a number of small compilation fixes

* ice-9/boot-9.scm: Allow a compiled load of posix, networking, and
  deprecated files.

* module/language/scheme/translate.scm (lookup-transformer): Lookup the
  sc-macro by value, not by name. Works around the fact that compiled
  macros don't have names, which is probably a bug.

* module/system/base/compile.scm (syntax-error)
  (call-with-compile-error-catch): Throw and catch a key that's not used
  by anyone else. Write error messages to the error port.

* module/system/repl/repl.scm (default-catch-handler): Call display-error
  with the correct number of arguments.

* module/system/vm/frame.scm (frame-program-name): Guard against unbound
  variables.

* ice-9/optargs.scm (let-keywords-template): Don't unquote in a helper
  procedure. A bit irritating. I suppose we should fix the modules +
  syncase situation at some point, and then switch to syncase.
