Guy Harris 6e6233521a Have WTAP_ERR_INTERNAL include an err_info string giving details.
That way, users won't just see "You got an internal error", the details
will be given, so they can report them in a bug.

Guy Harris e63a3f5d81 Don't use <wtap.h> to refer to the main libwiretap header file.
Either use "wtap.h", if it's only for files in the wiretap directory, or
<wiretap/wtap.h>, if it's also a header that stuff outside libwiretap
can include.

Guy Harris a1b1c8bed5 Revert "Refactor Wiretap"
This reverts commit 1abeb277f5.

This isn't building, and looks as if it requires significant work to fix.

Michael Mann 1abeb277f5 Refactor Wiretap
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.

Guy Harris 2b8ebd389b "This file format can't be written to a pipe" and "this file format
can't be saved in compress form" are both equivalent to "this file file
format requires seeking when writing it".  Change the "can compress"
Boolean in the file format table to "writing requires seeking", give all
the entries the proper value, and do the checks for attempting to write
a file format to a pipe or write it in compressed format to common code.

This means we don't need to pass the "can't seek" flag to the dump open
routines.

Guy Harris 8a8b883450 Set the svn:eol-style property on all text files to "native", so that
they have LF at the end of the line on UN*X and CR/LF on Windows;
hopefully this means that if a CR/LF version is checked in on Windows,
the CRs will be stripped so that they show up only when checked out on
Windows, not on UN*X.

Guy Harris d6cd61061e Have the Wiretap open, read, and seek-and-read routines return, in
addition to an error code, an error info string, for
WTAP_ERR_UNSUPPORTED, WTAP_ERR_UNSUPPORTED_ENCAP, and
WTAP_ERR_BAD_RECORD errors.  Replace the error messages logged with
"g_message()" for those errors with g_strdup()ed or g_strdup_printf()ed
strings returned as the error info string, and change the callers of
those routines to, for those errors, put the info string into the
printed message or alert box for the error.

Add messages for cases where those errors were returned without printing
an additional message.

Nobody uses the error code from "cf_read()" - "cf_read()" puts up the
alert box itself for failures; get rid of the error code, so it just
returns a success/failure indication.

Rename "file_read_error_message()" to "cf_read_error_message()", as it
handles read errors from Wiretap, and have it take an error info string
as an argument.  (That handles a lot of the work of putting the info
string into the error message.)

Make some variables in "ascend-grammar.y" static.

Check the return value of "erf_read_header()" in "erf_seek_read()".

Get rid of an unused #define in "i4btrace.c".

Guy Harris 44d19627ef From Graeme Hewson:
Allow "-" as the output file name in Wiretap, referring to the
	standard error.

	Optimize the capture loop.

Fix some of the error-message printing code in Ethereal and Tethereal.

Have Wiretap check whether it can seek on a file descriptor, and pass
the results of that test to the file-type-specific "open for output"
routine.  Have the "open for output" routines for files where we need to
seek when writing the file return an error if seeks don't work.

Laurent Deniel 6a480953a9 Miscellaneous code cleaning
- 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).

Guy Harris aae22bd227 Have the per-capture-file-type open routines "wtap_open_offline()" calls
return 1 on success, -1 if they got an error, and 0 if the file isn't of
the type that file is checking for, and supply an error code if they
return -1; have "wtap_open_offline()" use that error code.  Also, have
the per-capture-file-type open routines treat errors accessing the file
as errors, and return -1, rather than just returning 0 so that we try
another file type.

Have the per-capture-file-type read routines "wtap_loop()" calls return
-1 and supply an error code on error (and not, as they did in some
cases, call "g_error()" and abort), and have "wtap_loop()", if the read
routine returned an error, return FALSE (and pass an error-code-pointer
argument onto the read routines, so they fill it in), and return TRUE on
success.

Add some new error codes for them to return.

Now that "wtap_loop()" can return a success/failure indication and an
error code, in "read_cap_file()" put up a message box if we get an error
reading the file, and return the error code.

Handle the additional errors we can get when opening a capture file.

If the attempt to open a capture file succeeds, but the attempt to read
it fails, don't treat that as a complete failure - we may have managed
to read some of the capture file, and we should display what we managed
to read.

Gilbert Ramirez fcb4c78a6a A lengthy patch to add the wiretap library. Wiretap is not used by default
because it is still in its infancy, but it can be compiled in optionally.
The library exists in its own subdirectory ethereal/wiretap. This patch also
edits all the packet-*.c files to remove the #include <pcap.h> line which is
unnecessary in these files. In the ethereal code, file.c is the most heavily
modified with #ifdef WITH_WIRETAP lines for the optional library.
