acf18e4265 libcamera: Switch from utils::make_unique to std::make_unique
Now that we're using C++-14, drop utils::make_unique for
std::make_unique.

007517618c ipa: Switch to FrameBuffer interface
Switch the IPA interfaces and implementations to use the Framebuffer
interface.

- The IPA interface is switched to use the simpler FrameBuffer::Plane
  container when carrying dmabuf descriptions (fd and length) over the
  pipeline/IPA boundary.

- The RkISP1 IPA implementation takes advantage of the new simpler and
  safer (better control over file descriptors) FrameBuffer interface.

d7e0985ce1 ipa: Allow short-circuiting the ipa_context_ops
When an IPA module is loaded without isolation and implements the
IPAInterface internally, going through ipa_context_ops is a waste of
time. Add an operation to retrieve the IPAInterface, and use it directly
in the IPAContextWrapper.

For debugging purpose, make it possible to forcing usage of the C API by
defining the LIBCAMERA_IPA_FORCE_C_API environment variable.

132d99bc8f ipa: Switch to the plain C API
Switch IPA communication to the plain C API. As the IPAInterface class
is easier to use for pipeline handlers than a plain C API, retain it and
add an IPAContextWrapper that translate between the C++ and the C APIs.

On the IPA module side usage of IPAInterface may be desired for IPAs
implemented in C++ that want to link to libcamera. For those IPAs, a new
IPAInterfaceWrapper helper class is introduced to wrap the IPAInterface
implemented internally by the IPA module into an ipa_context,
ipa_context_ops and ipa_callback_ops.
