bug#24617: 26.0.50; Handlers in `condition-case' should have programmatic access to the backtrace |

Currently a handler in a `condition-case' form doesn't have access to
the backtrace that was active when the signal was raised. This makes
many useful things impossible, such as re-raising signals or returning
the backtrace to emacsclient. I suggest either adding true exception
objects (storing the error symbol, data, and backtrace), or at least
providing a dynamic variable with the current backtrace.
