- removing static qualification on ompi_coll_tuned_sendrecv
- adding ompi_coll_tuned_isendrecv function which posts isend and irecv requests
These changes are separate from but necessary for new algorithms I am working on.

so there's no longer a race there (I used to do the unlock request last, after local completion of all the
requests completed, to try to avoid having the passive side reply to the active side, but I don't do that
anymore). The unlock side will not "unlock" the window until it actually receives the correct number of results,
so we're good there.
This fixes an issue where we would receive data on the remote side we weren't expecting that could cause
us to release a lock before it really should have been released to the requesting peer. It could also
cause a deadlock if one of the processes trying to unlock was "self", as that would result in the active
unlock never sending the unlock request, even though it sent the payload, which could cause a counter
that should always be positive to hit -1, causing an infinite loop that could only be solved by
popping up the stack, which was an impossibility.

Let's minimize the disturbances and say that the configure system is right.
From now on it's OPAL_BOOL_STRUCT_COPY. This one is related to r13076 and
has to follow when r13076 goes in the 1.2.

been fixed in the 7.0 PGI series, but is unlikely to be fixed in the
6.2 series:
* Add a configure test looking for the bad behavior (the PGI compiler
chokes on C code where structs containing bool's are copied by
value)
* Set OMPI_BOOL_STRUCT_COPY to 1 if it's ok, 0 if it's not (i.e., PGI
6.2 series will have this value set to 0)
* In two places in the code base -- orte-clean and btl_openib_ini.h,
we have a struct that contains a bool that is copied by value. In
these two places, check OMPI_BOOL_STRUCT_COPY and if it's 1, use
the "int" type instead of "bool".

- utilizing coll_tuned_util functions
- setting line length to 80.
This implementation uses standard send messages (instead of synchronous ones).
The change improved our performance over MX multiple number of times, however,
there exists a small potential that last message to be sent can be delayed
(until next mpi call, which means potentially infinitely).
If this shows to be a problem, I will modify the algorithms to use synchronous
send as last operation (which will incur performance penalty again).

This is somewhat limited currently for expample, if you have 3 ports on Node A and 5 ports
on Node B then the peers will use 3 ports to communicate with each other.
This is on a subnet basis, so for any pair of nodes we take the
intersection of the available ports within a subnet.
We use subnets to determine reachability for lazy connection establishment. So
if Node A and Node B each have two HCA's (on seperate networks) then the
subnet's must be distinct, otherwise we will try to wire up HCA's on seperate
networks.

* Make sure that the pval always writes to the correct portion of the
lval. This only matters on 32 bit big endian machines.
* On 32 bit machines when assigning to pval, the other 4 bytes of lval
weren't being written, which could lead to bogus data
We use macros so that there aren't casts all over the code and the pval
assignment can occur to the correct 4 bytes. Refs trac:587
