Perform a symbolic lookup of the addresses in the given string,
which are assumed to be the result of a prior calls to <code class="function">stack</code>,
<code class="function">callers</code>, and similar functions.
</p><p>
Returns a simple backtrace from the given hex string. One line per
address. Includes the symbol name (or hex address if symbol
couldn't be resolved) and module name (if found), as obtained from
<code class="function">symdata</code>. Includes the offset from the start of the function if
found, otherwise the offset will be added to the module (if found, between
brackets). Returns the backtrace as string (each line terminated by
a newline character). Note that the returned stack will be
truncated to MAXSTRINGLEN, to print fuller and richer stacks use
<code class="function">print_syms</code>.
