Thread::getTid returns pid_t gettid() after run
This is needed when the parent or any other thread besides the child
needs access to the child's kernel tid.

Add C++ thread API androidGetThreadSchedulingGroup
This API is intended for applications that need to read a thread's
scheduling group, while using the higher-level (C++) family of thread APIs.

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.

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.

libutils Condition are now PRIVATE by default
Condition must be initialized with SHARED for the old behavior, where
they can be used accross processes.
Updated the two places android that require SHARED conditions.
PRIVATE conditions (and mutexes) use more efficient syscalls.

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.

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.

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.

some work to try to reduce the code size of some native libraries
- make sure that all binder Bn classes define a ctor and dtor in their respective library.
This avoids duplication of the ctor/dtor in libraries where these objects are instantiated.
This is also cleaner, should we want these ctor/dtor to do something one day.
- same change as above for some Bp classes and various other non-binder classes
- moved the definition of CHECK_INTERFACE() in IInterface.h instead of having it everywhere.
- improved the CHECK_INTERFACE() macro so it calls a single method in Parcel, instead of inlining its code everywhere
- IBinder::getInterfaceDescriptor() now returns a "const String16&" instead of String16, which saves calls to String16 and ~String16
- implemented a cache for BpBinder::getInterfaceDescriptor(), since this does an IPC. HOWEVER, this method never seems to be called.
The cache makes BpBinder bigger, so we need to figure out if we need this method at all.
