Squashed: gralloc1/binder/requestor

This is a combination of the following three commits:

libui: Convert Allocator and Mapper to gralloc1

Converts GraphicBufferAllocator and GraphicBufferMapper to speak
gralloc 1.0 (via the C++ shim and optionally the 1On0 adapter) instead
of gralloc 0.x.

-----

Create graphic buffer using binder interfaces

Using binder interfaces rather than directly allocating the buffer prevents
SELinux warnings.

-----

Add requestor name to GraphicBuffer alloc metadata

Adds a requestor name (usually the BufferQueue consumer's name) to the
metadata that GraphicBufferAllocator stores on allocation so that
`dumpsys SurfaceFlinger` can attempt to attribute buffer usage to the
correct client.
