* waf: update to 2.0.23
* dma-heap: Add support for uncached dma-heap memory
imx_dma_buffer_dma_heap_allocator_new_from_fd() is
a new function that partially deprecates the dma_heap_fd
argument of imx_dma_buffer_dma_heap_allocator_new().
* Add sync access functions to ensure cache
coherency when allocating cached DMA memory;
only done by dma-heap allocator at this time
* Relax buffer mapping flags checks
* Add API functions to retrieve dma-heap / ION FDs

With the imx6 and imx7 kernel configurations changed to have ION enabled,
all imx machines that libimxdmabuffer supports are capable of using ION.

The i.MX8 QuadMax and QuadXPlus SoCs can use the ION allocator.
Also, if there is a DPU, then G2D will be emulated via the DPU. However,
the emulation's allocation functions are broken, so disable the G2D
allocator then.

Due to https://github.blog/2021-09-01-improving-git-protocol-security-github/#no-more-unauthenticated-git
it is required to use https protocol for github repo accessing.

libimxdmabuffer provides an API for allocating and handling physically
contiguous buffers ("DMA buffers") on imx6, imx7, imx8 machines with the
imx-kernel. The underlying allocation can be backed by the PxP, IPU, ION,
DWL, G2D APIs.
The API is backend agnostic. The same structures and functions can be used
with the underlying PxP and IPU allocators for example. Furthermore, the
library defines a "default" allocator (which one is the "default" is
determined by the library and by the build configuration).
By using this API, libraries can use compatible types for exchanging
DMA buffers in userspace, and can also use the same API and support mx6,
mx7, and mx8 machines, without requiring platform specific code changes.
