Bug 1448876 - Get rid of nsIClipboardDragDropHooks and nsIClipboardDragDropHookList interfaces r=bz nsIClipboardDragDropHooks and nsIClipboardDragDropHookList allow XUL apps to customize drag and drop operation and paste operation. However, this feature was used only by ChatZilla and it doesn't work on Gecko anymore. So, we can get rid of them from our tree. MozReview-Commit-ID: Ibs3V1gI8Ry

# Generate SOURCES in sources.mozbuild files from ICU's Makefile.in
# files, and also build a standalone copy of ICU using its build
# system to generate a new copy of the in-tree ICU data file.
#
# This script expects to be run from `update-icu.sh` after the in-tree
# copy of ICU has been updated.
