a "keep reading" boolean value is returned from the function.
This avoids having to hack around the fact that some file formats truly
do have records that start at offset 0. (i4btrace and csids have no
file header. Neither does the pppdump-style file that I'm looking at right now).

Rename "union pseudo_header" to "union wtap_pseudo_header".
Make the wtap_pseudo_header pointer available in packet_info struct.

"FILE_T" is either a "gzFile" or a "FILE *", depending on whether zlib
support is enabled or not). Fix various function declarations and
definitions.

there's no need to keep it around in memory - when the frame data is
read in when handing a frame, read in the information, if any, necessary
to reconstruct the frame header, and reconstruct it. This saves some
memory.
This requires that the seek-and-read function be implemented inside
Wiretap, and that the Wiretap handle remain open even after we've
finished reading the file sequentially.
This also points out that we can't really do X.25-over-Ethernet
correctly, as we don't know where the direction (DTE->DCE or DCE->DTE)
flag is stored; it's not clear how the Ethernet type 0x0805 for X.25
Layer 3 is supposed to be handled in any case. We eliminate
X.25-over-Ethernet support (until we find out what we're supposed to
do).

and nettl captures - a "start" field is used for capture files where the
time stamps on packets are relative to some initial time stamp, e.g. the
time the capture started, but those file formats use absolute time
stamps, so no "start" field is needed.
Make the "this is an HP-UX 11.x nettl capture" flag a member of the
private data structure for a nettl capture, rather than a global - it's
per-capture-file state.
Once the "start" field is removed from the RADCOM private data
structure, there's nothing left, so eliminate the private data
structure.

from the frame table - Network Monitor 2.x, at least, doesn't always
write frame N+1 right after frame N.
To do that, we need to mallocate a big array to hold the frame table,
and free it when we close the capture file; this requires that we have
capture-file-type-specific close routines as well as
capture-file-type-specific read routines - we let it the pointer to that
routine be null if it's not needed. Given that, we might as well get
rid of the switch statement in "wtap_close()", in favor of using
capture-file-type-specific close routines, as per the comment before
that switch statement.

hideous problem on FreeBSD 3.[23] (and perhaps other BSDs) if
HAVE_UNISTD_H is defined before "zlib.h" is included, turn "file_seek()"
into a subroutine defined in a file that *undefines* HAVE_UNISTD_H
before including "zlib.h", so that the *only* call to "gzseek()" is made
from a file that does not have HAVE_UNISTD_H defined when it includes
"zlib.h".
Move "file_error()" to that file while you're at it, so it holds all the
wrappers that hide the presence or absence of zlib from routines to read
capture files.
Turn "file.h", which declared those wrapper functions as well as wrapper
macros, into "file_wrapper.h" - it belongs with the "file_wrapper.c"
file that defines the wrapper functions, not with "file.c" which handles
higher-layer file access functions.
Remove the comment in "configure.in" that explained why defining
HAVE_UNISTD_H was a bad idea, as we're not obliged to define it and work
around the problem. (The comment in "file_wrapper.c" explains the
workaround.)

Fix the error checking ("file_error()" returns an "errno" value *if*
there's an error and it's a UNIX error, but it may also return a
non-"errno" value for non-UNIX errors, so its return value should be
passed back through the "err" pointer).

more display filters for X.25;
no LCN in X.25 RESTART / DIAGNOSTIC / REGISTRATION packets;
support for nettl file format (nettl is a trace tool for HP-UX).
For now, it only supports traces for X.25 interfaces (tested
with HP-UX 10.20).
