Stephen Smalley 45731c70ef Annotate MLS trusted subjects and objects.
When using MLS (i.e. enabling levelFrom= in seapp_contexts),
certain domains and types must be exempted from the normal
constraints defined in the mls file.  Beyond the current
set, adbd, logd, mdnsd, netd, and servicemanager need to
be able to read/write to any level in order to communicate
with apps running with any level, and the logdr and logdw
sockets need to be writable by apps running with any level.

This change has no impact unless levelFrom= is specified in
seapp_contexts, so by itself it is a no-op.
