Additional filesystem functions

[GoogleCodeExporter]

The attached patch adds some filesystem functions:

  file-regular?
  file-directory?
  file-symbolic-link?
  file-size-in-bytes
  file-readable?
  file-writable?
  file-executable?
  create-symbolic-link
  create-hard-link

I have only tested it under GNU/Linux (Debian sid x86-64), and Windows
equivalents (if possible -- there are no hardlinks on Windows, AFAIK) will
need to be written.

In order to avoid bootstrapping problems, the first patch must be applied,
the a complete rebuild done (make && make -C heap && make), then the second
("activate") patch applied, and a second rebuild done (to state what's
surely obvious to the developers :-)).
