really boot primitive-eval from scheme.

* libguile/eval.c (scm_primitive_eval, scm_c_primitive_eval):
  (scm_init_eval): Rework so that scm_primitive_eval always calls out to
  the primitive-eval variable. The previous definition is the default
  value, which is probably overridden by scm_init_eval_in_scheme.

* libguile/init.c (scm_i_init_guile): Move ports and load-path up, so we
  can debug when initing eval. Call scm_init_eval_in_scheme. Awesome.

* libguile/load.h:
* libguile/load.c (scm_init_eval_in_scheme): New procedure, loads up
  ice-9/eval.scm to replace the primitive-eval definition, if everything
  is there and up-to-date.

* libguile/modules.c (scm_module_transformer): Export to Scheme, so it's
  there for eval.go.

* module/ice-9/boot-9.scm: No need to define module-transformer.

* module/ice-9/eval.scm (capture-env): Only reference the-root-module if
  modules are booted.
  (primitive-eval): Inline a definition for identity. Throw a more
  standard error for "wrong number of arguments".

* module/ice-9/psyntax.scm (chi-install-global): The macro binding for a
  syncase macro is now a pair: the transformer, and the module that was
  current when the transformer was installed. The latter is used for
  hygiene purposes, replacing the use of procedure-module, which didn't
  work with the interpreter's shared-code closures.
  (chi-macro): Adapt for the binding being a pair, and get the hygiene
  from the cdr.
  (eval-local-transformer): Adapt to new form of macro bindings.

* module/ice-9/psyntax-pp.scm: Regenerated.

* .gitignore: Ignore eval.go.stamp.

* module/Makefile.am: Reorder for fastest serial compilation, now that
  there are no ordering constraints. I did a number of experiments here
  and this seems to be the best; but the bulk of the time is compiling
  psyntax-pp.scm with eval.scm. Not so great.

* libguile/vm-engine.c (vm-engine): Throw a more standard error for
  "wrong type to apply".

* test-suite/tests/gc.test ("gc"): Remove a hack that shouldn't affect
  the new evaluator, and throw in another (gc) for good measure.

* test-suite/tests/goops.test ("defining classes"):
* test-suite/tests/hooks.test (proc1): We can't currently check what the
  arity is of a closure made by eval.scm -- or more accurately all
  closures have 0 required args and no rest args. So punt for now.

* test-suite/tests/syntax.test ("letrec"): The scheme evaluator can't
  check that a variable is unbound, currently; perhaps the full "fixing
  letrec" expansion could fix this. But barring that, punt.
