"Applications may use the marker symbol SC_MARK_AVAILABLE to indicate
that plugins may allocate that marker number".

So AVAILABLE is specifically designed for our case, and it's Geany that
should be changed, not scintilla.

The old plugins may continue to use their fixed marker numbers, which
will show as "allocated" [1] . They won't "deallocate" the numbers on
_cleanup, but will "allocate" the same numbers if reloaded.

[1] Unless somebody uses a marker without defining it. White circle
with black background, anyone?..

A simple ui_utils function to find and return the first available
marker based on SC_MARK_AVAILABLE would suffice.
