Backtrace after malloc arena is corrupted
Without this change, if the malloc arena is corrupted and then
'backtrace' is called, the backtrace can crash because 'backtrace'
calls 'malloc'. For more, please see:
https://sourceware.org/ml/libc-alpha/2015-02/msg00678.html
* emacs.c (main): Initialize tables used by 'backtrace'.
* sysdep.c (emacs_backtrace): Document the newly used part of the API.
