* Prefix with "_libdeflate_" all global symbols which are not part of the API.
* This avoids exposing overly generic names when libdeflate is built as a
* static library.
*
* Note that the chosen prefix is not really important and can be changed
* without breaking library users. It was just chosen so that the resulting
* symbol names are unlikely to conflict with those from any other software.
* Also note that this fixup has no useful effect when libdeflate is built as a
* shared library, since these symbols are not exported.
