dfilter: add string() function.
This function can convert non-string fields into strings. This allows the
user to apply string functions (like contains and matches) to non-string fields.
Examples:
string(frame.number) matches "[13579]$" => for odd frames
string(eth.dst) matches "aa\.bb\.cc\.dd\.ee\..." => to match a group of stations
string(snmp.name) matches "^1.2.3.4" => for all OIDs under a specific node
