#4 Macro namespace sometimes missing

[Renaud]

Some macros defined in header files are missing the VIDEOD namespace prefix. For example, DeviceMulticam.h defines NSURFACES.

Include guards also miss the VIDEOD namespace, e.g. videod/Client.h starts with

#ifndef _CLIENT_H_
#define _CLIENT_H_

when

#ifndef _VIDEOD_CLIENT_H_
#define _VIDEOD_CLIENT_H_

would be better.
