The CancelFutureTest fails for libc++ because it uses two
emper::Semaphores to coordinate the involved fibers.

Using gcc and stdlibc++ the default constructor initialized the
semaphore count to 0.

The default constructor using clang and libc++ does not initialize the
semaphore count member and thus causing the CancelFutureTest to misbehave.

[ContextManager] Remove the put/get free context cycle

See merge request i4/manycore/emper!396

The put/get free context cycle in ContextManager::start() (if
continuation stealing is enabled) became unnecessary with
c66551bf ("[Context] Use 'jmp' instead of 'ret' to kickoff the
context").

Fix ContextManager with MemoryManager

See merge request i4/manycore/emper!395

Even though the MemoryManager is enabled for the ContextManager per
default, it never was actually used due a logic bug. Squash that bug!

In case a Context has been retrieved from the MemoryManager, without
it malloced, then we need to re-initialze some of the Context's values
before we can use the Context.

Kickoff context using 'jmp' instead of 'ret'
