Instead of always setting the libssh log level to SSH_LOG_INFO
when an extcap has a ws log level of LOG_LEVEL_DEBUG or lower,
set the libssh log level to a corresponding log level
(NOISY/TRACE, DEBUG/DEBUG, INFO/INFO, MESSAGE and above/WARN).
Format the libssh logging messages more similar to our normal
logging messages, with a libssh domain and using the libssh
priority.
Prior to 0.11.0 (that is, this commit:
657d9143d1
) libssh sends some merely informational messages at their WARN
level, so lower that down to INFO, which isn't printed by default
and doesn't get printed in the GUI.
