The check added to each non-object reads adds an overhead. If the
objects (binders and file descriptors) were written to the Parcel in
sequential order then check adds a small O(1) overhead to each read,
plus an O(N) overhead to the first read (to verify the N objects were
added in order).
If the objects were written out of order (as in by jumping around the
Parcel
with setDataPosition and writing Binder, DON'T DO THIS!!) (writing non
objects out of order is fine), the first read is forced to sort the
objects
in the internal bookkeeping. Based on the assumption non sequential
writes
are infrequent and overall Parcels are probably mostly sorted, insertion
sort was used. Worst case sorts will add an O(N^2) overhead to the first
non object read from the Parcel.

Due to more complex window layouts resulting in lots of overlapping
windows, the policy around FLAG_WINDOW_IS_OBSCURED has changed to
only be set when the point at which the window was touched is
obscured. Unfortunately, this doesn't prevent tapjacking attacks that
overlay the dialog's text, making a potentially dangerous operation
seem innocuous. To avoid this on particularly sensitive dialogs,
introduce a new flag that really does tell you when your window is
being even partially overlapped.
We aren't exposing this as API since we plan on making the original
flag more robust. This is really a workaround for system dialogs
since we generally know their layout and screen position, and that
they're unlikely to be overlapped by other applications.

The addition of ashmem size tracking can lead to parcel objects
overwriting other values on the stack in old binary blobs.

This is special solution only for emerald branch.
Changes including new const char* value/interface for sensor physical data. Sensor service and manager does not take care of content, structure or other
details of string. Sensor HAL is taking care of parsing data from string and setting values to Sensor HW.

Makes sure we don't change the memory layout of the Parcel class
to maintain binary compatibility with prebuilts linking against
libbinder.

sf: Always use opengles for screen capture
Go back to the usage of GRALLOC_USAGE_HW_TEXTURE and GRALLOC_USAGE_HW_RENDERER
in captureScreenImplLocked regardless of useReadPixels value
This fixes the EGL_NO_IMAGE_KHR error returned from
eglCreateImageKHR (blank images returned from screenshot path)
