The following script was applied:
sed ':a;/part of MXE.$/{N;s/\n//;ba}' -i $(git grep -l 'part of MXE')
sed 's/\(part of MXE\).*\(See index.html\)/\1. \2/' -i \
$(git grep -l 'part of MXE.*See index.html')
before='This file is part of MXE. See index.html for further information.'
after='This file is part of MXE. See LICENSE.md for licensing information.'
sed "s/$before/$after/" -i $(git grep -l 'part of MXE')
Then git grep 'index.html for further information' revealed two other files.
One of them was patched manually (patch.mk). Makefile has text
"See index.html for further information" unrelated to licensing.

* many files were renamed
* file filterparserthread.h no longer include Winsock2.h
* patch "remove unused members of peerlistwidget" was removed
because peerlistwidget no longer has these members
* embeded GeoIP.dat is not needed
https://github.com/qbittorrent/qBittorrent/pull/3186
remove geoip-database from dependencies
* --with-qt4=yes (now Qt5 is the default if both present)
* patch "do not check qmake existance" was improved:
its target file has multiple equal contexts for the diff
and it was applied to wrong section; now applying to all
