[Fontforge-devel] aarch64 support for autotools

aarch64 is going to arrive later this year, and support for configuring
and building on it landed in autoconf 2.69. Currently fontforge has an
older version of autoconf used.

Graphical flowchart for build environment shown here:

check consistency of glyph counts on input and output, and document it
prevent RemoveUnused from removing slots that the encoding requires

If you want to do that, you should re-encode first.  Note that it already
wouldn't remove any slots before the last used slot, so it's clear that this
command would never have been able to *really* remove all unused slots in
encodings that required them to remain.  Its intended use seems to have been
for removing unused unencoded slots at the end.
tighten up some boundary cases
Don’t rename glyphs one didn’t ask for from Python

SFGlyphRenameFixup() is too smart that it will, when renaming “f”, it
will search for glyphs that has an “f” component, e.g. “f_f” or “f_f_i”
and rename the component as well. The desirability of this is
questionable, but for now I added a boolean flag to control this and
disable it in Python while keeping the GUI behaviour unchanged.

Don’t rename glyphs one didn’t ask for from Python (note ..else forget)

These things can get forgotten later - better highlight a note.
