(semantic-lex-test-full-depth):
Use nil instead of (current-time) where either will do, as nil is
a bit more efficient and should have less timing error.

Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November.  Change these FTP URLs to https://ftp.gnu.org
instead.  Make similar changes for URLs to other organizations moving
away from FTP.  Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.

Not all the cases where we had string-as-unibyte were characters,
so this needs to be considered more thoroughly before being redone.

The commit somehow lead to problems in other parts of Emacs.

* lisp/gnus/gnus-art.el (gnus-article-mode-map): Also bind the
C-c keys so that they execute in the summary buffer
(bug#18257).  This makes commands like `C-c C-f' work from the
article buffer.
