bug#13795: 24.3.50; epa-insert-keys improvements

[Richard Stallman]

epa-insert-keys is slow to start.  If I use it multiple times
in a row, it is slow each time.

It should check whether the keyring has changed since the previous
call to epa-insert-keys.  If not, it should use the same buffer
contents.

The slowness is surprising -- maybe it can be sped up.
