Allow wtap_read() and wtap_seek_read() to return records other than packets.
Add a "record type" field to "struct wtap_pkthdr"; currently, it can be
REC_TYPE_PACKET, for a record containing a packet, or
REC_TYPE_FILE_TYPE_SPECIFIC, for records containing file-type-specific
data.
Modify code that reads packets to be able to handle non-packet records,
even if that just means ignoring them.
Rename some routines to indicate that they handle more than just
packets.
We don't yet have any libwiretap code that supplies records other than
REC_TYPE_PACKET or that supporting writing records other than
REC_TYPE_PACKET, or any code to support plugins for handling
REC_TYPE_FILE_TYPE_SPECIFIC records; this is just the first step for bug
8590.
