Remove /data/dalvik-cache/profiles from domain. Profiling information
leaks data about how people interact with apps, so we don't want
the data to be available in all SELinux domains.
Add read/write capabilities back to app domains, since apps need to
read/write profiling data.
Remove restorecon specific rules. The directory is now created by
init, not installd, so installd doesn't need to set the label.

Add a service_mananger class with the verb add.
Add a type that groups the services for each of the
processes that is allowed to start services in service.te
and an attribute for all services controlled by the service
manager. Add the service_contexts file which maps service
name to target label.

read is definitely needed. Not sure about write, but adding it just
in case.

Addresses denials such as:
avc: denied { read write } for comm="dnsmasq" path="socket:[1054090]" dev="sockfs" ino=1054090 scontext=u:r:dnsmasq:s0 tcontext=u:r:netd:s0 tclass=udp_socket
This may not be needed (need to check netd to see if it should be closing
all of these sockets before exec'ing other programs), but should be harmless.

Originally we used the shell domain for ADB shell only and
the init_shell domain for the console service, both transitioned
via automatic domain transitions on sh. So they originally
shared a common set of rules. Then init_shell started to be used
for sh commands invoked by init.<board>.rc files, and we switched
the console service to just use the shell domain via seclabel entry
in init.rc. Even most of the sh command instances in init.<board>.rc
files have been converted to use explicit seclabel options with
more specific domains (one lingering use is touch_fw_update service
in init.grouper.rc). The primary purpose of init_shell at this point
is just to shed certain permissions from the init domain when init invokes
a shell command. And init_shell and shell are quite different in
their permission requirements since the former is used now for
uid-0 processes spawned by init whereas the latter is used for
uid-shell processes spawned by adb or init.
Given these differences, drop the shelldomain attribute and take those
rules directly into shell.te. init_shell was an unconfined_domain(),
so it loses nothing from this change. Also switch init_shell to
permissive_or_unconfined() so that we can see its actual denials
in the future in userdebug/eng builds.

Right now usbfs doesn't have any labels, generating the
following kernel warnings:
