Yes, it's optional.  The --disable-renaming configure option can be used 
to turn this feature off.  This feature is used so that multiple 
versions of ICU can be used within the same application. This can be 
important when you want to have multiple collation versions, or in a 
huge application where part of it uses the current ICU while the rest 
(maybe from third party vendors) can continue to use older versions of ICU.

This magic is done with a perl script called 
icu/source/tools/genren/genren.pl, which uses nm on Linux.  It's run 
before every release of ICU, and the resulting urename.h is checked in.
