Modified Files:
        src/sys/opencrypto: deflate.c deflate.h

Log Message:
-avoid allocation of an extra result buffer and data copy in case
 the DEFLATE complssion/decompression result is within a single
 buffer already
-simplify bookkeeping of allocated buffers (and don't waste the
 last member of the metadata array)
from Wolfgang Stukenbrock per PR kern/36865 (with some cleanup
of error handling by me)
The Gzip compression case can be improved too, but for now I've applied
the buffer bookkeeping changes.

tested with IP4 IPCOMP
