Fix deinstall of multiplexer when a default exists.
This copes with a somewhat subtle case where a default exists but the
last generator is removed. By inverting the checks, we can ensure we
only look at the cdr of the generator list when generators is actually a
pair.
The bug was originally exhibited by an error when removing the last
generator with remove-generic-procedure-generator on a generic procedure
with a default generator.

microcode (OS_test_select_registry): Check for subprocess status
changes when !blockp and the registry is empty. This is most easily
done in OS_pause, where OS_process_any_status_change (if any) is

Search the library directory path for the standard library directory
containing lib/ and the built-in object files. Adjust pathname->
standard-uri and standard-uri->pathname to use this directory instead
of the first directory in the path.
When plugins used --prepend-library to test a shared object, C worlds
failed. They could not re-load registered object files, nor load
bundled options. The guarded-system-loader only looked in the first
directory in the path, not the standard library directory.
The busy loop in the keyboard peek-no-hang operation is more expensive
than ever. Replace it with a timer in block-for-event. Cache
current-thread and check that it has not changed before deregistering.

x11-screen: Fix selection handling (cut/paste between X windows).
Cut/paste should now work with two minor fixes (typos, really), and
one kludge keeping non-unique alien objects in a weak-eq-hash-table.
The original xds (fixnums) are held as strongly as the new interned
symbols.
The xds were intended to be x-displays? Interned x-display objects
would be more appropriate keys for a weak-eq-hash-table.

x11: Fix x-display-process-events to return #f when all events read.
The plugin's version of x_display_process_events will return any
keypress even though some do not translate into any input (e.g. when
it IsModifier). X-display-process-events would return #f in that case
and preview-events think all events were read. Now x-display-process-
events returns #t and preview-events disregards it, continuing to read
events. Many callers must disregard these non-events.
Punt property-notify events in the previewer; do not queue them.

Restore interruptibility to Edwin commands when on an X display.
Commit 52eea88 (Do NOT use permanently-register-io-thread-event in
Edwin.) removed too much. Without an IO thread event registered to
preview X events, Edwin cannot be interrupted by a ^G key press.
Restore X event previewing using a custom, "permanently" registered IO
thread event that always consumes some input before re-registering
(i.e. withOUT the reading-event? variable that caused the spinning
previously). Now X events are read only in the previewer (and
wait-for-event). Keyboard operations only process queued events. And
the queue is used only by the previewer or with thread events (the
previewer) blocked.
Remove deregister-all-events from cmdl/start so that the "non-
permanent" IO thread event registered by the grab-editor wrapper is
not undone when the editor command level is started. Reversing the
order ("grab" the editor INSIDE the command level) makes the wrapper's
special operations unavailable when the command level is made. If
there is need for the aggressive decoupling of command levels as
rendered by deregister-all-events (which nevertheless did NOT remove
"permanent" IO event registrations), some mechanism will be needed to
set up the previewer after the command level is entered.

New plugins x11 and x11-screen, to replace the x11 μmodule.
The "new" code is a translation of the x11 μmodule and associated
runtime Scheme code. The C code consing Scheme objects was translated
into Scheme/FFI code parsing C data. This removed the Scheme-specific
C code except for many calls to error_external_return, which are now
error status returns. Most of the error checking is intact. All C
data structures used by Scheme are protected from leaking by "GC
cleanups".
