Tests for L{twisted.internet.defer.inlineCallbacks}.
These tests are defined in a non-C{test_*} module because they are
syntactically invalid on python < 2.5. test_inlinecb will conditionally import
these tests on python 2.5 and greater.
Some tests for inlineCallbacks are defined in L{twisted.test.test_defgen} as
well: see U{http://twistedmatrix.com/trac/ticket/4182}.

It's possible for L{returnValue} to be (accidentally) invoked at a stack
level below the L{inlineCallbacks}-decorated function which it is exiting.
If this happens, L{returnValue} should report useful errors.
If L{returnValue} is invoked from a function not decorated by
L{inlineCallbacks}, it will emit a warning if it causes an
L{inlineCallbacks} function further up the stack to exit.

This method mistakenly invokes L{returnValue}, despite the fact that it
is not decorated with L{inlineCallbacks}.

Flush the current warnings and assert that we have been told that
C{mistakenMethod} was invoked, and that the result from the Deferred
that was fired (appended to the given list) is C{mistakenMethod}'s
result. The warning should indicate that an inlineCallbacks function
called 'inline' was made to exit.

L{returnValue} will emit a non-local exit warning in the simplest case,
where the offending function is invoked immediately.

L{returnValue} will emit a non-local warning in the case where the
L{inlineCallbacks}-decorated function has already yielded a Deferred
and therefore moved its generator function along.
