READ-BDF: A few fixes and performance improvements

A few fixes and performance improvements.
Added a parameter to help testing the apparent memory leak issue.

On Linux Mint 22.1 Cinnamon I get a filesystem protection violation error when calling WRITE-BDF-TO-MEDLEYDISPLAYFONT-FILE:

The fonts directory seems to have the right permissions:

drwxrwxr-x 4 paolo paolo   4096 Feb 25 12:18 fonts

What am I doing wrong?

What am I doing wrong?

Your {DSK}<fonts> directory corresponds to /fonts/, i.e., a root level directory. Is that actually correct?
Can you create any other file there? For example, (DRIBBLE "{DSK}<fonts>test.dribble")
WRITE-BDF-TO-MEDLEYDISPLAYFONT-FILE and MEDLEY.WRITE.FONT don't do anything special with the destination.

Do I really have {DSK}<fonts> ? Should be either {MEDLEY}/fonts/ or (MEDLEYDIR "fonts")

@pamoroso has {DSK} in the call to WRITE-BDF-TO-MEDLEYDISPLAYFONT-FILE which constructs the full path for MEDLEY.WRITE.FONT

My fonts directory is ~/il/fonts/ and I have this in my init:

(SETQ DISPLAYFONTDIRECTORIES (APPEND '(NIL "{DSK}<home>paolo>il>fonts>Commodore>" 
                                                      "{DSK}<home>paolo>il>fonts>ComicSans>" 
                                                      "{DSK}<home>paolo>il>fonts>")
                                               DISPLAYFONTDIRECTORIES))

(DRIBBLE "{DSK}<fonts>test.dribble") yields the error Protection violation: {DSK}<fonts>test.dribble;1, so it looks like I'm trying to write outside of my home directory.

At commit 8474e63 nothing unusual to report on Linux Mint 22.1 Cinnamon.
