Fix for 77874.
In order to fix this we removed all of the Eclipse-1.0 classes
that we copied in the CDT.
The good news is that it is now part of Eclipse-3.x platform and we no
need to carry the duplicate.
The templates support was rewritten to use the JFace templates support
classes.
* src/org/eclipse/cdt/internal/corext/template/*: remove to use
JFace Templates support.
* src/org/eclipse/cdt/internal/corext/template/c/*: rewritten to use
JFace Templates classes.
* src/org/eclipse/cdt/intenal/corext/texmanipulation/*: remove to use
JFace TextEdit support
* src/org/eclipse/cdt/internal/ui/preferences/CTemplatePreferencePage.java:
Rewritten to take advantage of JFace support for Templates.
* src/org/eclipse/cdt/internal/ui/text/link/*: Remove use JFace
* src/org/eclipse/cdt/internal/ui/text/template/*: Remove use JFace templates
