style fixes for panic_ functions
* panic.h (panic_impossible, panic_if, panic_unless): If NDEBUG is
defined, define away using "do { } while (0)" so that a semicolon is
always required. Also allow panic_impossible to be defined away if
NDEBUG is defined.
* lo-error.h (liboctave_panic_impossible, liboctave_panic_if,
liboctave_panic_unless): Likewise.
