---------------------------------------

             Summary: [C++] Upgrade snappy to unreleased version
                 Key: ARROW-17283
                 URL: https://issues.apache.org/jira/browse/ARROW-17283
             Project: Apache Arrow
          Issue Type: New Feature
          Components: C++
            Reporter: Neal Richardson
             Fix For: 10.0.0


https://github.com/google/snappy/pull/148 was finally merged, so if we upgrade 
to the current HEAD, we will resolve the UBSan issues we've observed and can 
remove some test skips (in R at least). And I see 
https://github.com/google/snappy/commit/8dd58a519f79f0742d4c68fbccb2aed2ddb651e8
 as well, which may let us remove the {{ARROW_SNAPPY_OLD_BUILD_VERSION}} 
workaround too.

We could wait for an official snappy release, but they seem infrequent. Last 
one was over a year ago and there have been 2 sanitizer fixes we've upstreamed 
since then.
