[Ecls-list] Latest changes

[Juan Jose Garcia-Ripoll]

* Visible changes:

 - FFI:CLINES is no longer restricted to appear as a toplevel form. The
   following code is thus valid:
        (defun c-sin (x)
          (ffi:clines "#include <math.h>")
          (ffi:c-inline (x) (:double) :double "sin(#0)" :one-liner t))

 - Function ecl_stream_to_handle() now exported.

* Contributed code:

 - New examples: cmdline/ls.lsp, ffi/uffi.lsp
