/**
 * 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
