Really Slick Screensavers GLX Port

The new lorenz screensaver in 0.8.3 doesn't build on Solaris, since its
"time" variable conflicts with the system time() function.

The errors reported by the Sun compiler:

"lorenz.cpp", line 68: Error: Multiple declaration for time.
"lorenz.cpp", line 245: Error: Formal argument t of type float in call to
coords_
at_time(float*, float, float*, float*, float*) is being passed extern "C"
long(*)
(long*).
"lorenz.cpp", line 246: Error: The operation "extern "C" long(*)(long*) +

"lorenz.cpp", line 488: Error: The operand "time" cannot be assigned to.
"lorenz.cpp", line 546: Error: The operand "*time" cannot be assigned to.

The attached patch is what we're using in the OpenSolaris packages to
resolve this, by renaming the time variable to "time_n" (for lack of a
better name).
