    Add TODO for crc_table

    crc_table is also in JZlib. We don't want to have it by ourselves.

    Update tags for new zlib implementation

     * Add mtime tag for 1.9 as well as 1.8
     * Remove tags which now get green with new zlib

commit 21eaa91
Author: Hiroshi Nakamura <[email protected]>
Date:   Tue Oct 4 14:51:53 2011 +0900

    Prepare for merging new zlib impl by ymnk

     * Remove unused implementation for Inflate, Deflate, GzipReader and
       GzipWriter (all replaced by ymnk with helps from JZlib)

     * Remove duplicated constant definitions in Zlib.java

     * Move RaiseException helper methods from Util.java to RubyZlib.java
       (We can remove Util.java now)

     * Fix a bug to avoid IndexOutOfBoundException raised from
       GzipWriter#write when the argument is empty String.

     * Tag 1 RubySpec failure which expects following code to fail with
       'header already written'. It's JZlib's incompatibility but I (NaHi)
       don't think it's a 'bug' of JZlib.
         Zlib::GzipWriter.wrap(StringIO.new) { |io| io.write("a"); io.mtime = nil }

     * Update Eclipse classpath setting

    Re-implement Zlib::GzipReader and Zlib::GzipWriter with jzlib.

      * using JZlib 1.1.0
        build_lib/jzlib-1.1.0.jar is built from
        https://github.com/ymnk/jzlib/tree/1.1.0

      * working around JRUBY-6073 (61633af)

      * GzipReader will throw appropieate exceptions for broken input. (1cd2f52)
        * NoFooter if not enough trailer data exits,
        * CRCError if incorrect checksum data is found,
        * LengthError if incorrect length data is found,
        * GzipFile::Error if header is broken or EOF is countered before trailer,
        * DataError if invalid compression data is found.
        * Note that the previous JRuby had thrown IOError instead of DataError.

      * Fix 'Zlib::Inflate#<< properly handles incomplete data ERROR' on RubySpec. (710dbba)

      * Support Zlib::File:Error#input (41eff81)
        * Since Ruby 1.9, Zlib::File:Error#input has been introduced.
          According to the source code of CRuby, it will be setted at the failure
          in parsing the gzip header.

      * Support some methods additionaly (90dc869)
        * GzipReader#unused,
        * GzipWriter#sync, GzipWriter#sync=
        * GzipWriter#flush
