On crash the backtrace log in terminal output cannot be parsed by address resolver

[sabbath]

On crash the backtrace log in terminal output cannot be parsed, because the logger in https://github.com/espressif/esp-idf/bl ... _helpers.c does not put a space between the fist and second stacktrace enrty fieds.

I have fixed this problem in my local machine, just patch the debug_helpers.c (put the missing space character)

How can I craete a pull-request to contribute this patch?
