58e012d1e3 Add Thread::join
This new API will be used by applications that previously used the
lower-level pthread APIs (including pthread_join).  Centralizing on the
Thread class instead of pthread will permit additional functionality to
be added later in only one location.

d9e1bb76fe Remove redundant memory barrier
pthread_create already includes the necessary memory barriers:
 - parent at pthread_create : pthread_mutex_unlock(start_mutex)
 - child at __thread_entry : pthread_mutex_lock(start_mutex)

Add lock around uses of mThread.

Added comments:
 - uses of mThread require lock
 - androidCreateRawThreadEtc returned ID is not safe for direct use from non-parent threads.

af1cf07134 Clean up use of HAVE_ANDROID_OS
HAVE_ANDROID_OS was defined as "1" for targets, but never defined as "0"
for non-targets. Changing them to #ifdef should be safe and matches
all the other uses of HAVE_ANDROID_OS throughout the system.

5ee1a0c5ee fix failing thread object run
A previously exited Thread object refuses to run again, if the
thread-id of the caller, conincides with the thread-id it previously
used in the worker thread. Hence reset the previously used worker
thread-id to -1 when it exits.

a017d5b379 Fix issue 3302649.
The cause of the problem is that AudioTrack::start() can fail if it is called from a newly created
thread that has the same ID as the AudioTrack callback thread that has just been stopped and not yet exited.
This is possible as the thread ID used by the Thread class is not the TID.

The fix consists in clearing the thread ID before exiting the thread loop.

7b0d45c346 Add system property to turn off scheduling groups.
Do this:

adb shell setprop debug.sys.noschedgroups 1

8c6cedc9bc Propagate background scheduling class across processes.
This is a very simply implementation: upon receiving an IPC, if the handling
thread is at a background priority (the driver will have taken care of
propagating this from the calling thread), then stick it in to the background
scheduling group.  Plus an API to turn this off for the process, which is
used by the system process.

This also pulls some of the code for managing scheduling classes out of
the Process JNI wrappers and in to some convenience methods in thread.h.

4de4ebf6a2 use broadcast() instead of signal() when signaling the condition-variable Thread::RequestExitAndWait() is waiting for
we could have several thread waiting on the condition and they all need to wake-up.
also added a debug "mTid" field in the class, which contains the tid of the thread (as opposed to pthread_t), this
is useful when debugging under gdb for instance.

ec0f1f6720 implement Mutex and Condition with pthread instead of calling futex directly.
internally pthread uses futex. the implementation consists of simple inlines
there are no implementation files anymore.
