Move the toolkit-independent code to create a temporary capture file,
and to fork off and run a separate copy of "ethereal" for "-S" and "-F"
captures or just call "capture()" otherwise, out of "gtk/capture_dlg.c"
and into a routine in "capture.c".
If the attempt to create said temporary capture file fails, pop up a
dialog box and don't do the capture.
Have the child capture process send a message upstream after it either
successfully starts the capture and syncs out the header of the capture
file, or fails to start the capture; the message indicates whether it
succeeded or failed, and, if it failed, includes a failure message.
This:
avoids the use of a signal, and thus means we don't have to
worry about whether to capture the signal, or whether to start
or stop capturing depending on whether this particular capture
is in sync mode or not;
lets us pop up the message box for the error in the parent
process if we're in sync mode, rather than doing it in the
child, which didn't work well.
Add a check button to the Capture/Start dialog box, so that we can
control, for each capture, whether it's to be done in sync mode or not.

Have the child capture process send a message upstream after it either
successfully starts the capture and syncs out the header of the capture

succeeded or failed, and, if it failed, includes a failure message.
This:
avoids the use of a signal, and thus means we don't have to
worry about whether to capture the signal, or whether to start
or stop capturing depending on whether this particular capture
is in sync mode or not;
lets us pop up the message box for the error in the parent
process if we're in sync mode, rather than doing it in the
child, which didn't work well.
Add a check button to the Capture/Start dialog box, so that we can
control, for each capture, whether it's to be done in sync mode or not.
