dma-buf: Add dma-buf heaps framework
This framework allows a unified userspace interface for dma-buf
exporters, allowing userland to allocate specific types of memory
for use in dma-buf sharing.
Each heap is given its own device node, which a user can allocate
a dma-buf fd from using the DMA_HEAP_IOC_ALLOC.
This code is an evoluiton of the Android ION implementation,
and a big thanks is due to its authors/maintainers over time
for their effort:
Rebecca Schultz Zavin, Colin Cross, Benjamin Gaignard,
Laura Abbott, and many other contributors!
