Per MPI-3.1, ensure to raise an MPI exception with value
MPI_ERR_INFO_NOKEY if we try to MPI_INFO_DELETE a key that does not
exist. Thanks to @dalcinl (Lisando Dalcin) for raising the issue.

Adopting can fail if the server-side hole isn't available on the client.
We can fallback to other ways to load the topology.

There can be multiple [heap] consecutively in proc/<pid>/maps,
and there's no room between them.
Don't use a hole after the first [heap] is there's another [heap]
immediately after it.
This code would fail to find the last [heap] if there were multiple
[heap] interleaved with non-heap VMA, but our kind "after heap"
wouldn't be meaningful anymore anyway.

This commit has two changes
1. Adding magic string during handshake can cause
issue when used with older version of MPI. Hence set
RCVTIMEO paramter to 2 second
2. Using single call during handshake instead of
two calls

As part of improvement towards tcp debugging
we are moving few BTL_ERROR to show_help and also
update the function behaviour of
mca_btl_tcp_endpoint_complete_connect to return
SUCCESS and ERROR cases.

As part of improvement towards handling failure case
in btl tcp we are using magic string to verify mpi
connection. In case if there is mismatch or missing
magic string we can identify that we are trying to
connect with someother process.

Moving non-blocking send/receive function to btl_tcp
will help reusing these function where ever needed.
In this case we plan to reuse receive function to
retrive magic string to validate established connection
is from mpi process.

Someone posted an MTT test where libmpi_usempi_ignore_tkr.so ended
up with symbols like these being identifed as errors:
[error] MPI
[error] _Cmpi_fortran_status_ignore
[error] _Cmpi_fortran_statuses_ignore
those must be compiler-generated names so we shouldn't identify them
as problematic.

- change the increment used to test various no. of aggregators
to avoid using only power of two numbers
- convert some paratemers in the cost function from integers to
to floats for providing smoother and more consistent results
- set the FVIEW_IS_SET flag on the file *only* if the user
has set anything else than the default file view.

adjust how the aggregator nodes are selected depending on whether processes
have been mapped by node or anything else.
