library/Misc_Helpers: Introduce API f_str_oct_split()

Similar to existing f_str_split() but operating on octetstrings. It uses the external f_strstr_oct() function to look up in an efficient way.

This function will be used by HTTP2 code to split multipart data based on boundary specified in the HTTP2 Header.
