Patch 7.3.1248

[Bram Moolenaar]

Patch 7.3.1248
Problem: Still have old hacking code for Input Method.
Solution: Add 'imactivatefunc' and 'imstatusfunc' as a generic solution to
Input Method activation. (Yukihiro Nakadaira)

The value 0 may not work correctly with Athena and Motif with some XIM
methods. Use 'imdisable' to disable XIM then.

+ *'imstatusfunc'* *'imsf'*
+ 'imstatusfunc' 'imsf' string (default "")
+ global
+ {not in Vi}
+ {only available when compiled with |+xim| and
+ |+GUI_GTK|}
+ This option specifies a function that is called to obtain the status
+ of Input Method. It must return a positive number when IME is active.
+
+ Example: >
+ function ImStatusFunc()
+ let is_active = ...do something
+ return is_active ? 1 : 0
+ endfunction
+ set imstatusfunc=ImStatusFunc

+ NOTE: This function is invoked very often. Keep it fast.
