we would leak a weakref_impl if a RefBase was never incWeak()'ed.
there was also a dangling pointer that would cause memory corruption
and double-delete when a custom destroyer was used to delay the
execution of ~RefBase.
it turns out that the custom destroyer feature caused most of the
problems, so it's now gone. The only client was SurfaceFlinger
who now handles things on its own.
RefBase is essentially back its "gingerbread" state, but the
code was slightly cleaned-up.

Bug: 5064702
Introduced the concept of an InputListener to further decouple
the InputReader from the InputDispatcher. The InputListener
exposes just the minimum interface that the InputReader needs
to communicate with the outside world. The InputReader
passes arguments to the InputListener by reference, which makes
it easy to queue them up.
Consolidated all of the InputReader locks into one simple global
Mutex. The reason this wasn't done before was due to potential
re-entrance in outbound calls to the InputDispatcher. To fix this,
the InputReader now queues up all of the events it wants to send
using a QueuedInputListener, then flushes them outside of the
critical section after all of the event processing is finished.
Removing all of the InputMapper locks greatly simplifies the
implementation.
Added tests for new stylus features such as buttons, tool types,
and hovering.
Added some helpers to BitSet32 to handle common code patterns
like finding the first marked bit and clearing it.
Fixed a bug in VelocityTracker where the wrong pointer trace
could get cleared when handling ACTION_POINTER_DOWN. Oops.
Changed PointerCoords so it no longer stores useless zero
axis values. Removed editAxisValue because it is not very
useful when all zero value axes are absent and therefore
cannot be edited in place.
Added dispatch of stylus hover events.
Added support for distance and tool types.

The built-in ZipFile class was quite a long time to find an unpack
libraries. Move everything to using the libutils ZipFileRO class that
goes quite a bit faster. Initial measurements are 6 times faster than
the Java code.
Also, read files off the disk and compare their CRC against the APK's
CRC to see if we need to write the new file to disk. This also cuts down
the bootup time by up to a second per APK that has native files.

Modified the touch input mapper to assign pointer ids sequentially
starting from 0 instead of using the tracking id or slot index
supplied by the driver. Applications should not depend on this
ordering but some do. (sigh)

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.

The version of MinGW we use doesn't have nrand48() which is really lame,
but we need to use libutils in the Windows SDK.

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.
