REORG: config: use parsing ctx for server config check

Browse Source 
Initialize the parsing context when checking server config validity.
Adjust the log messages to remove redundant config file/line and server
name. Do a similar cleaning in prepare_srv from ssl_sock as this
function is called at the same stage.

This will standardize the stderr output on startup with the parse_server
function.
