Stephen Smalley 3322d0d64f selinux: keep SELinux in sync with new capability definitions
When a new capability is defined, SELinux needs to be updated.
Trigger a build error if a new capability is defined without
corresponding update to security/selinux/include/classmap.h's
COMMON_CAP2_PERMS.  This is similar to BUILD_BUG_ON() guards
in the SELinux nlmsgtab code to ensure that SELinux tracks
new netlink message types as needed.

Note that there is already a similar build guard in
security/selinux/hooks.c to detect when more than 64
capabilities are defined, since that will require adding
a third capability class to SELinux.

A nicer way to do this would be to extend scripts/selinux/genheaders
or a similar tool to auto-generate the necessary definitions and code
for SELinux capability checking from include/uapi/linux/capability.h.
AppArmor does something similar in its Makefile, although it only
needs to generate a single table of names.  That is left as future
work.
