Previously this code used a compile time constant, meaning that libcurl
always reported the libssh2 version that libcurl was built with. This
could differ from the libssh2 version actually being used. The new code
uses the CURL_LIBSSH2_VERSION macro, which is defined in ssh.h. The
macro calls the libssh2_version function if it is available, otherwise
it falls back to the compile time version.

- the data needs to be "line-based" anyway since it's also passed to the
debug callback/application
- it makes infof() work like failf() and consistency is good
- there's an assert that triggers on newlines in the format string
- Also removes a few instances of "..."
- Removes the code that would append "..." to the end of the data *iff*
it was truncated in infof()
Closes#7357
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.

... to avoid memory leaks!
libssh2 is tricky as we have to deal with the non-blockiness even in
close and shutdown cases. In the cases when we shutdown after a timeout
already expired, it is crucial that curl doen't let the timeout abort
the shutdown process as that then leaks memory!

Fixes#6990
After the recent conn/data refactor in this source file, this function
was mistakenly still getting the old struct pointer which would lead to
crash on servers with keyboard-interactive auth enabled.

Fixes#6691Closes#6782
If libssh2_knownhost_init() returns NULL, like in an OOM situation, the
ssh session was freed but the pointer wasn't cleared which made libcurl
later call libssh2 to cleanup using the stale pointer.

and rename it from 'ftp_list_only' since it is also used for SSH and
POP3. The state is updated internally for 'type=D' FTP URLs.
Added test case 1570 to verify.
Closes#6578
Since the set value then risks getting used like that when the easy
handle is reused by the application.
Also: renamed the struct field from 'ftp_append' to 'remote_append'
since it is also used for SSH protocols.
Closes#6579
Readdir data, filenames and attributes are strictly related to the
transfer and not the connection. This also reduces the total size of the
fixed connectdata struct.
Closes#6519
... 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.
Closes#6425
We currently use both spellings the british "behaviour" and the american
"behavior". However "behavior" is more used in the project so I think
it's worth dropping the british name.
