[libvirt] [PATCH 1/2] selinux: load and free selinux active file contexts configuration database

[Guannan Ren]

If we use matchpathcon() to look up selinux context for specific pathname,
it'd better actively load file contexts database by matchpathcon_init()
and free memory when finished using matchpathcon by matchpathcon_fini().
