Part 2 of Fixing a security hole in mount table.

["Pierre A. Humblet" <pierre at phumblet dot no-ip dot org>]

This is the follow up on yesterday's patch.
There is no change in external behavior, just cleaning up.

The main innovation is the new function cygheap_user::init
that initializes the user name and sid just after the cygheap is
initialized. 
The information can then be used in user_shared_initialize and
need not be obtained again in internal_getlogin.
