I used the C api here, but verified that the behavior was the same
as using the C++ getBaseName API.
927fee5656/src/features/icu.cpp (L249-L268)
I tried to keep the implementation naming at least similar to the
work in: https://phabricator.services.mozilla.com/D118070
However, the implementation do diverge. I figure in the future, the
APIs can be made similar, but at least the gtests will ensure the
behavior remains the same.
