Start of fallback package list implementation.
* eval.c (eval_init): Register package-fallback-list and
set-package-fallback-list intrinsics.
* lib.c (package_fallback_list, set_package_fallback_list,
intern_fallback): New functions
* lib.h (package_fallback_list, set_package_fallback_list,
intern_fallback): Declared.
* parser.y (sym_helper): Slightly restructure function
so that the symbol interning is done separately in
the various cases. In the unqualified symbol case,
use intern_fallback to search the fallback list
of the current package.
* share/txr/stdlib/package.tl (defpackage): Implement
:fallback clause.
