CVS commit: src/sys/opencrypto

Module Name:    src
Committed By:   drochner

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.
