  tests: avoid several compiler warnings
  
  * tests/test-getcwd.c (main): Avoid buffer underflow.
  * tests/test-getdate.c (main): String literals are not safe with
  putenv, so use setenv.  Declare unused argument.
  * modules/getdate-tests (Depends-on): Add setenv.
  * tests/test-argv-iter.c (main): Declare unused argument.  Avoid
  problems with string literals in char *.
  * tests/test-hash.c (main): Avoid shadowing declaration.
  (insert_new): Treat string literals as char const *.
  * tests/test-getopt.h (test_getopt): Likewise.
  (getopt_loop): Alter types to minimize casting elsewhere.
  * tests/test-getopt_long.h (test_getopt_long, getopt_long_loop)
  (test_getopt_long_posix): Likewise.
  (do_getopt_long): Add wrapper to minimize casting.
  * tests/test-atexit.c (clear_temp_file): Use void.
  * tests/test-areadlink-with-size.c (main): Declare unused
  arguments.
