Chris Hanson [Sun, 14 Oct 2018 02:54:58 +0000 (19:54 -0700)]
Extensive work to get compiler to work with R7RS libraries.
The bulk of the work is to refactor the debugging info so that it's generated
and consumed properly; this required upgrading the version and introducing a new
top-level info form.
I also eliminated the now-ancient and unused BSM file support, which was making
things more difficult than necessary.
The compiler top level required only to detect an R7RS input file and to compile
each part separately, plus collecting all of the debugging information from the
parts. Some tweaks were used to make RTL/LAP files work right with multiple
roots.
Finally, the runtime system was modified so that compiled-code blocks and
entries now show the R7RS library name if there is one, both when printed and in
various other places.

Fix bug: reference caches weren't working right without global env.
The problem arises when there's a compiled file that does something like this:
(define foo ...)
...
foo
What happens is that the linker creates a cache for 'foo' before evaluating
code; there's no binding for 'foo' yet but one is needed for the cache. In the
case where the evaluation environment extends to the global environment, this is
handled by making a placeholder in the global environment.
However, if the topmost frame is not the global environment, it was creating a
dummy cell that wasn't connected to any environment. Consequently, when the
definition was evaluated, it created a new binding, but since there was no old
binding in the environment chain, the dummy cache wasn't updated to the new
binding's cell.
I've fixed this by forcing the creation of an unbound cell in the outermost
environment (i.e. the one with the null environment as its parent). This is
essentially the same solution that's used when the global environment is
present, with the outermost environment playing the role of global.
