Without this change, the directory of `javadoc` command must be
included in the `PATH` environment variable at `make`-time.
Paths of `javac`, `javah`, and `jar` commands are detected in
`configure`. So the path of `javadoc` also should be detected.

Parts of the pmix2x component called the event_* functions directly
instead of the opal_event_* wrappers. This is fine as long as we are
using libevent but becomes a problem with other event libraries.

A component with implementation of R. Rabenseifner's algorithm for Reduce and Allreduce.
This algorithm is a combination of a reduce-scatter implemented with recursive vector halving
and recursive distance doubling, followed either by a gather or an allgather.
Current limitations:
-- count >= 2^{\floor{\log_2 p}}
-- commutative operations only
-- intra-communicators onl

origin_datatype and target_datatype might be different and hence have different extent,
so use either origin_extent or target_extent when appropriate.

Start updating the various mappers to the new procedure. Remove the stale lama component as it is now very out-of-date. Bring round_robin and PPR online, and modify the mindist component (but cannot test/debug it).
Remove unneeded test
Fix memory corruption by re-initializing variable to NULL in loop
Resolve the race condition identified by @ggouaillardet by resetting the
mapped flag within the same event where it was set. There is no need to
retain the flag beyond that point as it isn't used again.
Add a new job attribute ORTE_JOB_FULLY_DESCRIBED to indicate that all the job information (including locations and binding) is included in the launch message. Thus, the backend daemons do not need to do any map computation for the job. Use this for the seq, rankfile, and mindist mappers until someone decides to update them.
Note that this will maintain functionality, but means that users of those three mappers will see large launch messages and less performant scaling than those using the other mappers.
Have the mindist module add procs to the job's proc array as it is a fully described module
Protect the hnp-not-in-allocation case

The osc_rdma_get_remote_segment() has the 3rd and 4th args as
* target_disp
* length
which it uses to determine if the rdma falls within the bounds of
the window or not (actually it only checks the upper bound, but I'm
okay with that).
Anyway the caller previously was passing in the length argument as
target_datatype->super.size * target_count
which which doesn't really represent the number of bytes after target_disp
for which data exists. In particular I could create a datatype as
{ disp -4, len 4 } and use target_disp 4
and that would be bytes 0-3 of the window where the original code
would think it was bytes 4-7 and could abort at the range check.
Ive changed it to use the opal_datatype_span() function.

Yalla has a macro PML_YALLA_INIT_MXM_REQ_DATA that checks if a datatype
is contiguous via opal_datatype_is_contiguous_memory_layout(dt,count)
and if so it selects a size and lb that presumably is what will rdma, as
ompi_datatype_type_size(_dtype, &size); \
ompi_datatype_type_lb(_dtype, &lb); \
This failed when I gave it a datatype constructed as [ ...] with extent 4.
What I mean by that datatype is
lens[0] = 3;
disps[0] = 1;
types[0] = MPI_CHAR;
MPI_Type_struct(1, lens, disps, types, &tmpdt);
MPI_Type_create_resized(tmpdt, 0, 4, &mydt);
So there are 3 chars at offset 1, and the LB is 0 and the UB is 4.
So that macro decides that size=4 and lb=0 and later I suppose size is getting
updated to 3 for the final rdma, and so a send of a buffer
[ 0 1 2 3 ] gets recved as [ 0 1 2 _ ]. I think it should use the true lb
and the true extent.
For "regular" contig datatypes it would be the same, and for the irregular
ones that are still deemed contiguous by that utility function it should
still be the right thing to use.

The --enable-new-dtags option for the compiler wrappers is
often great, but for some particular install/usage scenarios
causes issues.
This commit provides a new configury option to use of rpath
in the compiler wrappers, but disables the
use of --enable-new-dtags in the link line.
The new configury option is
--enable-wrappers-runpath
To disable use of --enable-new-dtags in the wrappers, add
--disable-wrappers-runpath
to the Open MPI configury line.

See bug report
https://github.com/open-mpi/ompi/issues/3548
If a 1sided test is launched -host hostA:2,hostB:1 some of the ranks
call allocate_state_single() and others call allocate_state_shared().
These functions were producing different values for module->state_size
but that's used when they lookup peer info from each other in
ompi_osc_rdma_peer_setup() so they need to all have matching
module->state_offset values.
This change adds a few unused bytes in the memory allocate_state_single()
creates so it matches.
