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.

### Commentary:
## Generate info/dir, for systems without install-info.
## Expects to be called from top-level Emacs source directory.
## It only handles the case where info/dir is missing from the
## installation directory. It does not handle info/dir being present
## but missing some entries.
## Header contains non-printing characters, so this is more
## reliable than using awk.
