657d9143d1 SSH_LOG_DEBUG: Recategorize loglevels
Loglevel INFO is the default openssh configuration setting which does not print
redundant information. On a system using openssh with loglevels set by the
terms of openssh will cause unwanted log lines in the output.
recategorized based on - SSH_LOG_DEBUG are informational debug logs (no error)

7ea75cda45 SSH_LOG_TRACE: Recategorize loglevels
Do not print out logs when no fatal error happens.
This approach is similiar to openssh, when Error/Fatal does not print
recoverable error logs.

51a53cc6d4 add support for identityagent ssh_config option
This commit adds an `agent_socket` field to the session options
and connects the config parser to that option.

`SSH_OPTIONS_IDENTITY_AGENT` is added to allow applications to
set this option for themselves.

agent.c is updated to take the `agent_socket` value in preference
to the `SSH_AUTH_SOCK` environment variable.

899ec9e519 Enable ssh agent authentication on Windows
Windows has supported unix domain sockets for a couple of years
now; see this article for more information about that:
<https://devblogs.microsoft.com/commandline/af_unix-comes-to-windows/>

This commit allows libssh to consider using agent authentication
on Windows systems.

It is mostly removing `#ifndef _WIN32` that prevented the unix
domain socket code from being compiled in, and adjusting the use
of `read(2)` and `write(2)` to `recv(2)` and `send(2)`, as the former
functions are not compatible with sockets on Windows systems.

For mingw systems, afunix.h isn't available so we use the
technique as was used to resolve building with mingw as used
by the curl project in: https://github.com/curl/curl/pull/5170

132ed59d3f agent: Use SHA2 signatures also for RSA certificates
There is actually a bug in OpenSSH's ssh-agent of handling these
requests [1], but this change follows the way how OpenSSH clients
behave in regards to the communication with agent.

Without this change, the agent is asked to provide SHA1 signature
with certificates, which is not right if we negotiated SHA2 extensions.

Add a small helper for ssh_buffer to ensure that the buffer has a
certain amount of space already preallocated. This can be useful in case
it is known how much data is going to be added to a buffer, to avoid
multiple reallocations.

Make use of it in few places in the library.
