Added Class/Base infrastructure to public interfaces & requestor callback.
Moved many internal interfaces to external packages.
Organized imports.
Fix for PR 38788: Ctrl-X, Ctrl-C, Ctrl-V, Ctrl-A, Ctrl-Z and Ctrl-Y keys don't work in the address field of the Memory view.
Note: Ctrl-Z still doesn't work because there is no support of it in the Text widget.
