Ability to read all of proc was placed in domain_deprecated with the
intention of reducing information leaking from proc.  Many processes try
to read proc dirs, though.  Allow this with the belief that information
leakage is from the proc files themselves rather than dir structure.

Address the following denial:
avc: denied { read } for name="/" dev="proc" ino=1 scontext=u:r:untrusted_app:s0:c512,c768 tcontext=u:object_r:proc:s0 tclass=dir permissive=0

Modify many "neverallow domain" rules to be "neverallow *" rules
instead. This will catch more SELinux policy bugs where a label
is assigned an irrelevant rule, as well as catch situations where
a domain attribute is not assigned to a process.

Since linux 3.18, commit 68c4a4f8abc60c9440ede9cd123d48b78325f7a3 has
been integrated and requires syslog_read capability a process accessing

sepolicy must be adapted to this new requirement.
