[libvirt] [PATCH 12/15] maint: avoid 'const fooPtr' in security

[Eric Blake]

'const fooPtr' is the same as 'foo * const' (the pointer won't
change, but it's contents can).  But in general, if an interface
is trying to be const-correct, it should be using 'const foo *'
(the pointer is to data that can't be changed).

Fix up offenders in src/security.

* src/security/security_apparmor.c (reload_profile)
(AppArmorSetSecurityHostdevLabelHelper)
(AppArmorReleaseSecurityLabel, AppArmorRestoreSecurityAllLabel)
(AppArmorSetSecurityProcessLabel)
(AppArmorSetSecurityChildProcessLabel)
(AppArmorSetSecurityImageLabel, AppArmorSecurityVerify)
(AppArmorSetSecurityHostdevLabel)
(AppArmorRestoreSecurityHostdevLabel, AppArmorSetFDLabel): Drop
needless const.
* src/security/security_selinux.c
(virSecuritySELinuxSetSecurityFileLabel): Likewise.
