1. Clean up dumpcap 'as a child' err msg handling so that:
- all err msgs are properly formatted when being sent
back to the parent.
- any log Critical, Warning, etc messages
are sent back to parent and are properly formatted.
2. Change handling of -w <...> slightly in capture_opts.c
so that wireshark provides a good error message if
there is a 'write permissions' issue on the file.
(Previously the error popup said only
"Child exited with status 2").
This fixes bug #2288.
Add some conditionalized DEBUG_CHILD_DUMPCAP code for
dumpcap debug logging to a file.

In capture_sync.c: Don't clobber the DLT value.
In packet-cops.c (modified by me): Instead of adding an item as a static,
mis-cast FT_UINT16 to the tree, add it as an FT_NONE.
In packet-802.11.c: Add the right address to the tree.

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.

dumpcap, when using it as a capture child; leave the standard output
alone, in case tshark was told to write the capture to the standard
error.
Get rid of the argument to the "-Z" option to dumpcap; it might not work
on Windows.

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.

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.

transport failed between Ethereal and dumpcap.
I've also changed the way the secondary error message is transported from former "header message 0 secondary 0" to "header header message 0 header secondary 0" as that might be a bit more clearer, and I'll need it for further development anyway.
I was using this while debugging and not recognizing the real problem - for about four hours :-(. I'll need this feature when doing the interface (and link layer type) browsing later (transferring this data from dumpcap to Ethereal) to get a full blown privilege seperation.

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!).

file, strip off the last component to get the pathname of the directory
containing the executable file, and save it for future use. On Windows,
you can get that from the OS, but, on UN*X, you have to look at argv[0]
and derive the absolute path from that (argv[0] is not guaranteed to be
an absolute path, or even a path at all). (In addition, if you're
running from the build directory, you might have to strip off a ".libs/"
added to argv[0] as an artifact of the libtoolizing script.)
Use that in the About dialog, and use it to construct the path of
dumpcap.
Don't put quotes into the path of dumpcap; you don't have to quote
strings with spaces in them when handing them to execvp and, in fact,
you *mustn't* quote them, as the quotes will be treated as part of the
pathname.

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.
