PNFile class for unbuffered blocking file descriptor IO.

Only raw and fast POSIX open,read,write,seek calls on fd. fgets (aka readline) is only supported on stdin via the "read" method.

See also
the buffile library (PNBufFile) for buffered io via FILE* for fopen, fscanf, fprintf, fread, fgets see there.
the aio library (PNAio) for async non-blocking io, via libuv bindings.
