After adding the subdir-objects automake option, the autotools will try
to create a directory called literally '$(top_srcdir)'/path/to/source
to store .Plo files.  with subdir-objects option, the top_srcdir and
top_builddir variables are no longer needed  (except in AM_CPPFLAGS and
linker commands).

*finally* gets hydra building again after yesterday's attempt to make
automake-1.14 happy

Use automake+libtool instead of simplemake+createshlib.  Parallel make
now works for real, and shared library creation should be more robust on
more platforms.  "make dist" now works, modulo building the documentation,
although for boring reasons we can't actually use it for the final
distribution tarball generation.

This is a massive change and without a doubt has some bugs in it.  We'll
work through them as we find them.

environment and overwrite it at the remote node, while allowing each
bootstrap server to specify exceptions. For example, ssh can specify
DISPLAY as an exception, and SLURM can specify all SLURM_ variables as
exceptions.

So far Hydra was assuming that the proxies always get launched
correctly, and can pass information about the launched MPI processes
(pids, exit status, etc.) reliably upstream. However, in cases where
there is a setup issue (e.g., if ssh is not configured properly), the
bootstrap forked processes might hang causing the upstream servers to
wait indefinitely for the proxies to connect back. We now handle this
case by forcefully cleaning up the local processes on a timeout or
SIGINT signal.

statically.
