Remove config options: protocol, mac, cipher, compressionlevel,
gssapikeyexchange,
gssapirenewalforcesrekey,
gssapitrustdns,
rhostsrsaauthentication,
rsaauthentication,
useprivilegedport,
pubkeyacceptedtypes
since they are not supported by OpenSSH
Rename some config options:
hostbasedkeytypes, challengeresponseauthentication and pubkeyacceptedkeytypes
to hosbasedacceptedalgorithms, kdbinteractiveauthentication and pubkeyacceptedalgorithms
to be consistent with the OpenSSH manual https://man.openbsd.org/sshd_config.
Keep pubkeyacceptedkeytypes for backward compatibility.
Rename SOC_PUBKEYACCEPTEDTYPES to SOC_PUBKEYACCEPTEDKEYTYPES in config.h
Update unittests/torture_config.c and unittests/torture_options.c

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.

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.

This allows the global client (ssh_session) configuration file path to
be set in configuration time by defining GLOBAL_CLIENT_CONFIG when
calling cmake. If it is not defined, the default path is set as
"/etc/ssh/ssh_config".
usage example:
$ cmake -DGLOBAL_CLIENT_CONFIG=/etc/my/custom/path ..

This adds the OpenSSH HMACs that do encrypt then mac. This is a more
secure mode than the original HMAC. Newer AEAD ciphers like chacha20 and
AES-GCM are already encrypt-then-mac, but this also adds it for older
legacy clients that don't support those ciphers yet.

* This makes the array constant in the session structure, avoiding
allocations and frees while parsing the file
* It also drops passing the seen array to all the functions,
because it is already part of the passed session
* The test cases are adjusted to match these changes
