KaiGai Kohei 44c2d9bdd7 Add audit messages on type boundary violations
The attached patch adds support to generate audit messages on two cases.

The first one is a case when a multi-thread process tries to switch its
performing security context using setcon(3), but new security context is
not bounded by the old one.

  type=SELINUX_ERR msg=audit(1245311998.599:17):        \
      op=security_bounded_transition result=denied      \
      oldcontext=system_u:system_r:httpd_t:s0           \
      newcontext=system_u:system_r:guest_webapp_t:s0

The other one is a case when security_compute_av() masked any permissions
due to the type boundary violation.

  type=SELINUX_ERR msg=audit(1245312836.035:32):	\
      op=security_compute_av reason=bounds              \
      scontext=system_u:object_r:user_webapp_t:s0       \
      tcontext=system_u:object_r:shadow_t:s0:c0         \
      tclass=file perms=getattr,open
