Copyrights concerning Issue 2643 and Issue 2732 (fontforge#2735)

* bezctx_ff.c file based on bezctx_ps.c

Debian lint highlighted some copyright questions.
bezctx_ps.c from spiro-01 is GPL-2+
Patches and mods below (approx) 10 lines are listed as contributions.

* bezctx_ff.h file based on bezctx_ps.h

Original bezctx_ps.h file is uncommented but is wrapped in GPL-2+ package.
Adding authors is almost 50% of file contents, but it resolves issue 2643.

* crctab.c is practically public domain

Optimized versions using lookup tables exist in several text books,
especially when demonstrating hardware, CPUs, and C/assembler code.

* ofl.c and ofl.h created 2007-03-12

George probably didn't want to copyright name to the file, or forgot to
add it, but it's basically data files holding text information - which
can then be used to make a SIL open source license.

This patch resolves issue 2643 about author and file licence missing
when run through debian lint.

* ArabicForms.c created in 2001 - call it BSD-3-clause - issue fontforge#2643

Debian Lint highlighted some copyright questions concerning this file.
Since it's a "generated" file (created by another program), adding a
copyright notice might appear a little odd and maybe not be worth the
extra effort (when you come from a generation of programmers where
computers had very little memory or drive storage space, so you had
to put "extra" effort to save memory/storage space).
Since the project was BSD-3-clause in 2001, seems logical to imply same.
Patches and mods below (approx) 10 lines are listed as contributions.

* utype.c, utype.h created in 2001 - call it BSD-3-clause - issue fontforge#2643

Debian Lint highlighted some copyright questions concerning these files.
Since they're "generated" files (created by another program), adding a
