Nick Mathewson ede88c374c Disable the dump_desc() function.
It can be called with strings that should have been
length-delimited, but which in fact are not.  This can cause a
CPU-DoS bug or, in a worse case, a crash.

Since this function isn't essential, the best solution for older
Tors is to just turn it off.

Fixes bug 40286; bugfix on 0.2.2.1-alpha when dump_desc() was
introduced.

o Major bugfixes (denial of service):
- Disable the dump_desc() function that we used to dump unparseable
information to disk. It was called incorrectly in several places,
in a way that could lead to excessive CPU usage.
