KUDU-3647 more robust zlib wrapper code
This patch introduces much more robust error handling for both
zlib::{CompressLevel,Uncompress}() utility wrappers and fixes a few bugs
introduced along with other modifications in [1]. In addition, the code
now follows the documented API of zlib's inflate()/deflate() more
closely per docs [2] and example [3], while zlib::CompressLevel()
no longer allocates memory on the heap and uses a much smaller
stack-allocated buffer. It seems that using a larger heap-allocated
buffer inadvertently hid the improper usage of zlib's deflate() API.
This patch adds a few test scenarios to cover the main functionality
of zlib::CompressLevel() and zlib::Uncompress(), and also a few specific
conditions attributed to truncated and corrupted input data that's fed
to zlib::Uncompress().

> Support gzipped HMS notifications (GzipJSONMessageEncoder)
> ----------------------------------------------------------

> Key: KUDU-3201
> URL: https://issues.apache.org/jira/browse/KUDU-3201
> Project: Kudu
> Issue Type: Improvement
> Components: hms
> Affects Versions: 1.13.0
> Reporter: Grant Henke
> Assignee: Grant Henke
> Priority: Major
> Fix For: 1.14.0
>
>
> In HIVE-20679 a new message encoder was added to Hive that gzips and based64
> encodes notification messages. In HIVE-21307 the default encoder was changed
> to use the gzip encoder, GzipJSONMessageEncoder.
> Though Hive 4 is not released, failures as a result of this new message
> format were reported in IMPALA-8751. We should add support for the gzip
> format to prevent future HMS sync issues.
