSTREAM_FLAG_GZFILE
* ext/zlib/zlib.c (gzfile_reset): preserve ZSTREAM_FLAG_GZFILE [Bug #10101] * test/zlib/test_zlib.rb (test_rewind): test each_byte We must preserve the ZSTREAM_FLAG_GZFILE flag to prevent zstream_detach_buffer from: a) returning Qnil and breaking out of the `each_byte' loop b) yielding a large string to each_byte Note: the test case in bug report takes a long time. I found this bug because I noticed the massive time descrepancy between `each_byte' and `readbyte' loop before this patch. With this patch, `each_byte' and `readbyte' both take very long. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@47327 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
