Re: Preparing for 0.155

I don't want to rush on any API/ABI additions.  Also note I will be out
and incommunicado from this Friday through September 5th.  So if you
want a release soon (which I think is a fine thing), we should just tie
up the pure fixes and backend additions this week and let more additions
wait for the next release.

Upcase ELF.

This is just a bug fix and I don't think it needs to be described this way.

This is a problematic addition that opens new security issues in the
tools.  Since DWZ is not yet in wide use, if we want to make a release
soon perhaps we should disable some of this support.  It's also an
extreme API layering violation.  Doing this in a responsible way needs
much more thought, so I think the only right thing to do for an imminent
release is to disable the libdw support entirely.
