From: Mark Hatle <mark.ha...@windriver.com>
Ensure that alternatives end up in per file provides, associated with the
source of the alternative.
Add a way to specify MANUAL_ALTERNATIVE_LINKS in order for programs that
manage their own alternatives to be more easily added to the per file
provides.
Add a function, package_do_filedeps_append to handle the setup of these
automatic per file dependencies. The method is based on the code in the
busybox package that does similar work. It replaces the brute force RPM
method that just adds a "Provides:" for each alternative. This version
of the code was written by Richard Purdie and modified by me.
Add a check before moving the item to see if the destination already exists,
if it does, assume the package already performed the rename. This is
necessary to deal with some packages that have symlinks pointing to renamed
items.
