gunzip: limit uncompressed buffer size to 1032x compressed size
gunzip: limit uncompressed buffer size to 1032x compressed size

Don't allocate an obviously-too-large buffer for uncompressed data if
ISIZE becomes corrupted in a small file.  This isn't too effective, as
we still must allow over 1000x expansion, but we might as well do this.
