This CLs adds SElinux policies necessary to compile secondary dex files.

When an app loads secondary dex files via the base class loader the
files will get reported to PM. During maintance mode PM will compile the
secondary dex files which were used via the standard installd model
(fork, exec, change uid and lower capabilities).

What is needed:
dexoptanalyzer - needs to read the dex file and the boot image in order
to decide if we need to actually comppile.
dex2oat - needs to be able to create *.oat files next to the secondary
dex files.

Test: devices boots
      compilation of secondary dex files works without selinux denials
      cmd package compile --secondary-dex -f -m speed

In my commit f41d89eb I forgot to
switch rild and gatekeeperd rules from explicitly associating these
domains with the hal_telephony and hal_gatekeeper to using the
hal_impl_domain macro. As a result, the recent commit
a2519226 inadvertently revoked
HwBinder access from rild and gatekeeperd.

This commit fixes the issue by switching rild and gatekeeperd to the
hal_impl_domain macro.

Test: "sepolicy-analyze out/target/product/bullhead/root/sepolicy attribute haldomain"
      now lists rild and gatekeeperd
Test: "sepolicy-analyze out/target/product/bullhead/root/sepolicy attribute hal_telephony"
      still lists rild
Test: "sepolicy-analyze out/target/product/bullhead/root/sepolicy attribute hal_gatekeeper"

wificond_service is not a system_server service, so drop the
typeattribute.

Provide find permission for system_server so it can still call
wificond.

Test: compile and run on emulator. Also check built policy to verify
the permissions changes are as expected. system_server should have lost
the add permissions on wificond_service. Most importantly this needs
to be tested on a device with wificond.

This fixes the following issues introduced in commit
d225b697:
* plat_file_contexts was empty because the target was referencing
  system/sepolicy/private/file_contexts via a misspelled variable
  name.
* plat_file_contexts wasn't marked as dirty and thus wasn't rebuilt
  when system/sepolicy/private/file_contexts changed. This is because
  the file_contexts dependency was referenced via a misspelled
  variable name.
* plat_file_contexts wasn't sorted (as opposed to other similar
  targets, such as nonplat_file_contexts and file_contexts.bin). This
  may lead to unnecessary non-determinism.
* nonplat_file_contexts wasn't marked dirty and thus wasn't rebuilt
  when device-specific file_contexts file(s) changed. This is because
  the file_contexts files were referenced via a misspelled variable
  name.

Test: "make plat_file_contexts" produces a non-empty file containing
      mappings from system/sepolicy/private/file_contexts
Test: "make plat_file_contexts" updates output when
      system/sepolicy/private/file_contexts changes
Test: "make plat_file_contexts" produces output which is sorted
      accroding to rules in fc_sort

Ephemeral apps cannot open files from external storage, but can be given
access to files via the file picker.

Test: ACTION_OPEN_DOCUMENTS from an ephemeral app returns a readable fd.
Change-Id: Ie21b64a9633eff258be254b9cd86f282db1509e8

Ephemeral apps are still apps with very similar capabilities, it makes
more sense to have them under appdomain and benefit from the shared
state (and all the neverallow rules) than to try and dupplicate them and
keep them in sync.

This is an initial move, there are parts of ephemeral_app that still
need to be locked down further and some parts of appdomain that should
be pushed down into the various app domains.

Test: Builds, ephemeral apps work without denials.

After checking the auditallow logs for the rule being monitored, it's
clear that the rule is not in use and can be removed. All unused rules
should be removed, as they present needless additional attack vectors.

Test: The device boots.
Change-Id: Ie9e060c4d134212e01309a536ac052851e408320

There were some auditallow rules left around in rild.te that had logs
showing nothing was triggering them. Thus the rules they were auditing
could be removed, as that's clear indication there's no use for them.
Having rules around that aren't being used does nothing except increase
attack surface and bloat sepolicy, and so should always be removed if
possible.

Revise policy, to allow init and system_server to configure,
clear, and read kernel trace events. This will enable us to
debug certain WiFi failures.

Note that system_server is restricted to only accessing
a wifi-specific trace instance. (Hence, system_server is
not allowed to interfere with atrace.) Moreover, even for
the wifi trace instance, system_server is granted limited
permissions. (system_server can not, e.g., change which
events are traced.)

Note also that init and system_server are only granted these
powers on userdebug or eng builds.

The init.te and system_server.te changes resolve the
following denials:
