cb2dc1ba89 lib: use int type for more port variables
This is a follow-up to 764c6bd. Prior to that change port variables
were usually type long.

urldata: remove 'local_ip' from the connectdata struct

urldata: remove duplicate port number storage

still often used internally to signify "unknown value" and 0 - 65535 are

hostip: remove conn->data from resolver functions
This also moves the 'async' struct from the connectdata struct into the

away 1176 bytes (18%) from the Curl_easy struct that aren't used very

lib: pass in 'struct Curl_easy *' to most functions
... in most cases instead of 'struct connectdata *' but in some cases in
addition to.

- We mostly operate on transfers and not connections.

- We need the transfer handle to log, store data and more. Everything in
  libcurl is driven by a transfer (the CURL * in the public API).

- This work clarifies and separates the transfers from the connections
  better.

- We should avoid "conn->data". Since individual connections can be used
  by many transfers when multiplexing, making sure that conn->data
  points to the current and correct transfer at all times is difficult
  and has been notoriously error-prone over the years. The goal is to
  ultimately remove the conn->data pointer for this reason.

gopher: Implement secure gopher protocol.
This commit introduces a "gophers" handler inside the gopher protocol if
USE_SSL is defined. This protocol is no different than the usual gopher
prococol, with the added TLS encapsulation upon connecting. The protocol
has been adopted in the gopher community, and many people have enabled
TLS in their gopher daemons like geomyidae(8), and clients, like clic(1)
and hurl(1).

I have not implemented test units for this protocol because my knowledge
of Perl is sub-par. However, for someone more knowledgeable it might be
fairly trivial, because the same test that tests the plain gopher
protocol can be used for "gophers" just by adding a TLS listener.

altsvc: clone setting in curl_easy_duphandle
The cache content is not duplicated, like other caches, but the setting
and specified file name are.

Test 1908 is extended to verify this somewhat. Since the duplicated
handle gets the same file name, the test unfortunately overwrites the
same file twice (with different contents) which makes it hard to check
automatically.
