License-Update: copyright year updated 2000 -> 2020
Update the dmalloc.c license md5 for 5.6.5 and regenerate the patches so
they apply without fuzz (a fatal QA error). Regenerate 150-use_DESTDIR.patch
so DESTDIR also covers the install/installdocs targets; the dmalloc utility
was otherwise installed to the host /usr/bin and failed with permission
denied.
