Add macros for the pack_flags field.

Add macros to extract the direction, reception type, and FCS length
fields of the pack_flags field, and add definitions for different
directions and reception types.

Add a macro to construct a pack_flags field value from subfields; this
is for use by non-pcapng file readers (the pack_flags field is just a
copy of the EPB flags option, so that's not needed for pcapng).

Move some #defines for that field from packet-frame.c to wtap.h, and
rename them to match the new macros.

Use the macros rather than rolling our own code.

Fix a variable name in text2pcap.c that apparently had the wrong name,
given the value that was being tested.
