Fixed SELinux denials when trying to render the camera preview
to a texture in an internal test app. See the bug for additional
information.
Bug: 183749637
Test: Ran the internal test app, doesn't crash anymore.

Only allow apps targetting < Q and ephemeral apps to open /dev/ashmem.
Ephemeral apps are not distinguishable based on target API. So allow
ephemeral_app to open /dev/ashmem for compatibility reasons.
For sake of simplicity, allow all domains /dev/ashmem permissions other
than "open". Reason being that once we can remove "open" access
everywhere, we can remove the device altogether along with other
permission.
Bug: 134434505
Test: boot crosshatch; browse internet, take picture;
no ashmem_device denials

We are only interested in removing "open" access from apps, so leave
apps with (rw_file_perms - open) permissions to /dev/ashmem
Bug: 126627315
Test: emulator boots without denials to /dev/ashmem
Change-Id: I7f03fad5e4e82aebd1b6272e4956b16f86043637
Apps are no longer allowed open access to /dev/ashmem, unless they
target API level < Q.
Bug: 113362644
Test: device boots, Chrome, instant apps work

When extraction exif info, certain file formats may requires
parsing the container. Allow mediaprovider to use extractor
to do the parsing.
bug: 73978990
Test: manually test the scenario in b/73978990 and verify
the Exif is extracted correctly.

This CL lists all the exported platform properties in
private/exported_property_contexts.
Additionally accessing core_property_type from vendor components is
restricted.
Instead public_readable_property_type is used to allow vendor components
to read exported platform properties, and accessibility from
vendor_init is also specified explicitly.
Note that whitelisting would be applied only if
PRODUCT_COMPATIBLE_PROPERTY is set on.
Bug: 38146102
Test: tested on walleye with PRODUCT_COMPATIBLE_PROPERTY=true

Vendor apps may only use servicemanager provided services
marked as app_api_service. surfaceflinger_service should be
available to vendor apps, so add this attribute and clean up
duplicate grants.

MediaProvider requires permissions that diverge from those
of a typical priv_app. This create a new domain and removes
Mtp related permissions from priv_app.
Bug: 33574909
Test: Connect with MTP, download apps and files, select ringtones
Test: DownloadProvider instrument tests, CtsProviderTestCases

The new domain wasn't fully tested, and it caused many regressions
on the daily build. Revert back to using "priv_app" domain until we
can fully test and re-land the new domain.
Temporarily add the USB functionfs capabilities to priv_app domain
to keep remainder of MtpService changes working; 33574909 is tracking
removing that from the priv_app domain.
Test: builds, boots, verified UI and downloads

Also move necessary priv_app permissions into MediaProvider domain and
remove MediaProvider specific permissions from priv_app.
The new MtpServer permissions fix the following denials:
