  tests: rename 'tests/' => 't/', '*.test' => '*.sh'
  
  When we (soon) convert the Automake testsuite to a non-recursive
  make setup, we'll have to fix the entries of $(TESTS) to be
  prepended with the subdirectory they are in; this will increase
  the length of $(TESTS), and thus increase the possibility of
  exceeding the command-line length limits on some systems (most
  notably, MinGW/MSYS).  See automake bug#7868 for more information.
  
  Thus we rename the 'tests/' subdirectory to 't/', and each 'x.test'
  script in there to 'x.sh'; this way, the $(TESTS) entry 'foo.test'
  will become 't/foo.sh', which have the same number of characters.
