Ensure StandaloneActivity has toolbar management consistent w/ DocumentsActivity.
Introduce a separate SearchManager class since there seemed to be a sufficient body of logic and state to warrant the separation.

Cleans up API so it consistently refers to opening or working with a
subtree of documents. Also separates isChildDocument() support from
the concept of directory tree selection.

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.
