We were stuck in an infinite loop inside the rmaps round_robin
component when the user specified a host, then over subscribed it.
Instead of retuning an error, we looped forever.
For example:
$ cat hostfile
A slots=2 max-slots=2
B slots=2 max-slots=2
$ mpirun -np 3 --hostfile hostfile --host B
<hang>
The loop would not terminate because both host A and B are in the
'nodes' structure as they are both allocated to the job. However,
after allocating 2 slots to host B, we remove it from the node list
leaving us with a 'nodes' structure with just A in it. Since we can't
use host A, we keep looping here until we find a node that we can use.
This patch checks to make sure that if we get into this situation where
rmaps is looping over the list a second time without finding a node
during the first pass then we know that there are no nodes left to
use, so we have a resource allocation error, and should return to the user.
This patch should be moved to all of the release branches

the short version is that we shouldn't set O_NONBLOCK on standard I/O
file descriptors, so we no longer do.

option as discussed on the devel-core mailing list. The Big
Difference is that instead of hard-coding the strings "/lib" and
"/bin" in to append to the prefix, we append the basename of the local
libdir and bindir. Hence, if your libdir is $prefix/lib64, we'll
append /lib64 to construct the remote node's LD_LIBRARY_PATH (etc.).
Also appended the orterun.1 man page to include a description of
--prefix, how it is constructed, what it handles / what it does not,
etc.

able to kill the process. So just exit and save the error message.

- The constant 1 is a signed int by default. Explicitly say that
it is an unsigned value so we can't overflow
- Fix unreachable statement warnings in dss_arith by breaking out
of switch statements instead of returning - this should have
no impact on performance, since it's a non-conditional jump
- A couple of the GPR files had carriage returns and were in
DOS mode - put them in unix mode...
These should all probably go to the v1.1 branch...

* Add a platform spec for using the portals reference implementation's
RTE instead of our own to make local testing easier.
* Add a cnos rmgr component so that 1) we don't have to build nearly
as many components (no need for ras,rds,pls,etc.) and 2) calls
to MPI_ABORT() won't print error messages about not being able to
contact the daemon. Still need to fill in some of the terminate
stuff with calls from cnos, but will come in time.
* Make gpr_null use the base code for creating value and keyval
structures so that we don't segfault in ompi_mpi_init().

several errors (integer overflow in expression and comparison between signed and
unsigned). Casting the defines to the correct type solve these problems.
