Browse mode for DocumentsUI, removed volume state.
The existing management mode is too specific, and requires that
storage backends add queryChildDocumentsForManage(), etc. Instead,
to offer more natural browsing support, add a new BROWSE_ROOT intent.
It behaves mostly like MANAGE_ROOT, except that it doesn't mutate
its Uris with setManageMode(), and it shortcuts straight to VIEW on
clicked documents.
It can be launched like this:
$ adb shell am start -a android.provider.action.BROWSE_ROOT
-d content://com.android.externalstorage.documents/root/8405-1DFB
-c android.intent.category.DEFAULT
Also rename a MetricsConstants to make it clearer, and don't
auto-mount all emulated volumes.
Fix bugs around parceling of DiskInfo/VolumeInfo. Method to resolve
the best description for a VolumeInfo, which might need to fall
back to DiskInfo.
Add back "removed" volume state so we send broadcast when a volume
is destroyed, matching the expected public API behavior.
