binder: Fix ABI incompatibility between older and newer compilers

Parcel::writeString16's first parameter was a char16_t - defined to
uint16_t somewhere else.

With ISO C++11 compatible compilers, however, char16_t is a
compiler-defined-type that is not necessarily unsigned.

This causes the symbol to be different, breaking support for talking
to binary blobs built with pre-ISO C++11-compilers, such as the
Galaxy Nexus RIL.

singleton: fix build for qcom display
frameworks/native/opengl: Fix build with gcc 4.8

In gcc 4.8, the warning for unused parameters (such as JNIEnv* pointers
in JNI functions that don't need it) is enabled by default - causing
-Werror to break the build.
