Move to using Toolbar for all actions. Drawer contains its own
Toolbar with separate title, and hamburger is always visible. Change
drawer items to match spec. Switching to Toolbar allows us to remove
nasty dialog-on-tablet hacks, yay! This also means we can finally
get real IME resizing support.
Move to using elevation for all shadows; this removes more nasty
hacks around drawing directory shadows.

Introduce new ACTION_PICK_DIRECTORY that allows users to grant access
to an entire document subtree. Instead of requiring grants for each
individual document, this leverages new prefix URI permission grants
by defining new "via"-style URIs:
content://com.example/via/12/document/24/
This references document 24 by using a prefix grant given for
document 12. Internally, we use isChildDocument() to enforce that
24 is actually a descendant (child, grandchild, etc) of 12. Since
this is an optional API, providers indicate support with
Root.FLAG_SUPPORTS_DIR_SELECTION.
Extend DocumentsUI to support picking directories. Expose
createDocument() API to work with returned directories.
Offer to canonicalize via-style URIs into direct URIs, generating
exact permission grants along the way. Override openAssetFile()
to pass through CancellationSignal. Move testing code into ApiDemos.
