69973992d5 improve Vector<> safety checks
- make errors that will always cause a memory corruption always fatal
  (for eg: KeyedVector<>::editValue{For|At}() failure)
- make other errors fatal in debug mode, those that can be caught by
  the caller.
- fix typos

a9611c5d5b fix a corruption in Vector<> when adding new items
would happen when vectors are copied and new items is
added in both vectors. we didn't duplicate the underlying
storage when adding items in vectors.

c105333997 Minor code cleanups in vector.
Fixed a potential bug where calling replaceAt with a reference to
an existing element in the vector at the same index would cause
the element to be destroyed while being copied to itself.

Refactored the conditions in _grow and _shrink for clarity.
The computations are exactly the same but I think it reads better
this way.  In particular, the ssize_t variable 's' is gone: it didn't
need to be signed anyways because its value could never be negative.

686f62fcaf Replace Vector _grow/_shrink checks with assert.
On review of the code, _grow and _shrink are checking for conditions
that cannot happen and that don't even really make sense.  For
example, if _shrink is called with where + amount > mCount then
this is really bad, however the check only considered the case
when where >= mCount and then it would arbitrarily choose a new
value for where.  Huh?

As it happens, the callers are correctly validating the
arguments before passing them down to these methods so we can
get rid of this code.

f4a4ec2063 Even more native input dispatch work in progress.
Added more tests.
Fixed a regression in Vector.
Fixed bugs in pointer tracking.
Fixed a starvation issue in PollLoop when setting or removing callbacks.
Fixed a couple of policy nits.

Modified the internal representation of MotionEvent to be more
efficient and more consistent.

Added code to skip/cancel virtual key processing when there are multiple
pointers down.  This helps to better disambiguate virtual key presses
from stray touches (such as cheek presses).

e839a589bf Native input dispatch rewrite work in progress.
The old dispatch mechanism has been left in place and continues to
be used by default for now.  To enable native input dispatch,
edit the ENABLE_NATIVE_DISPATCH constant in WindowManagerPolicy.

Includes part of the new input event NDK API.  Some details TBD.

To wire up input dispatch, as the ViewRoot adds a window to the
window session it receives an InputChannel object as an output
argument.  The InputChannel encapsulates the file descriptors for a
shared memory region and two pipe end-points.  The ViewRoot then
provides the InputChannel to the InputQueue.  Behind the
scenes, InputQueue simply attaches handlers to the native PollLoop object
that underlies the MessageQueue.  This way MessageQueue doesn't need
to know anything about input dispatch per-se, it just exposes (in native
code) a PollLoop that other components can use to monitor file descriptor
state changes.

There can be zero or more targets for any given input event.  Each
input target is specified by its input channel and some parameters
including flags, an X/Y coordinate offset, and the dispatch timeout.
An input target can request either synchronous dispatch (for foreground apps)
or asynchronous dispatch (fire-and-forget for wallpapers and "outside"
targets).  Currently, finding the appropriate input targets for an event
requires a call back into the WindowManagerServer from native code.
In the future this will be refactored to avoid most of these callbacks
except as required to handle pending focus transitions.

End-to-end event dispatch mostly works!

To do: event injection, rate limiting, ANRs, testing, optimization, etc.

77e26d6822 fix [2542425] memory leak during video recording
[Sorted|Keyed]Vector<TYPE> would leak their whole storage when resized
from the end and TYPE had trivial dtor and copy operators.

caeddc7236 fix [2542425] memory leak during video recording
Vector::sort() is using _do_copy() incorrectly; _do_copy() calls the
copy constructor, not the assignment operator, so we need to destroy
the "destination" before copying the item.
