bug#36877: 25.3; uniquify renaway uniquify-managed list

[David Biesack]

The list uniquified-managed sometimes starts to grow in an unmanaged manner (I 
suspect exponentially) after running
Emacs for a few days. My work involves heavily editing many files named 
"openapi.yaml" in about 20 different
directories, often switching git branches so I need to revisit (M-x 
revert-buffer) these files a lot.

After a few days, I noticed opening new openapi.yaml files started to slow down 
dramatically - there would be several
seconds of delay, then tens of seconds. I narrowed this to uniquify. In my 
buffers, the local variable
uniquified-managed is more than 100,000 items long, with many duplicate items.

Here is some data (I grabbed the local variable uniquify-managed from my 
openapi.yaml buffer)

(length uniquify-managed)
100004

(cl-subseq uniquify-managed 0 19)
