2021-10-15test: Remove using namespace in header filesHirokazu Honda
"using namespace" in a header file propagates the namespace to the files including the header file. So it should be avoided. This removes "using namespace" in header files in test.

2021-08-10libcamera: MappedFrameBuffer: Use typed Flags<MapModes>Kieran Bingham
Remove the need for callers to reference PROT_READ/PROT_WRITE directly from <sys/mman.h> by instead exposing the Read/Write mapping options as flags from the MappedFrameBuffer class itself. While here, introduce the <stdint.h> header which is required for the uint8_t as part of the Plane.

2021-08-10libcamera: Give MappedFrameBuffer its own implementationKieran Bingham
The MappedFrameBuffer is a convenience feature which sits on top of the FrameBuffer and facilitates mapping it to CPU accessible memory with mmap. This implementation is internal and currently sits in the same internal files as the internal FrameBuffer, thus exposing those internals to users of the MappedFramebuffer implementation. Move the MappedFrameBuffer and MappedBuffer implementation to its own implementation files, and fix the sources throughout to use that accordingly.

libcamera names header files based on the classes they define. The buffer.h file is an exception. Rename it to framebuffer.h.
