update jbigkit to 2.0.

Changes in version 2.0 (2008-08-30)

Main new features of release 2.0:

  - This release adds a separate lightweight "T.85" version of the
    encoder and decoder library (jbig85.c, jbig85.h). This new T.85
    library is optimized for embedded low-memory applications, such as
    printers and fax machines. It implements only the subset of the
    JBIG standard that is required by the ITU-T T.85 fax profile,
    namely only a single bit plane (P = 1) and no differential layers
    (DL = D = HITOLO = SEQ = ILEAVE = SMID = TPDON = DPON = DPON =
    DPLAST = 0) and some other restrictions (MY = 0, MX < 128).

    The T.85 library requires only three pixel rows of the
    uncompressed image to reside in memory at any time. This 3-line
    buffer has to be allocated by the calling application, therefore
    the T.85 library will not call any heap management functions such
    as malloc() or free() itself.

  - There are also two new example applications pbmtojbg85 and
    jbgtopbm85 included that provide command-line access to the new
    T.85 library. (Note to distribution maintainers: there is probably
    little point in adding pbmtojbg85 and jbgtopbm85 to precompiled
    JBIG-KIT packages for workstation operating systems, as these two
    programs do not really provide the end user much additional
    functionality beyond what pbmtojbg and jbgtopbm already do, which
    use the full library instead.)

Changes to the original full jbig.c library from version 1.6:

  - the arithmetic codec routines are now located in a separate source
    file (they are now used by both the full library jbig.c and the new
    T.85 library jbig85.c, and might also be of use to other applications)

  - arithmetic decoder behaviour slightly changed to enable the
    lookahead needed to handle T.85-style NEWLEN after the final
    stripe

  - added encoder support for adding comment marker segment

  - added encoder option for using SDRST marker instead of SDNORM
    (only useful to make encoder able to generate a wider range
    of test data)

  - added pbmtojbg options -C and -r, which provide command-line
    access to the previous two extensions

  - slightly improved diagnostic output of jbgtopbm option -d

  - non-English translations of error messages are now provided
    in a separate PO file (e.g., for use with GNU gettext),
    jbg_strerror() no longer has a language attribute and the
    JBG_EN, JBG_DE_8859_1, JBG_DE_UTF_8 constants no longer exist

  - jbg_dec_in() return values changed; the least significant bits of
    the error codes now provide more information about what caused the
    error, beyond what the more general error text messages returned by
    jbg_strerror() reveal

  - pbmtojbg has a new option -f as a shortcut for all the options
    needed to make the output comply to the basic ITU-T T.85 fax
    profile

  - jbg_dec_getwidth(), jbg_dec_getheight(), jbg_dec_getsize(), and
    jbg_dec_getsize_merged() return now an unsigned long value
    (was: long), and return 0 (was: -1) if no image is available yet

  - jbgtopbm now outputs image dimensions in header padded to 10
    digits fixed width, for consistency with jbgtopbm85
    to allow for later in-place update of height due to NEWLEN

  - macro JBG_LICENCE can be changed from the default value "GPL" to a
    licence agreement reference code to if the library is used under a
    commercial licence, to clarify under which exact licence the
    library is used in a particular application
