[PATCH 0/8] valgrind series

Yes, it has grown a little bit.

The main differences since last time:

- split out some parts that Peff thought were independent of valgrind

- added some convenience, such as "--tee" to output not only to the 
  terminal, but also to files named after the tests

- fixed half a bug in test-lib.sh (the templates were assumed to be 
  located relative to the binaries, not relative to the TEST_DIRECTORY)

- found the cause (sort of) of the spurious zlib "error".  Mark promised 
  that next zlib will contain a fix for that.

- tested.  A lot.

Note: I am not quite sure if the order is okay, but I really spent quite 
some time to reorder and resplit all the patches.

Jeff King (1):
  valgrind: ignore ldso and more libz errors

Johannes Schindelin (7):
  Add valgrind support in test scripts
  Valgrind support: check for more than just programming errors
  test-lib.sh: optionally output to test-results/$TEST.out, too
  t/Makefile: provide a 'valgrind' target
  Add a script to coalesce the valgrind outputs
  Tests: let --valgrind imply --verbose and --tee
  test-lib: avoid assuming that templates/ are in the GIT_EXEC_PATH
