libibverbs-1.2.0-rc1 release

I have done a pre-release of the upcoming libibverbs-1.2.0 release.  The
code has been pushed to the official git repo and also an -rc1 tarball
uploaded to the https://ww.openfabrics.org/downloads/verbs download
area.  From the tag message:

tag libibverbs-1.2.0-rc1
Tagger: Doug Ledford <dledford-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org>
Date:   Wed Sep 23 12:47:04 2015 -0400

Ininitial roundup of 1.2.0 release items

- Add support for RoCE
- Add support for On Demand Paging
- No longer assume that no driver for a verbs device should be considered
  an error condition (usnic devices in particular are moving to libfabric
  drivers only, so we will emit a useless warning/error in the presence
  of usnic enabled machines)
- Harden some of the argument processing in example programs
- Add support for s390x
- Fix the broken create/destroy flow API
- First release under new management (hence the decision to update to
  version 1.2.0 instead of 1.1.9)

In particular, as this release fixes the create/destroy flow API, there
is a need for an updated libmlx4 sources in order to compile against the
fixed API (binary compatibility was maintained, but source compatibility
was not, so you will need the new libmlx4 to compile against the new
libibverbs).  Yishai, please post an updated libmlx4 head of repo and
preferably also a source tarball for libmlx4 when it's ready.
Preferably it would include an embedded check for the proper flow API in
your configure scripts.

An updated libmlx4 head was posted, changes match to above libibverbs 
items, specifically:
- Add RoCE IP based addressing support for UD QPs
- Add support for s390x
- Add support for TX/RX checksum offload
- Fixed the create/destroy flow API to match libibverbs
- Version was updated to match libibverbs - 1.2.0-rc1

The official git repo was updated on:
git://openfabrics.org/~yishaih/libmlx4.git

Doug, so when is this release expected to happen? the last release
took place in 2014.

Yishai, are you expecting anything to be added to libmlx4 for your
upcoming release?
if not, I guess you can sign it already against 1.2.0-rc1, right?

Or.

Doug, please be aware that currently there is a problem to build an rpm 
from the libibverbs git repository.

Major version number can't have hyphen "-". (e.g. "-rc1").
Also, version should be updated in libibverbs.spec.in.
You can use latest commits to libmlx4 as some reference for correct 
usage. (i.e. http://git.openfabrics.org/?p=~yishaih/libmlx4.git;a=summary).

No, the official libmlx4 git-repository is-up-to-date with the candidate 
stuff.

> if not, I guess you can sign it already against 1.2.0-rc1, right?
When there will be a formal release of libibverbs after fixing above 
issue, I'll build a matching libmlx4 tar ball.
