get_io_service deprecated and then removed in boost 1.70

rstudio/rstudio#4636

The previously deprecated get_io_context and get_io_service member functions have now been removed.
The previously deprecated service template parameters, and the corresponding classes, have now been removed.
Added a new async_result form with an initiate static member function.

Looks like .get_executor().context() should be used instead, and most usages of io_service should become io_context.

The following appears to fix issues. Works w boost 1.72

Replace io_service with io_context

Replace calls to get_io_service() with get_io_context()

The following works with the changes.
async_connect
async_query

Cannot get the following to compile. Something with the placeholders it seems
async_store_result

serial_port does not contain a get_io_context() using io_context instead of io_service.
