Bugfixes

Shm: fix an issue in shmem region initialization, where a local region object would get created but immediately destroyed because a remote region object with the same ID already exists. Furthermore, the existing object would get marked as local, but with wrong configuration, leading to potential unexpected behavior. (by @rbx in https://github.com/FairRootGroup/FairMQ/commit/af0d668951f6f9dfbcc164e3a09ace1fe1a9f84e)

Misc

region example: add options for testing with externally-created regions by @rbx in https://github.com/FairRootGroup/FairMQ/commit/f5c46ce018486c5e9eb4ef0b0cef582a4ed9d709
shm: add some debug output by @rbx in https://github.com/FairRootGroup/FairMQ/commit/072d7cb7441d783497eded39ba7b09093e6f6a41
