> The cmdline library cmdline_parse() function parses a command and
> executes the action automatically too. The cmdline_valid_buffer function
> also uses this function to validate commands, meaning that there is no
> function to validate a command as ok without executing it.
> 
> To fix this omission, we extract the body of cmdline_parse into a new static
> inline function with an extra parameter to indicate whether the action should
> be performed or not. Then we create two wrappers around that - a
> replacement for the existing cmdline_parse function where the extra
> parameter is "true" to execute the command, and a new function
> "cmdline_parse_check" which passes the parameter as "false" to perform
> cmdline validation only.
