Subject: mtr: extend gdb backtace info

bt full - to include args and locals.

set print sevenbit on
  - it is more useful to be able to see the exact bytes
    (in case something is dumped as a string and not hexadecimal digits)
set print static-members off
  - there are many interesting (non-const) static members
set frame-arguments all
  - even non-printables are useful to see.

Let's make our bb logs give a little bit more detail on those
hard to reproduce bugs.

Tests on rhel7's gdb-7.6.1-120.el7
