   Central point for static initialization.

10
   In case of "lazy" mode `BrotliXxxLazyStaticInit` is not provided by the

11
   library. Embedder is responsible for providing it. This function should call

12
   `BrotliXxxLazyStaticInitInner` on the first invocation. This function should

13
   not return until execution of `BrotliXxxLazyStaticInitInner` is finished.

14
   In C or before C++11 it is possible to call `BrotliXxxLazyStaticInitInner`

15
   on start-up path and then `BrotliEncoderLazyStaticInit` is could be no-op;

16
   another option is to use available thread execution controls to meet the

17
   requirements. For possible C++11 implementation see static_init_lazy.cc.
