Log message:
        Add refcount builtin.
        * modules/load.c (refcount): New builtin.
        (m4modules): Use correct type.
        * doc/m4.texinfo (Refcount): New section.
        * m4/m4private.h (struct m4_module): Add refcount member.
        (m4_module_refcount) [NDEBUG]: Add faster accessor macro.
        * m4/module.c (m4_module_load): Add symbols to table on first
        load by m4, regardless of other libltdl loads of same module.
        (m4_module_refcount): Use new struct member, rather than relying
        on libltdl count which might be inflated by unrelated loads.
        (m4__module_interface): Optimize.
        (m4__module_next, m4__module_find): Avoid assertions that could
        trigger with unrelated libltdl loads.
        (m4__module_open): Track m4 load count.
        (m4__module_exit): Only unload what m4 loaded.
        (module_remove): Track m4 unloads.
        * NEWS: Document new builtin.
