G_MAXRAND, rand(), srand(), lrand48(), srand48(), random(),
srandom(), RAND_FUNC and SRAND_FUNC to the appropriate g_rand*
equivalent. Programs which require seed setting for reproducible
results, and anything in the core, gets a dedicated GRand * for
the lifetime required. Programs which only ever used random
numbers for tossing a coin, rolling a dice, etc use g_random
functions. For the rest, judgement was used. Where it was easy, a
GRand * object was used and g_rand_* functions were
preferred. This fixes bug #67386 in HEAD.
