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.

c052c904ff Remove no-byte-compile setting from some lisp/language files. 
Same comments as per 2012-05-01T06:59:34Z!rgm@gnu.org, for lisp/term:

  Not that compiling these will bring any noticeable speed benefit, but
  there's really no reason not to compile them.  The extra disk space
  and build time is negligible, and it might reveal use of obsolete
  functions, bugs, etc.
