Detailed ContentProvider permissions checks.
The new MediaProvider design has an internal dynamic security model
based on the value stored in OWNER_PACKAGE_NAME, so the OS always
needs to consult the provider when resolving Uri permission grants.
Blocking calls from the system process like this are typically
discouraged, but this is the best we can do with the limited time
left, and there is existing precident with getType().
For now, use "forceUriPermissions" as a proxy for determining when
we need to consult the provider directly.
