Use a safe tailq traversal for FSEVENT/PROCEVENT-type EventSink callbacks.

This allows callbacks to use AG_DelEventSink() on the EventSink itself.

To help detect double-frees, trash the tag/name/cls in ObjectDestroy().

Add validity tests to AG_ObjectAttach() and AG_ObjectDetach().

Remove "sender" as mandatory argument of AG_PostEvent(), make senders "normal" arguments.

Introduce the SENDER variable flag. This prevents lots of unnecessary NULL-pointer passing,
improves event-delivery performance and liberates a slot in argv[].

Deprecate the Event flags ASYNC and PROPAGATE. Both can be implemented easily without the use
of such magic (and with greater flexibility as to where the recursion happens in the case
of PROPAGATE). Bump EVENT_NAME_MAX back to 24 now that AG_Event doesn't require flags anymore.
[TODO: LEGACY shims]

Add the --disable-widgets option to build Agar without any built-in Widgets.

Add --disable-wm-hints to produce a build without any WM-specific hints (useful for
debugging WM-hint-related issues).

Get rid of the agTextState pointer. It is safer to index agTextStateStack[].

Supply an accessor macro AG_TEXT_STATE_CUR() to obtain the current state (and perform
validity checks in debug mode).

Make the AG_PopTextState() assertion paranoid.

Perform a single memcpy() in AG_PushTextState(), overwriting "font" only.

Various small optimizations. Remove unnecessary locks in AG_TextFont(), etc. since those
calls only make sense in rendering, sizing or event-handling context.
