Paul Eggert bc511a64f6 Prefer HTTPS to FTP and HTTP in documentation
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.

# The '--check' option of git diff-index makes Git complain if changes
# introduce whitespace errors. This can be a pain when editing test
# files that deliberately contain lines with trailing whitespace.
# To work around the problem you can run a command like 'git config
# core.whitespace -trailing-space'. It may be better to revamp the
# tests so that trailing spaces are generated on the fly rather than
# being committed as source.
