[Rpm-maint] [PATCH 15/18] Remember that a package was installed with --nopolicy

[Steve Lawrence]

Policy modules should be ignored during policy conflict detection if a
package was installed with --nopolicy. This patch remembers if a package
was installed with --nopolicy by added a new tag, RPMTAG_NOPOLICIES,
and setting its value to the time the package was installed. When doing
conflict checks, the existence of the tag in a header tells rpm to ignore
its policies during conflict detection.
