/* Parse a text line into words. This parsing obeys the same rules as
command line parsing but allows to skip a prefix, to use a user provided
set of separator characters, and to restrict the number of parsed words.
If parameter xorriso is NULL, then this call is safe for usage by
a concurrent thread while a xorriso API call is being executed.
@since 1.2.6
@param xorriso The context object which provides settings for parsing
and output channels for error messages.
May be NULL in order to allow concurrent execution e.g.
by a callback function of Xorriso_start_msg_watcher().
If xorriso is NULL then:
flag bit1-bit4 are in effect even if bit0 is not set.
flag bit5 and bit6 may not be set.
@param line A text of one or more words according to man xorriso
paragraph "Command processing" up to and including
"Backslash Interpretation".

Not allowed if xorriso is NULL.
@return <=0 means error and invalidity of *argv:
0 = Input format error. E.g. bad quotation mark.
-1 = Lack of resources. E.g. memory.
-2 = Improper combination of call parameters.
>0 means success but not necessarily a valid result:

be empty by argc == 0, argv == NULL).
