The GRALLOC_USAGE_PROTECTED flag that was used
earlier for content protection is also used for
some other use cases such as disabling of
screen captures. Define this new flag that
is explicitly used for allocating secured
buffers for DRM.

The flag GRALLOC_USAGE_PRIVATE_UNCACHED can be set in the
usage to allow it to be uncached. If not set, the buffer
will be cached by default.

Add support for external-only display. Layer buffers
marked with GRALLOC_USAGE_EXTERNAL_ONLY will be
displayed on external panel only, if available.
In addition if the layer buffer also has the flag
GRALLOC_USAGE_EXTERNAL_BLOCK then only that layer
will be displayed on external (During suspend).
When this mode is on, the default mirror mode for
external is stopped.

For secure content the MM heap should never be
mapped in userspace. Add a flag to avoid
doing this for rotator which does not need
userspace mapping.

given the width, height and color format.

If an uncached buffer is needed from gralloc, the
client must use the flag GRALLOC_USAGE_PRIVATE_UNCACHED

Since composition bypass uses MDP overlays, which
need physically contiguous memory, we cannot use
bypass in cases where the buffers are using ashmem
or other virtual memory. Hence, avoid bypass in
such cases.
