7ea904cbc0 Merge branch 'bug7011' 
Conflicts:
	src/or/circuitbuild.c

The conflict was trivial, since no line of code actually changed in
both branches: There was a fmt_addr() that turned into fmt_addrport()
in bug7011, and a "if (!n_conn)" that turned into "if (!n_chan)" in
master.

8419d18441 Use fmt_addrport where appropriate. 
This is mostly a conversion from this pattern:
	log("... %s:%d ...", fmt_and_decorate_addr(&addr), port);
to this:
	log("... %s ...", fmt_addrport(&addr, port));

The output is the same in all cases.

78e2d8c7a8 Add fmt_addrport. 
This function formats an addr:port pair, and always decorates IPv6
addresses.

4b0a039cb8 Use fmt_and_decorate_addr in extra-info "transport" lines. 
Apparently BridgeDB is already expecting transport lines to be formatted
thus; see https://trac.torproject.org/projects/tor/ticket/7011#comment:12 ff.
It may be that there are no extant IPv6 pluggable transport bridges yet,
so this didn't cause a problem.

5cbf0f2106 Use fmt_and_decorate_addr in TransportProxy statefile entry. 
state_transport_line_is_valid calls tor_addr_port_lookup, which expects
brackets around an IPv6 address. Without this, cached transport
addresses can't be parsed later:

[warn] state: Could not parse addrport.
[warn] state: State file seems to be broken.

See #7011.

41328c7009 Decorate addresses given to a HTTP CONNECT proxy. 
This affects the Request-URI and the value of the Host header. RFC 2616
doesn't directly address the formatting of IPv6 addresses, but it
delegates some productions to RFC 2396 "Uniform Resource Identifiers
(URI): Generic Syntax," which is obsoleted by RFC 3986, which requires
square brackets for IPv6 addresses in both places.

I tested this with
	HTTPSProxy 127.0.0.1:8000
	Bridge <IPv6 bridge>
	UseBridges 1
and an Ncat HTTP proxy:
	ncat --proxy-type http -l 8000 -vvv
