offset of the beginning of the first record containing data from that
packet, and the offset from the first byte of data in that record of the
first byte of data from that packet; to read a given packet, seek to the
offset of the first record, and keep processing packets until we find
one with the right direction.
This fixes a problem where it wasn't correctly reading the packet, when
doing random access, in cases where you have a sequence of records that
stop in the middle of a packet.

the internal z_err value for the stream if an "fseek()" call it makes
fails, so that if "gzerror()" is subsequently called, it returns Z_OK
rather than an error.
To work around this, we pass "file_seek()" an "int *err", and have the
with-zlib version of "file_seek()" check, if "gzseek()" fails, whether
the return value of "file_error()" is 0 and, if so, have it return
"errno" instead.

an "err" argument that points to an "int" into which to put an error
code if it fails.
Check for errors in one call to it, and note that we should do so in
other places.
In the "wtap_seek_read()" call in the TCP graphing code, don't overwrite
"cfile.pseudo_header", and make the buffer into which we read the data
WTAP_MAX_PACKET_SIZE bytes, as it should be.
In some of the file readers for text files, check for errors from the
"parse the record header" and "parse the hex dump" routines when reading
sequentially.
In "csids_seek_read()", fix some calls to "file_error()" to check the
error on the random stream (that being what we're reading).

For file types where we allocate private data, add "close" routines
where they were missing, to free the private data. Also fix up the code
to clean up after some errors by freeing private data where that wasn't
being done.
Get rid of unused arguments to "wtap_dump_open_finish()".
Fix indentation.

scripts, and check in changes to add _U_ to some unused arguments (some
other should perhaps be used, so we leave the _U_ out so that the
warnings serve as a reminder to check those).

The second argument to g_ptr_array_free() does not indicate to
glib to free the objects that the pointers in the GPtrArray refer to,
but simply whether or not the free the block of pointers. We have
to free the objects ourselves.

beginning of the file before reading anything from the file is bogus -
do that in the loop that tries each of the open routines, instead.
(They may have to reset the seek pointer later if, for example, the
capture file begins with the first packet, and the "open()" routine
looks at that packet to try to guess whether the packet is in the file
format in question.)
Set "wth->data_offset" to 0 while you're at it, so capture file readers
don't have to do that, either.

just an EOF, it should set "*err" to 0. Fix up a bunch of read routines
for various capture file types to set "*err" appropriately.

pseudo_header.
Use generic "p2p_phdr" instead of "lapd_phdr". Modify toshiba.c and
packet-lapd.c to take that into account.
Add frame.p2p_dir, a filterable field, 0=sent, 1=recvd
Make p2p_dir available in packe_info, as I think it will be needed
in VJ COMP and UNCOMP dissection.
Rename WTAP_ENCAP_TR to WTAP_ENCAP_TOKEN_RING.
Mention pppd-log support in man page.
Mention atmsnoop in README.
