[LITMUS^RT] liblitmus: prop/cpp-safe

[Glenn Elliott]

I pushed a very minor change to the forward declaration of litmus_open_lock() in liblitmus's litmus.h (prop/cpp-safe).  The declaration takes the parameter 'namespace'.  Of course, C++ compilers can't handle a keyword used as a parameter name. This patch changes 'namespace' to 'name_space'.  Note that this change is only limited to litmus.h.  The use of variables named 'namespace' in the .c test files remains unchanged.
