Introducing a 'isproxy' argument to the connect function so that it
knows wether to store the time stamp or not.

The libssh2 backend has SSH session associated with the connection but
the callback context is the easy handle, so when a connection gets
attached to a transfer, the protocol handler now allows for a custom
function to get used to set things up correctly.

... 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.

... reuses the same dynamic buffer instead of doing repeated malloc/free
cycles.
Test case 100 (FTP dir list PASV) does 7 fewer memory allocation calls
after this change in my test setup (132 => 125), curl 7.72.0 needed 140
calls for this.
Test case 103 makes 9 less allocations now (130). Down from 149 in
7.72.0.
Closes#6004
... when continuing a transfer from a FETCH response.
When the size of the file was small enough that the entirety of the
transfer happens in a single go and schannel buffers holds the entire
data. However, it wasn't completely read in Curl_pp_readresp since a
line break was found before that could happen. So, by the time we are in
imap_state_fetch_resp - there's data in buffers that needs to be read
via Curl_read but nothing to read from the socket. After we setup a
transfer (Curl_setup_transfer), curl just waits on the socket state to
change - which doesn't happen since no new data ever comes.

It was used (intended) to pass in the size of the 'socks' array that is
also passed to these functions, but was rarely actually checked/used and
the array is defined to a fixed size of MAX_SOCKSPEREASYHANDLE entries
that should be used instead.

They serve very little purpose and mostly just add noise. Most of them
have been around for a very long time. I read them all before removing
or rephrasing them.

- no need to have them protocol specific
- no need to set pointers to them with the Curl_setup_transfer() call
- make Curl_setup_transfer() operate on a transfer pointer, not
connection
- switch some counters from long to the more proper curl_off_t type
Closes#3627
There is no real gain in performing memcmp() comparisons on single
characters, so change these to array subscript inspections which
saves a call and makes the code clearer.

The function does not return the same value as snprintf() normally does,
so readers may be mislead into thinking the code works differently than
it actually does. A different function name makes this easier to detect.

... and add "MAILINDEX".
As described in #2789, this is a suggested solution. Changing UID=xx to
actually get mail with UID xx and add "MAILINDEX" to get a mail with a
special index in the mail box (old behavior). So MAILINDEX=1 gives the
first non deleted mail in the mail box.

For pop3/imap/smtp, added test 891 to somewhat verify the pop3

For this, I enhanced the pingpong test server to be able to send back

Add a new type of callback to Curl_handler which performs checks on
the connection. Alter RTSP so that it uses this callback to do its
own check on connection health.
... all other non-HTTP protocol schemes are now defaulting to "tunnel
