[httpc] Wrong Host header in IPv6 HTTP requests.

When a URI with a IPv6 host is parsed, the brackets that encapsulates
the nnn is removed. This value is then supplied as the host header.
This can cause problems with some servers.
A workaround for this is to use headers_as_is and provide the host
header with the requst call
To solve this a new option has been added, ipv6_host_with_brackets.
This option specifies if the host value of the host header shall include
the branckets or not. By default, it does not (as before).
