The curve25519 depends on ssh_get_random, which is normally built into libssh.
For the external override tests to build, we need to have them in separate
source file that can be included for this test.
For some reason, this did not happen on CI builds, but it did happen in koji
during RPM builds.

the XSI version of strerror_r is used. Defining
_GNU_SOURCE in torture.h then including *.c gives error
because it is assuming GNU version of strerror_r in

Fix#98 by adding 'ssh_session_set_disconnect_message' Whenever the ssh
session disconnects a "Bye Bye" message was set and displayed. Now the
peer has a choice to set a customised message to be sent after the
session is disconnected. The default "Bye Bye" will be set if this
function is not called or not called correctly. The testcases in
tests/server/torture_server can also demonstrate how this function
works.

The libssh versions before this included files with relative path based
on the current working directory, which can result unexpected results
and is different from the OpenSSH include behavior. The manual page for
ssh_config lists:
> iles without absolute paths are assumed to be in ~/.ssh if included in
> a user configuration file or /etc/ssh if included from the system
> configuration file.
This is following the semantics as close as possible with a difference
that we do not use the hardcoded ~/.ssh for user configuration files,
but the path defined with SSH_OPTIONS_SSH_DIR, which is already used
to reference any other files in used home directory.

In certificate authentication with OpenSSH 8.0, the SHA2 signatures were
not accepted correctly [1]. This was not an issue up until the OpenSSH
8.8p1, which does no longer allow SHA1 signatures by default so this
broke the CI and tests against the new OpenSSH [2].

Currently Compression=no (the default) force-disables zlib algos, while
Compression=yes force-enables it. This means that mismatching options between
client and server lead to connection failure. This can easily happen if the
server has default settings but the client specifies Compression=yes.
OpenSSH treats the option as a "prefer compression" setting:
Compression=no -> none,zlib@openssh.com,zlib (default)
Compression=yes -> zlib@openssh.com,zlib,none
This commit changes the libssh behaviour to the same as OpenSSH.

Do not compile tests which need SSHD_EXECUTABLE when

Calling some channel procedures on a freed channel is always resulting
in segmentation fault errors. The reason is that when a channel is
freed with 'ssh_channel_do_free' procedure, its 'session' field is set
to NULL; then when a channel procedure tries to access any field of
'channel->session' structure it is effectively dereferencing a NULL
pointer.
The change fixes that behavior by adding a check which ensures that a
channel state is not SSH_CHANNEL_FLAG_FREED_LOCAL before accessing its
parent session.
Also the test suite is updated to check for the fixed errors, and the
Doxygen documentation updated accordingly.
There was a bug introduced in b0fb7d15: 'ssh_channel_poll',
'ssh_channel_poll_timeout' and 'ssh_channel_get_exit_status' would
compare the channel state to the 'SSH_CHANNEL_FLAG_FREED_LOCAL'
constant to check if the channel is alive. But the procedures must
check the channel flags for the presence of
'SSH_CHANNEL_FLAG_FREED_LOCAL' bits instead. This change fixes the
bug.
