Allow sequences and hashes to be called as functions.

This is already supported in the DWIM operator.

* eval.c (apply): If object isn't a function, gather the
arguments into an array and delegate to generic_funcall.

* lib.c (generic_funcall): Changed from static to external linkage.
Supports sequences and hashes as functions. Error messages
fixed not to refer to "funcall".
(funcall, funcall1, funcall2, funcall3, funcall4): Do not throw
exception if fun is not of FUN type; instead, delegate
to generic_funcall. Error messages fixed not to refer to "funcall".

* lib.h (generic_function): Declared.
