Namespace protect macros

[jrefice]

The macros in FC4SC aren't protected with a common prefix:

#define GET_SCP_MACRO(_1,_2,NAME,...) NAME
#define SCOPE_DECL(...) GET_SCP_MACRO(__VA_ARGS__,SCOPE_2ARG,SCOPE_1ARG)(__VA_ARGS__)
#define SCOPE_1ARG(t_name) \
#define SCOPE_2ARG(t_name,p_name) \
#define CG_CONS_DECL(type, args...) \
#define CG_CONS_DEF(type, args...) \
#define CG_CONS(type, args...) \
#define CG_SCOPED_CONS_DECL(type, scp_type, args...) \
#define CG_SCOPED_CONS_DEF(type, scp_type, args...) \
#define CG_SCOPED_CONS(type, scp_type, args...) \
#define CG_SCOPED_INST(name, args...) \
#define SAMPLE_POINT(variable_name, cvp) variable_name = static_cast<decltype(variable_name)> \
#define CREATE_WRAP_F(expr, type) [&]() -> type { return (expr); }
#define GET_CVP_MACRO(_1,_2,_3,_4, NAME,...) NAME
#define COVERPOINT(...) GET_CVP_MACRO(__VA_ARGS__, CVP_4, CVP_3)(__VA_ARGS__)
#define CVP_3(type, cvp_name, sample_expr) \
#define CVP_4(type, cvp_name, sample_expr, sample_cond) \
#define UCIS_PRINTER_HPP

This means that we could get various naming conflicts. These should all be protected with a common prefix (likely FC4SC_).
