into the OPAL namespace, eliminating cases like opal/util/arch.c
testing for ompi_fortran_logical_t.
As this is processor- and compiler-related information
(e.g. does the compiler/architecture support REAL*16)
this should have been on the OPAL layer.
- Unifies f77 code using MPI_Flogical instead of opal_fortran_logical_t
- Tested locally (Linux/x86-64) with mpich and intel testsuite
but would like to get this week-ends MTT output
- PLEASE NOTE: configure-internal macro-names and
ompi_cv_ variables have not been changed, so that
external platform (not in contrib/) files still work.

Script to add the corresponding header in front of all following

- ompi/mca/btl/btl.h -- nclude _after_ #ifndef MCA_BTL_H
- ompi/mca/crcp/bkmrk/crcp_bkmrk_btl.c -- still no need for
orte/util/output.h

Studio compilers again. It has been broken since
1/14/2009 when some changes exposed a bug in autoconf
and how it handles support for the restrict keyword.
Basically, Sun Studio C supports the restrict keyword
but Sun Studio C++ does not.
I am also pursuing a fix with the autoconf folks, but
this change was needed to get things building again.

1. Galen's fine-grain control of queue pair resources in the openib
BTL.
1. Pasha's new implementation of asychronous HCA event handling.
Pasha's new implementation doesn't take much explanation, but the new
"multifrag" stuff does.
Note that "svn merge" was not used to bring this new code from the
/tmp/ib_multifrag branch -- something Bad happened in the periodic
trunk pulls on that branch making an actual merge back to the trunk
effectively impossible (i.e., lots and lots of arbitrary conflicts and
artifical changes). :-(
== Fine-grain control of queue pair resources ==
Galen's fine-grain control of queue pair resources to the OpenIB BTL
(thanks to Gleb for fixing broken code and providing additional
functionality, Pasha for finding broken code, and Jeff for doing all
the svn work and regression testing).
Prior to this commit, the OpenIB BTL created two queue pairs: one for
eager size fragments and one for max send size fragments. When the
use of the shared receive queue (SRQ) was specified (via "-mca
btl_openib_use_srq 1"), these QPs would use a shared receive queue for
receive buffers instead of the default per-peer (PP) receive queues
and buffers. One consequence of this design is that receive buffer
utilization (the size of the data received as a percentage of the
receive buffer used for the data) was quite poor for a number of
applications.
The new design allows multiple QPs to be specified at runtime. Each
QP can be setup to use PP or SRQ receive buffers as well as giving
fine-grained control over receive buffer size, number of receive
buffers to post, when to replenish the receive queue (low water mark)
and for SRQ QPs, the number of outstanding sends can also be
specified. The following is an example of the syntax to describe QPs
to the OpenIB BTL using the new MCA parameter btl_openib_receive_queues:
{{{
-mca btl_openib_receive_queues \
"P,128,16,4;S,1024,256,128,32;S,4096,256,128,32;S,65536,256,128,32"
}}}
Each QP description is delimited by ";" (semicolon) with individual
fields of the QP description delimited by "," (comma). The above
example therefore describes 4 QPs.
The first QP is:
P,128,16,4
Meaning: per-peer receive buffer QPs are indicated by a starting field
of "P"; the first QP (shown above) is therefore a per-peer based QP.
The second field indicates the size of the receive buffer in bytes
(128 bytes). The third field indicates the number of receive buffers
to allocate to the QP (16). The fourth field indicates the low
watermark for receive buffers at which time the BTL will repost
receive buffers to the QP (4).
The second QP is:
S,1024,256,128,32
Shared receive queue based QPs are indicated by a starting field of
"S"; the second QP (shown above) is therefore a shared receive queue
based QP. The second, third and fourth fields are the same as in the
per-peer based QP. The fifth field is the number of outstanding sends
that are allowed at a given time on the QP (32). This provides a
"good enough" mechanism of flow control for some regular communication
patterns.
QPs MUST be specified in ascending receive buffer size order. This
requirement may be removed prior to 1.3 release.

* Update TCP oob and btl with new interface

Per default this feature is disabled, to enable it you need to
configure with --enable-visibility and obviously you need a compiler

C and causes a warning when using PRI?64 macros. We
don't support versions prior to OS X 10.3, so we dont'
need such backward compatibility. Instead, redefine
the macros to be "ll", which is ANSI C and doesn't
cause a compiler warning.

One of the most important is the IOVBASE_TYPE which should be used
all over the places for casting to and from the iov_base field of
the iovec struct. The reason is because windows does not support
any kind of implicit conversion (not even through void*). All
conversions should be EXPLICIT.
