description:
db_lstacktrace() can't use db_stacktrace_print and log() directly.

log() takes a 'int level' first argument, that must be supplied.
add an inline wrapper that calls vlog() with LOG_INFO, and the
supplied va_list.

(not noticed because this macro is not used anywhere in src but
i have a use in some uncommited code, that now failed to compile.)
