[librdmacm,8/8] Open files with "close on exec" flag
File opened by librdmacm are not supposed to be inherited across
exec*(), most of the files are of no use for another program, and
others cannot be used without the associated memory mapping.
This patch changes fopen() open() and socket() to always set
close on exec flag.
This patch also add checks to configure to guess if fopen() supports
"e" flag. If O_CLOEXEC and SOCK_CLOEXEC are supported, fopen() should
support "e". If not supported, its discarded according to POSIX. Many
operating systems have support for fopen("e").
You might find more information about close on exec in the following articles:

http://danwalsh.livejournal.com/53603.html
- "Secure File Descriptor Handling" by Ulrich Drepper

Note: this patch won't set close on exec flag on file descriptors
created by the kernel for completion channel and such.
This is addressed by another kernel patch.

[librdmacm,5/8] configure: Use automake's option "subdir-objects"
Following advice in "Autotool Mythbuster" [1], option subdir-objects
can be used to have Makefiles create object files in the same
directory than theirs source files.
It reduces clobbering in the build directory.

[librdmacm,3/8] autogen.sh: Use autoreconf in autogen.sh
The old sequence of Autotools commands listed in autogen.sh is no
longer correct. Instead, just use the single "autoreconf" command,
which will invoke all the Right Autotools commands in the correct
order.

[librdmacm,2/8] Makefile.am: Fix an automake warning
Fix the following automake warning message:
Makefile.am:1: `INCLUDES' is the old name for `AM_CPPFLAGS' (or `*_CPPFLAGS')
A quote from the automake manual:
INCLUDES
This does the same job as AM_CPPFLAGS (or any per-target _CPPFLAGS variable
if it is used). It is an older name for the same functionality. This
variable is deprecated; we suggest using AM_CPPFLAGS and per-target
_CPPFLAGS instead.

[librdmacm,1/8] Add "foreign" option to AM_INIT_AUTOMAKE
Switch to the modern form of the AM_INIT_AUTOMAKE macro and tell
automake that the librdmacm package does not follow the GNU
standards. This change makes it possible to use 'autoreconf' for the
librdmacm package.

rsockets: Add ability to set the IB route directly
Add an RDMA specific rsocket option that allows the user
to program the RDMA route directly. This is useful
for apps that have path record data available, either
through the ibacm or SSA, and is needed by SSA itself
to connect over rsockets.

acm: Define needed ACM protocol messages
The librdmacm needs message definitions used to communicate
with the ibacm. It currently pulls these from infiniband/acm.h,
which is installed by ibacm. This creates an install order
dependency on ibacm. However, work on the scalable SA has
the ibacm using the librdmacm (via rsockets) for communication
between the different SSA components.
To resolve this issue, have the librdmacm define the message
structures that it needs to communicate with ibacm. The
librdmacm already has this through configuration checks. We
just expand that capability, which isolates the librdmacm
package from the ibacm package.
