[Tarantool-patches] [PATCH] Add missed icu symbols

[Alexandr Barulev]

Hello, thank you for the review!

I took into account the comments and soon i will send new version
of the patch.

About additional macroses like EXPORT_ICU and others, as Timur
mentioned, seems there is no need to create them, because as I
noted in commentary at src/exports_icu.h - unicode/urename.h
file do this work (maps exported symbols to symbols with version
suffix, if library is build with option --enable-renaming). Also we
can't rely on U_ICU_ENTRY_POINT_RENAME macros, because old versions
of libicu don't contain this macros and unicode/urename.h has a
simple symbols mapping:
#define symbol symbol_suffix
So, I think, include <unicode/urename.h> is enough.

Regards,
Alexandr
