1c92d7f388 test/addr: test that tor_lookup_hostname() handles IPv4 addresses 
And that it fails on IPv6 and host:port, and does something sensible with
host.

Tests for 30721.

60ce431c54 test/addr: Add some ambiguous IPv6 cases to test_addr_parse() 
Test some strings which could be parsed as IPv6 addresses,
or as IPv6:port strings.

adb8538e7b address/resolve: Require square brackets on IPv6 address:ports 
When parsing addreses via Tor's internal address:port parsing and
DNS lookup APIs, require IPv6 addresses with ports to have square
brackets.

But allow IPv6 addresses without ports, whether or not they have
square brackets.

Fixes bug 30721; bugfix on 0.2.1.5-alpha.

cd1de99468 resolve: consistently parse IP addresses in square brackets 
When parsing addreses via Tor's internal DNS lookup API:
* reject IPv4 addresses in square brackets (with or without a port),
* accept IPv6 addresses in square brackets (with or without a port), and
* accept IPv6 addresses without square brackets, as long as they have no port.

This change completes the work started in 23082, making address parsing
consistent between tor's internal DNS lookup and address parsing APIs.

Fixes bug 30721; bugfix on 0.2.1.5-alpha.

a7835202cf Turn several properties of types or variables into flags. 
"unsettable" is a property of types.  LINELIST_V and OBSOLETE are
unsettable, meaning that they cannot be set by name.

"contained" is a property of types.  I'm hoping to find a better
name here.  LINELIST_S is "contained" because it always appears
within a LINELIST_V, and as such doesn't need to be dumped ore
copied independently.

"cumulative" is a property of types. Cumulative types can appear
more than once in a torrc without causing a warning, because they
add to each other rather than replacing each other.

"obsolete" is a property of variables.

"marking fragile" is now a command that struct members can accept.

With these changes, confparse and config no longer ever need to
mention CONFIG_TYPE_XYZ values by name.

c60a85d22a Add a "typed_var" abstraction to implement lvalue access in C. 
Right now, this has been done at a high level by confparse.c, but it
makes more sense to lower it.

This API is radically un-typesafe as it stands; we'll be wrapping it
in a safer API as we do #30914 and lower the struct manipulation
code as well.

Closes ticket 30864.
