[PATCH v5 0/9] linux-user: Detect and report host crashes

[Richard Henderson]

More signal cleanups.  Mostly tested by temporarily adding an
abort, divide by zero, undefined instruction, null dereference,
within the implementation of a guest syscall to induce an error.

Changes for v5:
  * Remap guest abort, which means we need to try less hard on
    the host side to handle assertion failures.
  * Drop the backtrace.  Since backtrace_symbols only looks at the
    dynamic symbol set, we don't much that's useful -- we still
    need to use the debugger.
