This was inspired by https://code.wireshark.org/review/9729/, but takes it in a different direction where all options are put into an array, regardless of whether they are "standard" or "custom". It should be easier to add "custom" options in this design. Some, but not all blocks have been converted.
Descriptions of some of the block options have been moved from wtap.h to pcapng.h as it seems to be the one that implements the description of the blocks.
Also what could be added/refactored is registering block behavior.

If you include something from the wiretap directory, always precede it

Fix some includes of files in the top-level directory to use a path
relative to the current directory, not relative to the wiretap
directory.
This makes it a bit clearer what's being included.

g_string_free(str, FALSE) frees the GString container but not the
underlying g_malloc()ed string; instead, it returns a pointer to the
g_malloc()ed string.
Fix those places that didn't already get the string pointer from
g_string_free() to do so rather than manually extracting the string
themselves.
And fix one place that didn't even need to use a string - it was just
scanning a C string without even modifying it.

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

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

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.

There's a relatively new feature in 1.11.3 to select a specific file format
reader, instead of relying on magics or heuristics. If you select a file
reader and open a file, open it, and then click the reload-file button or go
to View->Reload or press the ctrl-R keymap, the file is reloaded but using the
magic/heuristics again instead of the file format reader you previously chose.
Likewise, the Lua relaod() function has the same issue (which is how I found
this problem).
I have tested this change by hand, using a Lua script, but I didn't add it
to the testsuite because I need another change for my test script to work
correctly. (an enhancement rather than a bug fix, which I'll submit separately)
