in some places use "guint64", on plaforms where it's available,
rather than floating point (we don't yet use it universally, as
we'd have to provide code to do 64-bit arithmetic on
platforms/compilers where 64-bit integral types aren't
supported);
use .838096 microseconds rather than 1 microseconds as the time
stamp units for NetXRay 2.x format, as those capture files seem
to use that time stamp (that's the Sniffer "PC" time stamp;
perhaps when Network Associates assimilated Cinco, they changed
the time stamp units).

don't need to work around that.
The offset, for a given packet, at which "ascend_seek()" should start
searching for that packet's header must be computed separately from the
offset, for that packet, at which "ascend_seek()" should start searching
for the *next* packet - if the file is a "wdd" capture, and the packet
has a "Date:" header and a WD_DIALOUT_DISP header, the search for that
packet should start at the beginning of the "Date:" header, but the
search for the next packet should start after the WD_DIALOUT_DISP
header, as if we start it after the "Date:" header, the search will stop
at the packet's own WD_DIALOUT_DISP header, as a packet could have a
WD_DIALOUT_DISP header but no "Date:" header.

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).

every C file. I noticed this because of a build break of csids.obj on
Win32.

- add <stdarg.h> or <varargs.h> in snprintf.h
and remove those inclusions in the other #ifdef NEED_SNPRINTF_H codes
- remove the check of multiple inclusions in source (.c) code
(there is a bit loss of _cpp_ performance, but I prefer the gain of
code reading and maintenance; and nowadays, disk caches and VM are
correctly optimized ;-).
- protect all (well almost) header files against multiple inclusions
- add header (i.e. GPL license) in some include files
- reorganize a bit the way header files are included:
First:
#include <system_include_files>
#include <external_package_include_files (e.g. gtk, glib etc.)>
Then
#include "ethereal_include_files"
with the correct HAVE_XXX or NEED_XXX protections.
- add some HAVE_XXX checks before including some system header files
- add the same HAVE_XXX in wiretap as in ethereal
Please forgive me, if I break something (I've only compiled and regression
tested on Linux).

sequential pass through the file build a list of information about the
compressed blobs, with the starting offset in the compressed file and in
the uncompressed byte stream for each blob.
When seeking on the random stream, check whether the target location is
within the uncompressed buffer we currently have; if not, use that list
to figure out which blob contains the target location, and read that
blob into the buffer. Then, as we now know that the target location is
within the uncompressed buffer we currently have, just move the current
pointer into that buffer to the target location.
This means we don't have to read forwards through any uninteresting
blobs in order to seek forwards, and don't have to go all the way back
to the beginning and seek forwards in order to seek backwards.

is finally dead, and you're walking away, it springs up again and
attacks.
It appears that the ss990915 version of Alexey Kuznetzov's libpcap patch
has some extra stuff in the per-packet header for some sort of SMP
debugging, and that SuSE Linux 6.3 picked it up.
Thus, even if a libpcap file has the modified magic number, we *still*
have to go through the usual heuristic hell to figure out what type of
file it is.

to that file, leave public definitions in wtap.h.
Rename "union pseudo_header" to "union wtap_pseudo_header".
Make the wtap_pseudo_header pointer available in packet_info struct.
