* Split shell command line into a list of arguments and optionally execute the command(s).
* Aims to emulate \c bash and friends.
*
* - Command nesting is possible with parenthesis; for example: validateaddress(getnewaddress())
* - Arguments are delimited with whitespace or comma
* - Extra whitespace at the beginning and end and between arguments will be ignored
* - Text can be "double" or 'single' quoted
* - The backslash \c \ is used as escape character
* - Outside quotes, any character can be escaped
* - Within double quotes, only escape \c " and backslashes before a \c " or another backslash
* - Within single quotes, no escaping is possible and no special interpretation takes place
*
* @param[in] node optional node to execute command on
* @param[out] strResult stringified result from the executed command(chain)
* @param[in] strCommand Command line to split
* @param[in] fExecute set true if you want the command to be executed
* @param[out] pstrFilteredOut Command line, filtered to remove any sensitive data
