Support for a defaults torrc file.

This will mainly help distributors by giving a way to set system or package
defaults that a user can override, and that a later package can replace.

No promises about the particular future location or semantics for this:
we will probably want to tweak it some before 0.2.3.x-rc

The file is searched for in CONFDIR/torrc-defaults , which can be
overridden with the "--defaults-torrc" option on the command line.
