Remove the verbose #ifndef/#define/#endif pattern for maintaining
header idempotency, and replace it with a simple #pragma once.
This simplifies the headers, and prevents redundant changes when
header files get moved.
Tracepoints.h.in is not modified to use the pragma as it requires
self-inclusion.

MappedFrameBuffer::maps() returns planes_. This renames the function

MappedBuffer::maps()
MappedBuffer::maps() returns std::vector<MappedBuffer::Plane>.
Plane has the address, but the address points the beginning of the
buffer containing the plane.
This makes the Plane point the beginning of the plane. So
MappedBuffer::maps()[i].data() returns the address of i-th plane.

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.

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.
