Move the declaration of split_parse_ddir(), str_split_parse() and
of the split_parse_fn typedef to thread_options.h so that
IO engines can use these functions to parse options. The definition of
struct split is also moved to thread_options.h from options.c.
The type of the split_parse_fn callback function is changed to add a
void * argument that can be used for an option parsing callback to pass
a private data pointer to the split_parse_fn function. This can be used
by an IO engine to pass a pointer to its engine specific option
structure as td->eo is not yet set when options are being parsed.
