Update to 0.9.4.

New in 0.9.4:
* The data tables and line breaking algorithm have been updated to Unicode
  version 6.0.0.
* A new include file unigbrk.h is provided. It declares functions for
  grapheme cluster breaking, that is, determining the boundaries between
  graphemes. See the documentation chapter "Grapheme cluster breaks in \ 
strings"
  for details.
* In the include file unictype.h, constants are defined for the group of
  general categories LC ("Cased Letter").
* In the include file unictype.h, functions for associating canonical
  combining classes with names have been added:
    uc_combining_class_name
    uc_combining_class_long_name
    uc_combining_class_byname
* In the include file unictype.h, functions for the Arabic joining type and
  the Arabic joining group have been added:
    uc_joining_type_name
    uc_joining_type_long_name
    uc_joining_type_byname
    uc_joining_type
    uc_joining_group_name
    uc_joining_group_byname
    uc_joining_group
* In the include file unictype.h, functions for new predefined properties
  have been added:
    uc_is_property_cased
    uc_is_property_case_ignorable
    uc_is_property_changes_when_lowercased
    uc_is_property_changes_when_uppercased
    uc_is_property_changes_when_titlecased
    uc_is_property_changes_when_casefolded
    uc_is_property_changes_when_casemapped
  But it's recommended to use the case mapping functions from unicase.h
  instead.
* In the include file unictype.h, the functions for bidi class, formerly known
  as bidirectional category, have been renamed:
    uc_bidi_category_name   -> uc_bidi_class_name
    uc_bidi_category_byname -> uc_bidi_class_byname
    uc_bidi_category        -> uc_bidi_class
    uc_is_bidi_category     -> uc_is_bidi_class
  The old function names still exist, but are obsolete.
* In the include file unictype.h, functions for returning long names of
  property values have been added:
    uc_general_category_long_name
    uc_bidi_class_long_name
  The functions
    uc_general_category_byname
    uc_bidi_class_byname
  have been extended to recognize long names as well as short names.
* It is now easier to detect the subminor version: The value of the variable
  _libunistring_version and of the macro _LIBUNISTRING_VERSION now includes
  also the subminor version.
* The functions u8_mbtouc and u8_mbtouc_unsafe now handle ill-formed UTF-8
  input in a better way, that is more compliant with W3C recommendations.
* The functions u8_strcoll, u16_strcoll, u32_strcoll now produce results that
  are less dependent on the iconv implementation in use.
* The functions u8_strstr, u16_strstr, u32_strstr now perform in O(n) time
  worst-case, where n is the sum of the lengths of the argument strings.

Log message:
Import libunistring-0.9.3 as textproc/libunistring.

libunistring provides a library that implements Unicode strings (in
three flavours: UTF-8 strings, UTF-16 strings, UTF-32 strings),
together with functions for Unicode charactets (character names,
classifications, properties) and functions for string processing
(formatted output, width, word breaks, line breaks, normalization,
case folding, regular expressions).
