We probably won't get files that big, but let's at least be prepared;
that squelches some compiler warnings.

In particular, epan/wslua/lrexlib.c has its own buffer_ routines,
causing some linker warnings on some platforms, as reported in bug
10332.
(Not to be backported to 1.12, as that would change the API and ABI of
libwsutil and libwiretap. We should also make the buffer_ routines in
epan/wslua/lrexlib.c static, which should also address this problem, but
the name change avoids other potential namespace collisions.)

Otherwise, if you link with both libwiretap and libfiletap, it's
anybody's guess which one you get. That means you're wasting memory
with two copies of its routines if they're identical, and means
surprising behavior if they're not (which showed up when I was debugging
a double-free crash - fixing libwiretap's buffer_free() didn't fix the
problem, because Wireshark happened to be calling libfiletap' unfixed
buffer_free()).
There's nothing *tap-specific about Buffers, anyway, so it really
belongs in wsutil.

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.

This reverts commit c0c480d08c175eed4524ea9e73ec86298f468cf4.
A better way to do this is to have the record type be part of struct wtap_pkthdr; that keeps the metadata for the record together and requires fewer API changes. That is in-progress.

This is the first step towards implementing the mechanisms requestd in
bug 8590; currently, we don't return any records other than packet
records from libwiretap, and just ignore non-packet records in the rest
of Wireshark, but this at least gets the ball rolling.

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.

which could use lseek() and were thus expensive due to system call
overhead. To avoid making a system call for every packet on a
sequential read, we maintained a data_offset field in the wtap structure
for sequential reads.
It's now a routine that just returns information from the FILE_T data
structure, so it's cheap. Use it, rather than maintaining the data_offset
field.
Readers for some file formats need to maintain file offset themselves;
have them do so in their private data structures.

by Wiretap, to indicate whether certain fields in that structure
actually have data in them.
Use the "time stamp present" flag to omit showing time stamp information
for packets (and "packets") that don't have time stamps; don't bother
working very hard to "fake" a time stamp for data files.
Use the "interface ID present" flag to omit the interface ID for packets
that don't have an interface ID.
We don't use the "captured length, separate from packet length, present"
flag to omit the captured length; that flag might be present but equal
to the packet length, and if you want to know if a packet was cut short
by a snapshot length, comparing the values would be the way to do that.
More work is needed to have wiretap/pcapng.c properly report the flags,
e.g. reporting no time stamp being present for a Simple Packet Block.

Fixed:
Crash when reading a K12text file with one frame;
Crash after selecting the last frame and then a previous frame
after file open.
Select of frame n (>1) immediately after file open incorrectly
displayed the packet details & data from frame n+1.
File ! Merge (for K12text files) did not work correctly.
Fixes:
Essentially: clear all lexer state (look-ahead buffer, etc)
for every file read. Also: Don't use global for keeping
track of the current file position.
Also: Handle *nix-style line endings as well as DOS-style.
