[Freeciv-Dev] patch: rand module / code cleanup (PR#204)

[David Pfitzner <dwp@xxxxxxxxxxxxxx>]

Hi,

I had some free time recently so I made some patches for a
few things I wanted to do long ago.

This patch doesn't have any user-visible changes, but just
tidies the code up a bit.  It moves the myrand() stuff to a 
separate module, common/rand.[ch], and make some things 
slightly nicer IMO:  

Wraps random state variables up into a struct; avoids using 
globals/extern to save/restore random state in savefile; 
more flexible method to have multiple concurrent random 
sequences (replaces old save_restore_random() with 
get_myrand_state() and set_myrand_state()).
