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.

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
- Reorder some internal struct members so that less padding is used.
This is an attempt at saving a bit of space by packing some structs
(using pahole to find the holes) where it might make sense to do
so without losing readability.
I.e., I tried to avoid separating fields that seem grouped
together (like the cwd... fields in struct ftp_conn for instance).
Also abstained from touching fields behind conditional macros as
that quickly can get complicated.

Since curl's own memory debugging system redefines free() calls to track
and fiddle with memory, it cannot be used on memory allocated by 3rd
party libraries.
Third party libraries SHOULD NOT require free() to release allocated
resources for this reason - and libs can use separate healp allocators
on some systems (like Windows) so free() doesn't necessarily work
anyway.

... 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.
Closes#6395
Build breaks because the http_proxy field is missing:
vssh/libssh2.c:3119:10: error: 'struct connectdata' has no member named 'http_proxy'
Regression from #6021, shipped in curl 7.73.0
Closes#6125
The debug output used ssherr instead of sftperr which not only outputs
the wrong error code but also casues a warning on Windows.

In my very basic test that lists sftp://127.0.0.1/tmp/, this patched
code makes 161 allocations compared to 194 in git master. A 17%
reduction.
Closes#5336
Previously, options set explicitly through command line options could be
overridden by the configuration files parsed automatically when
ssh_connect() was called.
By calling ssh_options_parse_config() explicitly, the configuration
files are parsed before setting the options, avoiding the options
override. Once the configuration files are parsed, the automatic
configuration parsing is not executed.

From libssh 0.9.0, ssh_key_type() returns different key types for ECDSA
keys depending on the curve.

Previously, it was not possible to get a known hosts file entry due to
the lack of an API. ssh_session_get_known_hosts_entry(), introduced in
libssh-0.9.0, allows libcurl to obtain such information and behave the
same as when compiled with libssh2.
This also tries to avoid the usage of deprecated functions when the
replacements are available. The behaviour will not change if versions
older than libssh-0.8.0 are used.

Fixes#4953Closes#4962
- Allow forcing the host's key type found in the known_hosts file.
Currently, curl (with libssh2) does not take keys from your known_hosts
file into account when talking to a server. With this patch the
known_hosts file will be searched for an entry matching the hostname
and, if found, libssh2 will be told to claim this key type from the
server.
