errors, have it send a sync-pipe "success" message on success, and have
the callers get that message and display it.

monitor mode at the same time that we fetch its list of link-layer
types. Support fetching that list in monitor mode, as the list may be
different in regular and monitor mode. If the interface supports
monitor mode, when printing the list of link-layer types, indicate
whether they're fetched in monitor mode or not, as tcpdump 4.1.x does.

does capturing any more. (We will be inserting a call to give up
privileges after the pcap_open_live(), which should fix 2273; we're
currently only giving up privileges on platforms with libcap.)

pipe instead of stdin. Add an argument (currently the parent PID) back
to the "-Z" flag and use it to construct the pipe name. This lets us
pass the parent's stdin handle to dumpcap, which lets us capture from
stdin on Windows. Add a comment about checking for the parent process.
In capture_loop.c, remove the wait_forever argument from cap_pipe_select()
since it was always FALSE. Set the timeout under Windows to 250 ms
instead of 250000 ms.

of the last pcap_open_live() call in the GUI code. Update
README.packaging.

that "-D" and "-L" should produce machine-readable output. Use this to
move an indirect get_pcap_linktype() call from the GUI to dumpcap.

Add a capture_interface_list(), which works similar to
get_interface_list() except that it forks dumpcap instead of calling
the pcap routines directly. Use it in the GUI.
Add a "-I" flag to dumpcap, which prints out verbose interface
information.
Tested under Windows and Linux.

by dumpcap and Ethereal (so that, on UN*X, the child process can report
a detailed "can't exec dumpcap" error).
Rename most of the "sync_pipe_XXX_to_parent()" routines, as they're also
in Tethereal, which doesn't have a sync pipe.

primary and secondary error messages and let the parent worry about how
to display them. This means dumpcap doesn't need stub routines for
generating the formatting tags for the primary and secondary messages.
Have a separate message for capture filter errors, so that the parent
can check whether the capture filter looks like a display filter and
report the appropriate message. This means that dumpcap doesn't need a
stub routine for compiling display filters (a stub routine also means
that Ethereal won't do the check for capture filters that look like
display filters!).

using dumpcap as the capture child for Ethereal.
dumpcap is a plain console application now, even for Win32 (so no WinMain, create_console and special piping stuff reguired). The undocumented command line option -Z will switch dumpcap into "child mode", using binary instead of plain text output messages to communicate with a parent Ethereal.
Ethereal's main.c no longer needs to distinguish between child mode or not, so some simplifying here.
capture_sync.c has to call dumpcap in a "hidden window" mode using CreateProcess instead of spawnvp, otherwise an uggly console window would appear. The handles created by _pipe doesn't seem to be inheritable for this function, using CreatePipe instead.
The file capture_loop.c is only needed by dumpcap, removed from Ethereal link objects.
Some debugging aid added and other minor cleanup done.

This way, the capture child don't need to now any of the packet_counter things (no epan/packet.h and all alike).
Currently the capture_info code will always open another wiretap file instance to build it's own counter values. This isn't optimized for now (next step: use data from cf_continue_tail() somehow).

add a new feature to clear the currently captured packets and restart the capture with the previous parameters
various code cleanup and minor bugfixes
Win32: use millisecond resolution in capture_loop, to smooth screen update a bit (500ms instead of 1000ms)
svn path=/trunk/; revision=14059
display filename in statusbar while capturing
print_usage banner fixed
cf_cb_live_capture_prepare no longer needed
rename sync_pipe_do_capture -> sync_pipe_start
bugfix: sync_pipe_input_wait_for_start replaced by former implementation
fix cleanup of old file in capture_input_new_file
fix a tempfile detection bug (named file showed up as tempfile after capture)
svn path=/trunk/; revision=14053
don't use global cfile at all but only an untpyed handle to call the cf_... functions in file.c
move the save_file member from capture_file to capture_opts, as it's only used while capturing and while preparing it
svn path=/trunk/; revision=13276
Hopefully the unspecified forward declaration of capture_options_t in main.h is portable, but buildbot will tell me. This way I need the internals of that struct only at the places I really use it.
