 Modified Files:
        src/sys/opencrypto: deflate.c
 
 Log Message:
 redo result buffer allocation, to avoid dynamic allocations:
 -use exponentially growing buffer sizes instead of just linear extension
 -drop the dynamic allocation of buffer metadata introduced in rev.1.8 --
  if the initial array is not sufficient something is wrong
 -apply some (arbitrary, heuristic) limit so that compressed data
  which extract into insane amounts of constant data don't kill the system
 This addresses PR kern/36864 by Wolfgang Stukenbrock. Some tuning
 might be useful, but hopefully this is an improvement already.
