8119c970db Improve the connection algorithm for MX. There are 2 problems here: 
- first we setup the connections in the begining with all the peers
- MX does not handle well the case where several peers make connections to the same
  destination simultaneously.

So I change the order in which we connect. First we compute our rank in the array,
then in a round-robin fashion we setup connection starting with our left neighboard.

dc1ad885d1 Move the output message outside the loop. We print an error message only once when we fail to 
connect to a peer. Bonus, we print some additional informations like its MAC Address or name
if it's on our tables.

b0def3f6bf MX has 2 limitations regarding the iovecs. First they do not support iovec witha total size 
larger than 32K for inter-nodes transfert ... and then they do not support iovecs larger than
16K for inter-node transfert. Therefore we have to set the size of our first fragment to
16K to match both cases.

0f04132b13 mx_connect in the MX documentation is supposed to take a timeout in seconds. However, in real life it seems that the timeout should be in micro-second.

7b20370306 * pretty-print an error message if a btl component loads but can't find 
any NICs to use
* Make mvapi, gm, and mx components all publish information, even if there
  are no NICs available so that modex_recv doesn't hang.  If there are no
  NICs available, don't set the reachable bit, but don't do anything
  to fail.  This unfortunately doesn't cover the hangs that will result if
  different procs load different sets of components, but it's a start

ed56e743b7 * update configure.ac to use the modern version of AC_INIT and 
AM_INIT_AUTOMAKE, instead of the deprecated version.
* Work around dumbness in modern AC_INIT that requires the version
  number to be set at autoconf time (instead of at configure time, as
  it was before).  Set the version number, minus the subversion r number,
  at autoconf time.  Override the internal variables to include the r
  number (if needed) at configure time.  Basically, the right thing
  should always happen.  The only place it might not is the version
  reported as part of configure --help will not have an r number.
* Since AM_INIT_AUTOMAKE taks a list of options, no need to specify
  them in all the Makefile.am files.
* Addes support for subdir-objects, meaning that object files are put
  in the directory containing source files, even if the Makefile.am is
  in another directory.  This should start making it feasible to
  reduce the number of Makefile.am files we have in the tree, which
  will greatly reduce the time to run autogen and configure.

but are not that bad either.
