Log Message:
update to icu-3.0

major changes:

ICU 3.0 includes the latest bug fixes, locale/charset updates, and
performance/build/porting enhancements.
- Collation
  Collation data is in a separate data tree, allowing for easier
  modularization and maintenance.
  getFunctionalEquivalent API allows for better caching and UI support.
- Unicode 4.0.1
  ICU is updated to the latest version of Unicode standard, which had
  significant property changes.
- CLDR 1.1
  Updates to CLDR 1.1, with many updates to locale data, and special
  emphasis on collation data.
- Formatting
  As an aid to migration of traditional C (stdio) and C++ (iostream)
  formatting, the POSIX-like input/output library, icuio, is officially
  supported.
  Significant digits now supported in DecimalFormat, for general use and
  %g support.
- RFC822 time zone format support in DateFormat for compatibility.
- Currency formatting/parsing improvements
  Allows parsing multiple currencies with one formatter, without knowing the
  currency in advance. Much cleaner design allowing extensibility to other
  measurement units in the future.
- Regular expressions (C)
  The regular expressions framework now features a C API, instead of just C++.
- Locales
  Locale canonicalization spec defined and implemented. Provides
  interoperability with POSIX and .NET locale IDs, more RFC 3066 support.
- Layout engine
  Layout engine now supports using different canonically-equivalent Unicode
  forms of the same text: e.g. a + ´ or á. This is especially important for
  non-Latin scripts.
- Build Environment
  ICU can now build its data library much faster on most platforms.
