dbghelp[1]: Speed up pool_alloc performance. Patch by Eric Pouech.

Current dbghelp has some performance problem if big debug files are 
involved (10MB or so)

		  mem1    time1   mem2    time2
current           54M     4.5s    146M    115s
after dbghelp[1]  54M     4.5s    167M    27s
after dbghelp[2]  52M     4.5s    92M     17s

I measured memory consupmtion and time it took for looking for an 
unknown symbol while WoW was in the debugger loaded. mem1/time1 is 
without big debug file. mem2/time2 is with big debug file.

dbghelp[1] increases memory consupmtion, because pool_realloc leaks more 
dbghelp[2] minimizes the memory leaks in pool_realloc and speeds up 
With the current pool implementation it's not possible to realloc memory 
without leaks. So I just minimize them.
