* test/Makefile.in (srcdir, top_srcdir): Use @srcdir@, etc. (top_builddir, abs_srcdir, abs_top_builddir, abs_top_srcdir): Likewise. (so_name): Remove definition. (.bin-dir-stamp): No longer create symlink in $(DMDIR) tree. Prompted by suggestions from Alasdair Kergon. * test/t1000-lvcreate-usage.sh (cleanup_): Redirect to a file, rather than to /dev/null. Change wording of some test titles. Suggestions from Alasdair Kergon. * test/Makefile.in: Add a copyright notice. * test/lvm-utils.sh: Likewise. * test/mkdtemp: Likewise. * test/t0000-basic.sh: Likewise. * test/t1000-lvcreate-usage.sh: Likewise. * test/t3000-lvcreate-pvtags.sh: Likewise. * test/t4000-pv-range-overflow.sh: Likewise. * test/test-lib.sh: Likewise.
