; Clean up some 'require' and 'declare-function' calls in Eshell

* lisp/eshell/em-ls.el:
* lisp/eshell/esh-cmd.el:
* lisp/eshell/esh-mode.el:
* lisp/eshell/esh-ext.el: Remove superfluous 'declare-function' calls.

* lisp/eshell/esh-proc.el (pcomplete): Require this explicitly instead
of transitively.
