* rc/eunit-2.2.0:
  Updated to EUnit version 2.2.0

OTP-9505

  New macros assertNotMatch(Guard, Expr), assertNotEqual(Unexpected, Expr),
  and assertNotException(Class, Term, Expr).

  The debugMsg macro now also prints the pid of the current process.

  When testing all modules in a directory, tests in <Module>_tests.erl are
  no longer executed twice.

  The use of 'regexp' internally has been replaced with 're'.

Previously the test cases of all test suites (=modules) were put in
one and the same surefire report XML thereby breaking the principle of
least astonishment and making post analysis harder.  Assume the
following layout:

    src/x.erl
    src/y.erl
    test/x_tests.erl
    test/y_tests.erl

The results for both x_tests and y_tests were written to only one
report grouped under either module x or y (seemingly randomly).

Now two reports, one for module x and one for y are generated.
