[PATCH setup 1/4] Use 'kill -W' when killing processes

[PATCH setup 1/4] Use 'kill -W' when killing processes

[Jon Turney]

We only have access to the Windows PID, which (since Cygwin 3.0.0) are
completely decoupled from Cygwin PIDs.

Use the new '-W' flag to indicate to kill that we are providing a
Windows PID.

(If the Cygwin install is too old to support kill -W, kill will fail,
and we'll fall back to using TerminateProcess())

[PATCH setup 2/4] Don't show FTP 550 'file not found' errors in a MessageBox

[Jon Turney]

Don't show FTP 550 'file not found' errors in a MessageBox. Also log
InternetGetLastResponseInfo() when fetching a URL.

WinInet documentation seems to indicate this kind of extended error
information only exists when WinInet has an FTP error code to report.

Log this error (and the associated URL) rather than just showing a
MessageBox. Don't bother showing a MessageBox for 550, since we can
tolerate certain missing files (e.g. setup.zst), and we'll go on to
report that couldn't fetch needed files in a more generic way.

[PATCH setup 3/4] Don't propagate actions down category tree into obsolete categories

[Jon Turney]

Choosing the 'Install' action on the 'All' category shouldn't propagate
down into the '_obsolete' category, because that will just result in
dependency conflicts due to trying to install both obsolete packages and
their replacements.

[PATCH setup 4/4] Add double-click for a 'default action' to ListView

[Jon Turney]

Add support for a double-click in the ListView to invoke a 'default
action'.

Because we receive both NM_CLICK and then NM_DBCLK, reduce the area of a
pop-up column which is sensitive to a click to the drop-down button
(which opens a focus-stealing pop-up menu), so the rest of the area can
receive a click (which does nothing) or a double-click (which does the
default action).

For a package, this default action is to toggle between the currently
installed version (or uninstalled, if not installed), and the highest
non-test version.

There is no keyboard acceleration for this action currently.
