Wu, Chia-I (吳佳一) a0911343ee Major update to distinguish between unsorted and overlapped segments 
for cmap format 4.  For overlapped but sorted segments, which is
previously considered unsorted, we still use binary search.

* src/sfnt/ttcmap.h (struct  TT_CMapRec_): Replace `unsorted' by
`flags'.
(TT_CMAP_FLAG_UNSORTED, TT_CMAP_FLAG_OVERLAPPED): New macros.

* src/sfnt/ttcmap.c (OPT_CMAP4): Removed as it is always defined.
(struct TT_CMap4Rec_): Remove `old_charcode' and `table_length'.
(tt_cmap4_reset): Removed.
(tt_cmap4_init): Updated accordingly.
(tt_cmap4_next): Updated accordingly.
Take care of overlapped segments.
(tt_cmap4_validate): Make sure the subtable is large enough.
Do not check glyph_ids because some fonts set the length wrongly.
Also, when all segments have offset 0, glyph_ids is always invalid. It
does not cause any problem so far only because the check misses
equality.
Distinguish between unsorted and overlapped segments.
(tt_cmap4_char_map_linear, tt_cmap4_char_map_binary): New functions to
do "charcode => glyph index" by linear/binary search.
(tt_cmap4_char_index, tt_cmap4_char_next): Use
tt_cmap4_char_map_linear and tt_cmap4_char_map_binary.
(tt_face_build_cmaps): Treat the return value of validator as flags
for cmap.

README 

  Special notes to Unix users
  ===========================

  Please  read  the file  "docs/UPGRADE.UNX".   It contains  important
  information regarding the installation  of FreeType on Unix systems,
  especially GNU based operating systems like GNU/Linux.

  FreeType 2's  library is called `libfreetype',  FreeType 1's library
  is called `libttf'.  They are *not* compatible!


  FreeType 2.1.10
  ===============

  Please read the docs/CHANGES file, it contains IMPORTANT INFORMATION.

  Read the files "docs/INSTALL" for installation instructions.

  Note  that  the FreeType  2  documentation  is  now available  as  a
  separate package from our sites.  See:

    ftp://ftp.freetype.org/freetype/freetype2/ftdocs-2.1.10.tar.bz2
    ftp://ftp.freetype.org/freetype/freetype2/ftdocs-2.1.10.tar.gz
    ftp://ftp.freetype.org/freetype/freetype2/ftdoc2110.zip


  Bugs
  ====

  Please report bugs by  e-mail to `devel@freetype.org'.  Don't forget
  to send  a detailed explanation of  the problem --  there is nothing
  worse  than receiving  a terse  message that  only says  "it doesn't
  work".


  Enjoy!
