This enables an optimization of bypassing the FUSE overhead when
migrating emulated storage between volumes.

Users can pick files from vfat devices through the Storage Access
Framework, which are returned through ParcelFileDescriptors. Grant
apps write access to those files. (Direct access to the files on
disk is still controlled through normal filesystem permissions.)

Raw physical storage devices are mounted by vold under /mnt/media_rw
and then wrapped in a FUSE daemon that presents them under /storage.
Normal apps only have access through /storage, but platform apps
(such as ExternalStorageProvider) often bypass the FUSE daemon for
performance reasons.

The current neverallow rule (compile time assertion)
neverallow { domain -gatekeeperd -system_server } gatekeeper_service:service_manager find;
asserts that no rule is present which allows processes other than
system_server from asking servicemanager for a gatekeeperd token.
However, if system_server leaks the token to other processes, it may
be possible for those processes to access gatekeeperd directly, bypassing
servicemanager.
Add a neverallow rule to assert that no process other than system_server
are allowed to make binder calls to gatekeeperd. Even if another process
was to manage to get a binder token to gatekeeperd, it would be useless.
Remove binder_service() from gatekeeperd. The original use of the
binder_service() macro was to widely publish a binder service.
If this macro is present and the calling process has a gatekeeperd
binder token, it's implicitly possible for the following processes
to make a binder call to gatekeeperd:
* all app processes
* dumpstate
* system_server
* mediaserver
* surfaceflinger
Removing binder_service revokes this implicit access.
Add explicit access for system_server to make binder calls to
gatekeeperd.
Add explicit access for gatekeeperd to make calls to keystore.
This was implicitly granted via binder_service() before, but now
needs to be explicit.

Commit 85ce2c706e removed hard link
support from create_file_perms, but system_server requires hard
link support for split APKs. Allow it.
Addresses the following denial:

Steps to reproduce:
1) Find the directory "hellogoogle3.splitapk"
2) adb install-multiple -r hellogoogle3_incremental.apk
3) adb install-multiple -r -p com.google.android.samples.hellogoogle3 native.apk
Expected:
2nd APK installs successfully.
Actual:
2nd APK fails to install.

On debuggable builds, system_server can request app heap dumps
by running something similar to the following commands:
% adb shell am set-watch-heap com.android.systemui 1048576
% adb shell dumpsys procstats --start-testing
which will dump the app's heap to /data/system/heapdump. See
framework/base commit b9a5e4ad30c9add140fd13491419ae66e947809d.
Allow this behavior.
