* Add a configure time option to rename libmpi(_FOO).*
- `--with-libmpi-name=STRING`
* This commit only impacts the installed libraries.
Internal, temporary libraries have not been renamed to limit the
scope of the patch to only what is needed.
For example:
```shell
shell$ ./configure --with-libmpi-name=wookie
...
shell$ find . -name "libmpi*"
shell$ find . -name "libwookie*"
./lib/libwookie.so.0.0.0
./lib/libwookie.so.0
./lib/libwookie.so
./lib/libwookie.la
./lib/libwookie_mpifh.so.0.0.0
./lib/libwookie_mpifh.so.0
./lib/libwookie_mpifh.so
./lib/libwookie_mpifh.la
./lib/libwookie_usempi.so.0.0.0
./lib/libwookie_usempi.so.0
./lib/libwookie_usempi.so
./lib/libwookie_usempi.la
shell$
```
This commit improves and corrects error handling. In
cases where existing objects are altered after a call
to ompi_java_exceptionCheck, the results of the exception
check method are checked. In the case of an exception,
memory is cleaned up and the code returns to Java without
altering existing objects.

Fixed an error where if there were no MPI exceptions, a
JNI error could still exist and not get handled.

Per discussion on https://github.com/open-mpi/ompi/pull/1767 (and some
subsequent phone calls and off-issue email discussions), the PSM
library is hijacking signal handlers by default. Specifically: unless
the environment variables `IPATH_NO_BACKTRACE=1` (for PSM / Intel
TrueScale) is set, the library constructor for this library will
hijack various signal handlers for the purpose of invoking its own
error reporting mechanisms.
This may be a bit *surprising*, but is not a *problem*, per se. The
real problem is that older versions of at least the PSM library do not
unregister these signal handlers upon being unloaded from memory.
Hence, a segv can actually result in a double segv (i.e., the original
segv and then another segv when the now-non-existent signal handler is
invoked).
This PSM signal hijacking subverts Open MPI's own signal reporting
mechanism, which may be a bit surprising for some users (particularly
those who do not have Intel TrueScale). As such, we disable it by
default so that Open MPI's own error-reporting mechanisms are used.
Additionally, there is a typo in the library destructor for the PSM2
library that may cause problems in the unloading of its signal
handlers. This problem can be avoided by setting `HFI_NO_BACKTRACE=1`
(for PSM2 / Intel OmniPath).
This is further compounded by the fact that the PSM / PSM2 libraries
can be loaded by the OFI MTL and the usNIC BTL (because they are
loaded by libfabric), even when there is no Intel networking hardware
present. Having the PSM/PSM2 libraries behave this way when no Intel
hardware is present is clearly undesirable (and is likely to be fixed
in future releases of the PSM/PSM2 libraries).
This commit sets the following two environment variables to disable
this behavior from the PSM/PSM2 libraries (if they are not already
set):
* IPATH_NO_BACKTRACE=1
* HFI_NO_BACKTRACE=1
If the user has set these variables before invoking Open MPI, we will
not override their values (i.e., their preferences will be honored).

Since OS X 10.11 (aka El Capitan) DYLD_LIBRARY_PATH is no more
propagated to children, so try to dlopen libmpi with the full path
using the directory of libmpi_java

This commit does two things. It removes checks for C99 required
headers (stdlib.h, string.h, signal.h, etc). Additionally it removes
definitions for required C99 types (intptr_t, int64_t, int32_t, etc).

This commit also adds protection against negative error codes in ompi
error code functions. There is one outstanding issue. There is a
negative MPI error code defined in mpi.h. This will need to be fixed
separetely.
This commit fixes coverity IDs 1271533 and 1270156.

The sargs array and its elements were malloced but not freed. Note
that strings passed to NewStringUTF are copied into Java's heap and it
is the callers responsibility to free the original string.

Please verify your components have been updated correctly. Keep in
mind that in terms of threading:
OPAL_FREE_LIST_GET -> opal_free_list_get_st
OPAL_FREE_LIST_RETURN -> opal_free_list_return_st
I used the opal_using_threads() variant anytime it appeared multiple
threads could be operating on the free list. If this is not the case
update to _st. If multiple threads are always in use change to _mt.
libmpi.<OPAL_DYN_LIB_SUFFIX>, where OPAL_DYN_LIB_SUFFIX was determined
by configure.
Thanks to Ömer Demirel for reporting the issue.
Refs trac:3905.
This commit was SVN r29676.
The following Trac tickets were found above:
Ticket 3905 --> https://svn.open-mpi.org/trac/ompi/ticket/3905
Includes all MPI functions supported by Open MPI, including MPI-3
functions (as of about 2 weeks ago). Many changes compared to the
prior generation of Java bindings; not much is left from the prior
generation, actually. The changes include (but are not limited to):
* Add support for more than just a subset of MPI-1 functions
* Use typical Java case for symbol names
* Support Java Direct buffers (giving darn-near "native C"
performance)
* Support "type struct" better than the prior generation
* Make more of an effort for the Java bindings to be a thin layer
over the back-end C bindings
* ...and more
A proper README with more information about what is supported, how to
use these bindings, etc. will be committed shortly.
This commit was SVN r29263.
