also lets us use strange/specific CXXFLAGS only when needed

only the spack package provides a pkgconfig file.  for other leveldb
installations we'll have to check for headers ourselves.

populaing a "kv_config.h" makes it easier to inspect what configure
thinks it found vs. looking through compiler command lines.

Add simple API for sending/receiving SSG ID and update test-mpi-group. The test-mpi-group app also has an example of how OID might be calculated when key is not already a hashed uint64_t value. Tested on Darwin.

Build/test fixups. Note that there are 2 workarounds in place so test-mpi-group terminates cleanly: the ssg_finalize in the kv-server shutdown_handler and the commented out margo_finalize in the kvgroup_client_deregister function.

First cut at adding distributed support. Implemented as separate client/server libs for now. Required some tweaking of the keyval API (see sds-keyval.h). May not compile yet.

Fixup parallel build issue and add test-client and test-server to the set of tests built automatically.

Simplify API. Handle arbitrary key/value types. Code still has explicit handling of bulk transfers. Unless this is a performance win, just let HG handle it all implicitly?

Did a "spack install leveldb" to pull stock leveldb into sds-repo. Decoupled sds-keyval from ParSplice build environment.

Take out "&" just to be sure copy constructor is called. May not be necessary given the core dumps seem to be related to a BwTree bug.
