cde/src/cmd/ksh93/tests/functions.sh
Martijn Dekker d7afb57c49 shtests: use central temporary directory; add --keep option 
This gets rid of repetitive code in test scripts to create their
own temporary directories. Instead, shtests exports a $tmp to each
test script that is a subdirectory of its own temporary directory.
This has the advantage of having all test script temporary
directories in one hierarchy. Along with a new option to keep
temporary files, this makes it easy to inspect them if wanted.

This does make the test scripts less self-contained as they now
depend on a temporary directory being exported as $tmp. But they
already depended on $SHELL being the shell to test, so they already
were not quite self-contained.

src/cmd/ksh93/tests/shtests:
- Add -k/--keep option to keep temporary directory. Make the EXIT
  trap report its location instead of deleting it.
- For each test, create a subdirectory of $tmp (named after the
  test script plus the tested locale or 'shcomp') and export that
  subdirectory to the test script as its own $tmp.
- If -k is not given, delete each script's temporary files
  immediately after running it to minimise disk usage.

src/cmd/ksh93/tests/*.sh:
- Don't make own temp directory.
- Refuse to run if $tmp is not set.
- Miscellaneous tweaks.
