/* Given TOK, a string possibly containing a condition, thread, inferior,
task and force-condition flag, as accepted by the 'break' command,
extract the condition string, thread, inferior, task number, and the
force_condition flag, then set *COND_STRING, *THREAD, *INFERIOR, *TASK,
and *FORCE.
As TOK is parsed, if an unknown keyword is encountered before the 'if'
keyword then everything starting from the unknown keyword is placed into
*REST.
Both *COND and *REST are initialized to nullptr. If no 'if' keyword is
found then *COND will be returned as nullptr. If no unknown content is
found then *REST is returned as nullptr.
If no thread is found, *THREAD is set to -1. If no inferior is found,
*INFERIOR is set to -1. If no task is found, *TASK is set to -1. If
the -force-condition flag is not found then *FORCE is set to false.
Due to the free-form nature that the string TOK might take (a 'thread'
keyword can appear before or after an 'if' condition) then we end up
having to check for keywords from both the start of TOK and the end of
TOK.
If TOK is nullptr, or TOK is the empty string, then the output variables
are all given their default values. */
