Fix mode-line display on TTY frames

* lisp/bindings.el (mode-line-frame-control): Remove the leading

Don’t lose subsecond info when setting mh-alias-tstamp.

Use time-convert in with-decoded-time-value

* lisp/calendar/time-date.el (with-decoded-time-value):

Simplify message-make-expires

* lisp/gnus/message.el (message-make-expires):
Use time-add instead of doing it by hand.  This also calculates the
expiration time more accurately than the old code did.

Simplify message-unique-id etc.

* lisp/gnus/message.el (message-unique-id):
* lisp/net/sasl.el (sasl-unique-id-function):
Avoid unnecessary consing and reliance on internal timestamp

no consing, instead of using (current-time) and then ignoring
the subsecond parts of the generated list.

(auto-revert-tests--write-file, auto-revert-test--wait-for):
* test/lisp/net/tramp-tests.el (tramp--test-print-duration):
Prefer nil to (current-time) when either will do, as this avoids
some consing.  Similarly, prefer omitting (current-time) arg
when this is equivalent.

Simplify cedet-utest-elapsed-time

* test/manual/cedet/cedet-utests.el (cedet-utest-elapsed-time):
Copy newer (circa-2011) implementation from elp.el, so that the

* test/lisp/calendar/time-date-tests.el (test-days-to-time)
