This is logically part of the next commit. But then, the git diff would
show the old file disappear and the new file appear with new content,
which would be hard to review, so it is split. This commit should
contain no changes in the content (hopefully), so can be skipped during
review.

* Supply --enable-valgrind to configure to run tests (make check)
  under valgrind

* Use two classes of suppressions files:
 + src/valgrind-suppressions for permanent suppressions that we
   never want to re-consider again
 + src/valgrind-suppressions.revisit for temporary suppressions
  (such as issues in testcases) that are not a priority to fix,
  but we'd like to fix them sometime

And for check_LTLIBRARIES to noinst_LTLIBRARIES too.

This is so a regular "make" will build the test programs and
libraries too.  So the "make check" will just run the tests (and
not build them).  This is to help with test-driven development.

This reverses some from #1091, plus does the rest too.

Note that doing a "make check" before a "make" does not currently
work due to dependencies depending on each other (e.g. python/isc/log
tests needs datasrc but python/isc/datasrc tests need log_config_update).

and while here also only build when the "make check" target is used;
since we already require --with-gtest maybe this step is not of much
interest.

still need to find a real solution for this problem...

For some reason, libtool is not picking up this library from the
dependency in libutil_unittests.  Adding the library to the link
cures the problem.

Also, move the directory util/io/tests to util/io_tests so that
the utilities code and tests build in the right order.

Also update the test Makefile.am files to include the appropriate libraries.

introduced a new ./configure option --enable-static-link to statically link executables while still building dynamic loadable modules correctly.
