This reverts commit f3a5b2b22f875a08c4d1253a866327c4551f0d73. That commit reverted 3afafdb6cda45b8879aa284d5fb90c3446584bfc. The reason was one of the removed deprecated functions being present in mathoms had an extra purpose, making sure that the functions in mathoms.c get loaded. The commit just prior to this one created a different mechanism for forcing that load, so the the reason for the original revert is gone, so it can be reapplied.
