misc: Add `find_delm()`, and `get_str_delm_range()`

`find_delm()` finds the first matched delimiter of the supplied
delimiter(s), and either returns the pointer to the first non-delimiter
character after the match, or the match itself if `skip_delm` is true,
or false respectivly.

`get_str_delm_range()` finds, and returns the string in between the
supplied starting, and ending delimiter(s). It also returns the pointer
to the first non-delimiter character after the end of the range in
`rhs`.
