When this gets committed, can it be applied to both the 3.x and 4.x trees? Thanks, Charles

(The real number is 4802) An array sized on MAXMAGIS, that is reallocated every ALLOC_INTR lines of magic once MAXMAGIS is exceeded. The patch updates MAXMAGIS to 5000 (give a bit of room to grow) And makes ALLOC_INCR a variable that is bigger, and doubles every time it is used, to attenuate the problem if there ever ends up being 10000 entries in magic.
