Guy Harris 0cc75a3569 In Wiretap, a file stream handle is a "FILE_T", not a "FILE_T *" (a
"FILE_T" is either a "gzFile" or a "FILE *", depending on whether zlib
support is enabled or not).  Fix various function declarations and
definitions.

Guy Harris f3d90d30a4 Remove the "union pseudo_header" from the "frame_data" structure;
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).

Guy Harris d51f36236f Get rid of the "start" field in the private data for RADCOM, i4btrace,
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.

Guy Harris 7a36bede0b We are obliged to define HAVE_UNISTD_H in "config.h"; to avoid the
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.)

Guy Harris 9658c33db6 Handle i4btrace captures if they're from a machine with the opposite
byte order from the machine that's reading them.
