(Qto_decomposition_at_compat): New variable.

(Q_compat_of): Renamed from `Q_compatibility_of'.
(put_char_composition): Rename `Q_compatibility_of' to `Q_compat_of';
return `=>decomposition@compat' for compatibility decomposition mapping.
(Fsave_char_attribute_table): Rename `Q_compatibility_of' to
`Q_compat_of'.
(syms_of_chartab): Add new symbol `=>decomposition@compat'; rename
`<-compatibility' to `<-compat'.
