Fix inconsistencies in random number generation.

Browse source 
The srand()/rand() interface was being intermixed with the
srandom()/random() one.  The later is now used throughout.

Changed the srand() and rand() BIFs to work deterministically if Bro
was given a seed file (addresses #825).  They also now wrap the
system's srandom() and random() instead of srand() and rand() as per
the above.
