Module Name:
userloop.c
Abstract:
This module implements a user loop that performs two fundamental operations:
1. Queue up instructions for user shell folder migration
2. Queue up instructions for registry migration
The user loop also calls SysMig_MigrateUser, so special per-user code can be
added easily.
Author:
Calin Negreanu (calinn) 15-Aug-1998 (complete redesign)
Revision History:
Ovidiu Temereanca (ovidiut) 18-May-1999 (support for shell folders as migration dirs)

Routine Description:
pResolveSourceCollisions walks the list of shell folders and redirects

folder matches another, and one of the paths is status "merged," then the
other should be the same. By definition, given one source path, we cannot
have a merge to two separate locations.

After resolving collisions, this function scans the SFs again, eliminating
common folders that are redirected to per-user locations, if that per-user
location is in its default location.
