Have two different classes of file-type-specific records - "events" and
"reports". An "event" indicates something that happened in the capture
process, such as a status transition on the network; a "report" just
gives information not corresponding to something happening in the
capture process, such as capture statistics.
Note that both of those should be dissected and displayed like packets,
and leave open the possibility of file-type-specific records whose
contents should be processed and saved but not displayed in the packet
list.
Shorten "file_type_specific" to "ft_specific".

We rename "file format" plugins to "libwiretap" plugins, as they can
register as read handlers for a new file type, read/write handlers for a
pcap-ng block type (or both).
To register as a pcap-ng block type handler, in the
register_wtap_module() routine of your plugin, call
register_pcapng_block_type_handler() with the pcap-ng block type and
pointers to your routines to read and write those blocks. Those
routines should read and write REC_TYPE_FILE_TYPE_SPECIFIC records, with
the block type in the pseudo-header for the record in the struct
wtap_pkthdr structure, with time stamps stored in that structure, and
with a blob of data for the rest of the record.
This is for bug 8590.

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.

While investigating an ASAN issue (fixed in
commit dcdd076ab0), I got greatly confused
by three different types having the same "interface_data" field name:
* pcapng_t *pn stores an array of interface_data_t objects.
* wtap *wth stores an array of wtapng_if_descr_t objects.
* pcapng_dump_t should store an array of interface_data_t objects.
pcapng_dump_t and friends are unused since
commit c7f1a431d2, so drop it.
To fix the confusion, rename the interface_data_t type to
interface_info_t type and use the local variable "iface_info"
everywhere. Rename interface_data of pcapng_t to "interfaces" and
add a comment what this exactly means (interfaces listed in the capture
file).
Drop the number_of_interfaces field for interfaces as the array
length is already available from GArray. Now interface_data is always
initialized for wth (which also gets copied to idb).
s/int/guint/g and replace cast at some places.
There are no regressions for the in-tree test suite.

Start of refactoring Wiretap and breaking structures down into "generally useful fields for dissection" and "capture specific". Since this in intended as a "base" for Wiretap and Filetap, the "wft" prefix is used for "common" functionality.
The "architectural" changes can be found in cfile.h, wtap.h, wtap-int.h and (new file) wftap-int.h. Most of the other (painstaking) changes were really just the result of compiling those new architecture changes.
