Move LINKTYPE_WIRESHARK_UPPER_PDU definitions to a separate header. 

Have wsutil/exported_pdu_tlvs.h define the LINKTYPE_WIRESHARK_UPPER_PDU
TLV type and length values, as well as the port type values written to
files in EXP_PDU_TAG_PORT_TYPE TLVs.

Update the comment that describes the LINKTYPE_WIRESHARK_UPPER_PDU TLVs
to more completely and correctly reflect reality (it was moved from
epan/exported_pdu.h to wsutil/exported_pdu_tlvs.h).

Rename those port type values from OLD_PT_ to EXP_PDU_PT_; there is
nothing "old" about them - yes, they originally had the same numerical
values as the PT_ enum values in libwireshark, but that's no longer the
case, and the two are now defined independently.  Rename routines that
map between libwireshark PT_ values and EXP_PDU_PT_ values to remove
"old" from the name while we're at it.

Don't include epan/exported_pdu.h if we only need the
LINKTYPE_WIRESHARK_UPPER_PDU definitions - just include
wsutil/exported_pdu_tlvs.h.

In extcap/udpdump.c, include wsutil/exported_pdu_tlvs.h rather than
defining the TLV types ourselves.

version 2 bytes - xport PDU version of structure (for backwards/forwards compatibility)
seq 4 bytes - Sequence number of first byte in the data
nxtseq 4 bytes - Sequence number of first byte after data
lastackseq 4 bytes - Sequence number of last ack
is_reassembled 1 byte - Non-zero if this is reassembled data
flags 2 bytes - TCP flags
urgent_pointer 2 bytes - Urgent pointer value for the current packet
All multi-byte values are in big-endian format. There is no alignment
padding between values, so seq. nxtseq, and lastackseq are not aligned
on 4-byte boundaries, andflags and urgent_pointer are not aligned on
2-byte boundaries.
