Add a top_block parameter to control exception handling
This restores past behavior where the scheduler catches exceptions
raised in block threads, allowing flowgraphs to continue running after
the failure of an individual block. It also adds optional new behavior,
selected by setting catch_exceptions=False to the top block, which causes
exceptions to not be caught. In this mode of operation, a std::terminate
handler can be installed to print a stack trace before the flowgraph exits.
