The tracked generated files (configure, */Makefile.in, ltmain.sh, aux
scripts) had drifted stale: src/Makefile.in predated #343, which added
htscache_selftest.c to the library sources, so a plain
`bash configure && make` link-failed with "undefined reference to
cache_selftests". CI regenerates with `autoreconf -fi` on every run, so it
never saw the staleness.
Regenerate with `autoreconf -fi` so a from-checkout build needs no autotools
installed, as intended. This also bumps the generators (autoconf 2.71->2.72,
automake 1.17, libtool 2.4.7), hence the large but purely generated diff.
Also commit the automake test-driver aux script (its siblings compile,
depcomp, missing, install-sh are already committed); without it `make check`
on a fresh checkout could not find $(top_srcdir)/test-driver. A clean
checkout now builds and passes `make check` with no autotools installed.
