This patch disables the oshmem layer if there are no SPMLs that
will build. With the limited set of SPMLs available to support
oshmem, many builds end up installing an oshmem library that we
know will not work. There has been a bit of customer confusion
over oshmem, hopefully this will lead customers in the right
direction.

Two related changes to allow projects to not build based on
configure test results, as opposed to only reacting to
user configure options today. Use case is disabling a project
like oshmem because no communication channels can be built.
First, Move PROJECT_* AM_CONDITIONALs from the top of configure to
the bottom, so that we can change the results during configure.
Second, add a DIST_SUBDIRS to Makefile.am (and populate it in
opal_mca) so that "make dist" will work even when a project is
disabled.

enable_oshmem holds the result of a customer decision and, like
most user options, can have the values "yes" (user wants us to
build feature), "no" (user wants us not to build feature),
"" (user wants us to figure it out), and "<something>" (user
wants us to build feature, with <something> turned on).
This change updates oshmem to not lose this data by not overwriting
enable_oshmem with a yes/no and leaving the original customer
intent in place. Aside from fixing one bug (below) there are no
customer visible changes in this patch, but it makes it possible
to do the right thing in the upcoming work to allow oshmem to be
disabled based on test results.
There was a cosmetic bug in the existing code where specifying
a feature argument (like --enable-oshmem=awesome) would result
in the "checking if want oshmem" test reporting no, but oshmem
being built anyway. With this cleanup, the "checking if want
oshmem" test, the final output summary, and what actually happens
will all match.

Don't do a recursive search (hence no need for *idx anymore).
Find the level depth, to hide cache-issues first.
Then iterate over that level to find the objects we want.

df_search_min_bound() would need to be fixed for hwloc 2.0,
but it's only used in opal_hwloc_base_find_min_bound_target_under_obj()
which isn't used anymore. So just remove all of them.

Don't bother doing a lookup upwards or downwards for the target object type.
Just use the target depth, iterate over the level until we find the min_bound
object that intersects the locale cpuset.

Remove the MXM MTL, which has been deprecated in preference for
the Yalla PML. This was discussed at the last developers meeting
and somehow I ended up with the action item to do the removal.

The Java configury is split into two parts:
1. Determine if we want MPI Java bindings.
2. Find the Java compiler (and related).
This commit does a few things:
- Move the "Find the Java compiler" step from OPAL to OMPI (because
there is no Java in OPAL, and there doesn't appear to be any
immanent danger that there will be).
- As a direct consequence, remove the --enable-java CLI option
(--enable-mpi-java still remains). Enabling the MPI Java bindings
and enabling Java are now considered the same thing (since there
is no Java elsewhere in the code base, the different was
meaningless).
- Only invoke the "Find the Java compiler" step if we actually want
the MPI Java bindings.
- A few miscellaneous Java-related cleanups in configury (E.g., change
testing "$foo" == "1" to $foo -eq 1, etc.
This commit is mostly s/opal/ompi/gi in many places in configury and
shifting code around. But it looks bigger than it actually is because
of two reasons:
1. Some files were renamed:
* ompi_setup_java.m4 -> ompi_setup_mpi_java.m4 (setup MPI Java bindings)
* opal_setup_java.m4 -> ompi_setup_java.m4 (setup Java compiler)
2. Indenting level changed in (the new) ompi_setup_java.m4.

That PR accidentally changed Open MPI's build configuration infrastruc-

in https://github.com/open-mpi/ompi/pull/5001#issuecomment-387803012 and tracked down by me in https://github.com/open-mpi/ompi/pull/5001#issuecomment-387851005, abort your entire
in-progress Open MPI build when it failed to find an OS X/macOS JDK instead of
simply falling back to checking for a JDK in locations where it would be found
on other platforms. _Oops…!_

- rename ompi_coll_base_reduce_scatter_block_basic to
more self descriptive ompi_coll_base_reduce_scatter_block_basic_linear
- fix the description of the coll_tuned_reduce_scatter_block_algorithm
MCA param
this fixes and documents previous open-mpi/ompi@0e8b35b615
MPI_Reduce_scatter_block used to be implemented by the coll/basic module only.
A new algo (recursive doubling) was recently introduced and can be used via the coll/tuned module,
but we never intended to make it the default algo.
In order to "restore" the previous default, the initial algo was moved from coll/basic to coll/base,
and is now used by default by coll/tuned.
