AArch64: Make graphics classes 64-bit compatible

This a merger of two commits submitted to AOSP by
the following authors:

ashok.bhat@arm.com, david.butcher@arm.coma
craig.barber@arm.com, kevin.petit@arm.com and
marcus.oakland@arm.com

Due to the very large number of internal conflicts, I
have chosen to cherry-pick this change instead
of letting it merge through AOSP because the merge
conflict resolution would be very hard to review.

Commit messages below:

================================================
AArch64: Make graphics classes 64-bit compatible

Changes in this patch include

[x] Long is used to store native pointers as they can
    be 64-bit.

[x] Some minor changes have been done to conform with
    standard JNI practice (e.g. use of jint instead of int
    in JNI function prototypes)

[x] AssetAtlasManager is not completely 64-bit compatible
    yet. Specifically mAtlasMap member has to be converted
    to hold native pointer using long. Added a TODO to
    AssetAtlasManager.java to indicate the change required.

AArch64: Use long for pointers in graphics/Camera

For storing pointers, long is used in
android/graphics/Camera class, as native
pointers can be 64-bit.

In addition, some minor changes have been done
to conform with standard JNI practice (e.g. use of
jint instead of int in JNI function prototypes)
