exported PDUs. The currently opened capture file is closed.
Make sure that this does not discard any unsaved data. Ask the user for
confirmation and save the changes before running the export.

As..." code path.
Extract the code for the "do you want to overwrite this file" and "OK,
you do - are you aware it's {user-immutable, read-only}?" code paths
into a common routine for use by both of those and, potentially, other
save/export/etc. code paths in the future.
For "Save As", allow us to save atop the current capture file, as that's
just what "Save" does if there are unsaved changes, and "safe save"
makes that work. *Don't* allow that for "Export Selected Packets
As...", however.
The file chooser is run as a modal dialog, so we don't need to worry
about creating more than one of them or about the number of marked
packets etc. being changed out from under us. Get rid of a bunch of
static variables.

saving files, and run it modal (which we're already doing with the
GtkFileChooserDialog); this means less callback-based state machine
stuff, simplifying the code paths a bit.
If we're saving a file before closing it, don't bother reloading it
after saving it.

new file the current file, as is the case in most if not all other GUI
applications.
A new "Export Specified Packets" menu option allows you to specify which
packets to write out, with the default being the displayed packets (and
those on which the displayed packets depend for, e.g. reassembly), and
never makes the resulting file the current file.
The two operations are conceptually distinct. Lumping them into one
menu item, with the default for "Save As" being "displayed packets only"
and thus making it behave like the latter operation, was causing some
confusion; see, for example, bug 6640.
Make the dialog popped up if you try to "Save As" or "Export Specified
Packets" on top of an existing file ask the "do you want to do this?"
question in the main part of the message, and note in the secondary text
that doing that will overwrite what's in the file; that matches what
TextEdit on OS X and the GNOME text editor say.

so "Save" should, for non-temporary files, mean "save the current state
of the capture file on top of the existing file" without prompting for a
file name.
That means we have to do a "safe save" - i.e, write the capture out to a
new file and, if that succeeds, rename the new file on top of the old
file - as the actual packet data to write out is in the file we're
overwriting, not in memory. (We'd want to do that anyway, of
course....)
Update some comments.
Clean up indentation slightly, and get rid of an unnecessary variable
(in all the cases where we use it, we assign it the same value, and that
value isn't modified out from under us before we use it).
Note that after a "Save", or a "Save As" that writes out all captured
packets, we shouldn't have to close the current file and open the new
file and reread it - we should be able to open the new file and update
the frame offsets in the frame_data structures.
Note that we need to do some a better job of reporting rename failures.
