In abusive MPI communication patterns, sending a UDP ping only once a
second may not be sufficient -- all the UDP pings may be dropped. So
increase the frequency of the pings to every quarter second, and allow
more total pings to be sent.
Total timeout time is still the same (10 seconds) -- we'll just now
try 40 times (i.e., once every quarter second) as opposed to 10 times
(i.e., once a second). Testing has shown that this frequency allows
the connectivity checker to always succeed even in the many-to-one
abusive communication patterns.

We're passing a char foo[x] into PACK_BYTES, so we don't need to take
its address in the macro. This is parallel to the UNPACK_BYTES macro
(where we pass a char bar[x] into it, and don't take its address in
the macro).
The value we're packing is only used to output in a show_help message,
which is why this wasn't noticed before (i.e., it's not used in
network or addressing that would have caused a failure).

Per #4590, we now ''require'' the PROCEDURE keyword support in Fortran
for the mpi_f08 module. So if the Fortran compiler doesn't support
it, then we won't build the mpi_f08 module.

Use the new opal dstore API (vs. the old RTE DB API).

this to v1.8)

Not closing this file descriptor will cause us to leak file
descriptors. It is safe to close the file after it has been mmapped.

This commit was SVN r31579.
There's a requirement in several places (e.g., opal dstore) that
sizeof(ompi_process_name_t) -- which comes from the compile-time
selected ompi/mca/rte component -- is equal to sizeof(uint64_t). If
it's not, Bad Things will happen.
So put an assert here to catch that case.
This commit was SVN r31577.
Several fixes:
- I was allowing an MPI_T_cvar_handle to be created for an invalid
variable. Fixed this by checking if the variable is valid in
mca_base_var_get.
- Use a better error code when the caller tries to create an unbound
pvar handle for a bound variable.
- Return the verbosity level in MPI_T_cvar_get_info.

The old default context id maximum was committed to the trunk in
2006. After some discussion with Intel it appears this is restricting
the mtl to an arbirarly small number of communicators. Increasing the
default to allow up to 2^16 - 1 context ids.

feature
This commit should fix a hang seen when running some of the one-sided
tests. The downside of this fix is it reduces the maximum size of the
messages that use the fast boxes. I will fix this in a later commit.
To improve performance under a heavy load I introduced sequencing to
ensure messages are given to the pml in order. I have seen little-no
impact on the message rate or latency with this change and there is a
clear improvement to the heavy message rate case.
Lets let this sit in the trunk for a couple of days to ensure that
everything is working correctly.
