 * Prefix with "_libdeflate_" all global symbols which are not part of the API
 * and don't already have a "libdeflate" prefix.  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.
