Necessary additional files from version adhoc 20101111
******************************************************
FreeAdhocUDF uses from version adhoc 20101111 own compiled, current ICU-libs (Version 4.4.2) for using with UTF-8.
To avoid conflicts with the (reduced) ICU-libs from FireBird (version 3.0), we have signed our libs with the extention FAU - and dynamic linking on this files.
For this reason it is necessary from version adhoc 20101111, equal for InterBase or FireBird, to use this icu-files. 
If the system doesn't find this dynamic libs, the database-server sendout following error-message
---------------------------------------------
Invalid token.
invalid request BLR at offset ...
function ... is not defined.
module name or entrypoint could not be found.
---------------------------------------------
on *every* function of FreeAdhocUDF.

Due to OS the icu-files has to be copied and linked to specified locations.

    * for WindowsXP - from InterBase 2009 and FireBird 2.0
          o copy the following files in folder .../bin of the database-server
                + icudt44FAU.dll
                + icuin44FAU.dll
                + icuio44FAU.dll
                + icuuc44FAU.dll
          o install the Microsoft Visual C++ 2008 Redistributable Package. You can download it from here:
                + Microsoft Visual C++ 2008 SP1 Redistributable Package (x86)
                + Microsoft Visual C++ 2008 SP1 Redistributable Package (x64)
    * for Windows Vista and Windows 7 - from InterBase 2009 and FireBird 2.0
          o copy the following files in folder .../bin of the database-server
                + icudt44FAU.dll
                + icuin44FAU.dll
                + icuio44FAU.dll
                + icuuc44FAU.dll
    * for Linux - from InterBase2009 and FireBird 2.0
          o copy the following files on folder .../lib of the database-server
                + libicudataFAU.so.44.2
                + libicui18nFAU.so.44.2
                + libicuioFAU.so.44.2
                + libicuucFAU.so.44.2
          o check the path of the other from FreeAdhocUDF used libraries, simply run in folder ../UDF
                + ldd FreeAdhocUDF.so
                      # where is the location of libib_util.so?
                            * i.e..: in /usr/lib
          o linking to the same folder than the libib_util.so following symbolic links
            (look at the cript create_icu-symlinks_for_using.sh)
            example for Firebird in folder /opt/firebird and libib_util.so in folder /usr/lib:
                + ln -s /opt/firebird/lib/libicudataFAU.so.44.2 /usr/lib/libicudataFAU.so.44
                + ln -s /opt/firebird/lib/libicui18nFAU.so.44.2 /usr/lib/libicui18nFAU.so.44
                + ln -s /opt/firebird/lib/libicuioFAU.so.44.2 /usr/lib/libicuioFAU.so.44
                + ln -s /opt/firebird/lib/libicuucFAU.so.44.2 /usr/lib/libicuucFAU.so.44
