Don't use "0" as a "base" argument to tor_parse_*().

Telling these functions to autodetect the numeric base has lead to
trouble in the past.

Fixes bug 22469. Bugfix on 0.2.2.various.

o Minor bugfixes (format strictness):
- Restrict several data formats to decimal. Previously, the
BuildTimeHistogram entries in the state file, the "bw=" entries in the
bandwidth authority file, and process IDs passed to the
__OwningControllerProcess option could all be specified in hex or octal
as well as in decimal. This was not an intentional feature.
Fixes bug 22802; bugfixes on 0.2.2.1-alpha, 0.2.2.2-alpha, and
0.2.2.28-beta.
