profile: Drop some unused code.

Commented out and not needed.

profile: Stop new threads and resume them with the debugger API.

If we don't stop new threads, then they can run before we
have a chance to start profiling them.

profiler: Actually support profiling user stack frames only.

The "-k" argument (which never did anything before) is now inverted
compared to what it used to be, i.e. now specifying it will profile

More refactoring:
* Renamed *ProfileResultImage to *ImageProfileResult.
* Separated the image result management from the *ProfileResult classes:
- The general per-thread image management functionality does now live in
Thread.
- Introduced interface ImageProfileResultContainer which is implemented by
Thread. An instance is passed to ProfileResult::AddSamples()/PrintResult().
* Made *ProfileResultImage independent of Image. The dependency is now to
SharedImage only.

* Scheduler/wait object listener:
- Moved scheduler listening interface to <listeners.h> and added more
convenient to use templatized notification functions.
- Added a listener mechanism for the wait objects (semaphores, condition
variables, mutex, rw_lock).
* system profiler:
- Hopefully fixed locking issues related to notifying the profiler thread
for good. We still had an inconsistent locking order, since the scheduler
notification callbacks are invoked with the thread lock held and have to
acquire the object lock then, while the other callbacks acquired the object
lock first and as a side effect of ConditionVariable::NotifyOne() acquired
the thread lock. Now we make sure the object lock is the innermost lock.
- Track the number of dropped events due to a full buffer.
_user_system_profiler_next_buffer() returns this count now.
- When scheduling profiling events are requested also listen to wait objects
and generate the respective profiling events. We send those events lazily
and cache the infos to avoid resending an event for the same wait object.
- When starting profiling we do now generate "thread scheduled" events for
the already running threads.
- _user_system_profiler_start(): Check whether the parameters pointer is a
userland address at all.
- The system_profiler_team_added event does now also contain the team's name.
* Added a sem_get_name_unsafe() returning a semaphore's name. It is "unsafe",
since the caller has to ensure that the semaphore exists and continues to
exist as long as the returned name is used.
* Adjusted the "profile" and "scheduling_recorder" according to the system
profiling changes. The latter prints the number of dropped events, now.

* Reorganized the image management. Introduced a SharedImage which knows the
symbols and is identified by name. Image does still represent a team-bound
image, but it refers to a SharedImage for the symbols, now. This allows us
to load the symbols for a shared object only once and share the data for all
teams referring to it.
* Made the area used for system profiling writable. "-a -f" would segfault
since the return addresses are sorted in-place.
