file-readable? and friends should raise &i/o-file-does-not-exist

[hyln9]

The current behavior:

Ikarus Scheme version 0.0.4-rc1+, 64-bit (revision 1829, build 2009-07-28) Copyright (c) 2006-2009 Abdulaziz Ghuloum

(file-readable? "/not/there") Exception trapped by debugger. Condition components:

1. &error
2. &who: file-readable?
3. &message: "ENOENT: No such file or directory"
4. &i/o-filename: "/not/there"

I think it would be better to raise &i/o-file-does-not-exist-error', instead of its supertype&i/o-filename', as it would convey more (machine-understandable) information to the caller.

The attached patch should fix this for all procedures from ikarus.posix.ss.
