[C++] ARROW-2826 Breaks parquet-cpp 1.4.0 builds

[asfimport]

The PR associated with ARROW-2826 removed PoolBuffer from the public API, which is used in parquet-cpp.

This means we cannot build parquet-cpp 1.4.0 against arrow master.

@wesm How would you like to handle this?

Antoine Pitrou / @pitrou:
@cpcloud This should have been fixed by PARQUET-1350, hasn't it?

Should we be building against a different version of parquet-cpp?

Phillip Cloud / @cpcloud:
It's that we're building against 1.4.0 in crossbow builds. I saw the parquet patch.

Antoine Pitrou / @pitrou:
Hmm, then I guess we should cut a parquet-cpp release soon?

Wes McKinney / @wesm:
Build parquet-cpp from master. That's what we have done in the past.

[asfimport]

Phillip Cloud / @cpcloud:
That would be ideal, but I don't have the time to cut releases of both arrow and parquet (nor the proper ASF karma/permissions) so someone else would have to do it. Barring that, that commit would have to be reverted as that is the only commit from arrow that blocks the build (there are other issues remaining with the builds, like boost version not being correct on wheel builds).

Phillip Cloud / @cpcloud:
@wesm Are we not shipping the parquet-cpp artifacts along with arrow artifacts in the release?
