b638b9f1b4 Hygiene change. Removing syntactic closure flattening to 
support unhygienic insertion.  Breaks the previous assumption
that syntactic closures were never nested.

156505e798 The environment chain lookup should ignore undefined cells if there 
are defined cells available.  This avoids previously undefined values
blocking an export-all import.

7a5f317811 Fixing bug in the non-strict top-level identifier matching logic. 
Matching worked when both bindings were missing, and when both
bindings were present at the top-level but different.  The case
when only one top-level binding was present wasn't handled correctly.
Local lexical matching remains unchanged.
Fixes issue #198.

d85cff247e Fixing bug when using -x with a language which doesn't have 
interaction-environment.  We need to set this in the underlying
core environment first.  Fixes issue #193.

83fb186edc Wrapping continuable exceptions in specially tagged exceptions rather than pairs. 
This way C functions that check for and print exceptions support them
automatically.  Notably continuable errors in macro expansions, will had
temporarily been suppressed, are printed again.

d6b6ce955b Differentiating between analyze_app and the new analyze_list. 
The latter is just for any list of ASTs to analyze, whereas the former
checks for lambda applications and fills in names.  Fixes equality
comparisons for procedures, so (equal? (lambda (x) x) (lambda (y) y))
now returns true.

83f8cfd69b Adding note about the derived syntax definition of quote. It makes 
compilation slightly but noticeably slower and is inconvenient, so
leaving as a core form for now.

6de7d5621d Keeping track of the maximum stack depth a procedure needs for accurate stack checks 
(fixes bug #130).  Done in conjunction with code generation refactoring, so that context
objects temporarily use their specific slot instead of having space for useful fields
at runtime.
