Do not print anything when self-backtrace unavailable
Right now, gdb's self-backtrace feature will still print something
when a backtrace is unavailable:
sig_write (_("----- Backtrace -----\n"));
[...]
sig_write (_("Backtrace unavailable\n"));
sig_write ("---------------------\n");
However, if GDB_PRINT_INTERNAL_BACKTRACE is undefined, it seems better
to me to print nothing at all.
This patch implements this change. It also makes a couple of other
small changes in this same module: it adds a header guard to
bt-utils.h, and it protects the definitions of
gdb_internal_backtrace_1 with a check of GDB_PRINT_INTERNAL_BACKTRACE.
