btrace: Enable auxiliary instructions in record function-call-history.
Print the auxiliary data when a btrace_insn of type BTRACE_INSN_AUX
is encountered in the function-call-history. Printing is
active by default, it can be silenced with the /a modifier.
This patch is in preparation for the new ptwrite feature, which is based on
auxiliary instructions.
