Comment:

 Notes:
   * Changes file should mention the ticket number.
   * Commit message should mention the author.

   * parse_outbound_addresses has gotten really complicated, and full of
 duplicate code.  Maybe it's possible to refactor it to be cleaner?  This
 "adr_found[i]" stuff is fairly inelegant.
   * Would it make more sense to have the syntax be "OutboundBindAddress
 Exit 1.2.3.4" ?
   * conn_get_outbound_address falls back to the Exit address when the OR
 address is null.  That doesn't make sense to me.  Why did the user say
 OutboundBindAddressExit if they meant OutboundBindAddress?
   * Other outbound connection types are possible.  For example, directory
 connections, DNS lookups, and local connections to hidden services.
 Should those get handled too?  Should they get treated as if they were
 exit?
