[PATCH v3 05/15] ref-filter: introduce parsing functions for each valid atom

[Karthik Nayak <karthik.188@gmail.com>]

Parsing atoms is done in populate_value(), this is repetitive and
hence expensive. Introduce a parsing function which would let us parse
atoms beforehand and store the required details into the 'used_atom'
structure for further usage.
