424	umask support	Mario Domenech Goulart		"Chicken currently doesn't provide bindings to {{{umask}}}(2).  It would be nice to have a procedure for that.

Here's the proposed syntax and semantics:

{{{(set-file-creation-mode-mask mask)}}}

Returns the previous value of the file mode mask.

{{{mask}}} can be specified using Unit posix's {{{perm/*}}} constants.

Initial discussion on chicken-hackers proposes adding umask support to the posix unit.
