Several large changes happen in this patch. The FDEntry class is rewritten so that file descriptors now correspond to types: 'File' which is normal file-backed file with the file open on the host machine, 'Pipe' which is a pipe that has been opened on the host machine, and 'Device' which does not have an open file on the host yet acts as a pseudo device with which to issue ioctls. Other types which might be added in the future are directory entries and sockets (off the top of my head). The FDArray class was create to hold most of the file descriptor handling that was stuffed into the Process class. It uses shared pointers and the std::array type to hold the FDEntries mentioned above. The changes to these two classes needed to be propagated out to the rest of the code so there were quite a few changes for that. Also, comments were added where I thought they were needed to help others and extend our DOxygen coverage.
