users_extra is needed by genhomedircon and when listing seusers, so it
must be kept in the policy store. Also move the FC_TMPL unlink() closer
to where the FC_TMPL is created; not a functional change, but eaiser to
follow.

We don't currently store homedir_template in the policy store, which
means genhomedircon only has a template file to use if the
homedir_template was generated from the file contexts in the same
transaction. But homedir_template isn't always generated, as in the
case with setsebool -P. In this and other cases, genhomedircon will not
have a template file resulting in an empty file_contexts.homedir file.
This commit changes this so that homedir_template is always stored in
the policy store so it can be used by genhomedircon regardless of how
policy was built. Also add the homedir_template file to the migration
script.

This patch writes file_contexts and seusers to the policy store as well as
/etc/selinux/. Additionally, file_contexts and seusers are now parsed from the
store rather than the final directory which was the old behavior. This allows
all policy related files to be kept in the policy store.

This patch writes policy.kern and file_contexts.local to the policy store as
well as /etc/selinux/. Additionally, policy.kern and file_contexts.local
are now parsed from the store rather than the final directory which was
the old behavior. This allows all policy related files to be kept in the
policy store.
This patch also renames /var/lib/selinux/tmp to 'final' and changes
policy.kern in the store to longer be a symlink.

The modules from the old store were previously copied to the new one
using setfscreatecon and shutil.copy2(). Now that refpolicy has rules
about the new policy location[1], copying the contexts is redundant.
More importantly, the setcreatefscon caused a constraint violation[2]
which made the migration fail. In python3, shutil.copy2() copies xattrs
as well which again causes problems. shutil.copy() is enough for our
needs here as it will copy the file and permissions in both py2 and 3.
We do not need the extra things that copy2() does (mtime, xattr, etc).

Changes from v1:
- Changed some methods to not take a src param anymore.
All files in /var/lib/selinux/ are now labeled the same as those in
/etc/selinux/<store>/modules/active, which in refpolicy is semanage_store_t.

Mainly used the 2to3 conversion tool. Also added in a __future__
import so that the script continues to work on Python 2.
Tested on 2.7, 3.3, 3.4. Should work on 2.6 too but untested.

We created a migration script to ease the burden of transition from the
old libsemanage store layout to the new. The script will detect all the
stores in /etc/selinux using the old layout and convert them to the new
layout in /var/lib/selinux. It also allows you to specify the default
priority to use with -p and store to operate on with -s. After migration
the script by default will leave the old store unchanged, but can be
told to remove the old modules directory with -c. Reloading policy post
migration can be disabled with the -n option.
Examples:
semanage_migrate_store
Migrating from /etc/selinux/targeted/modules/active to /var/lib/selinux/targeted/active
Attempting to rebuild policy from /var/lib/selinux
semanage_migrate_store -s targeted
Migrating from /etc/selinux/targeted/modules/active to /var/lib/selinux/targeted/active
Attempting to rebuild policy from /var/lib/selinux
semanage_migrate_store -p 150
Migrating from /etc/selinux/targeted/modules/active to /var/lib/selinux/targeted/active
