docs: update docs for the multiprocess attribute in provider element

</p></dd>

<dt><a name="multi"></a>{@code android:multiprocess}</dt>

<dd>Whether or not an instance of the content provider can be created in

every client process — "{@code true}" if instances can run in multiple

processes, and "{@code false}" if not.  The default value is "{@code false}".

<p>

Normally, a content provider is instantiated in the process of the

application that defined it.  However, if this flag is set to "{@code true}",

the system can create an instance in every process where there's a client

that wants to interact with it, thus avoiding the overhead of interprocess

communication.

</p></dd>

<dd>If the app runs in multiple processes, this attribute determines whether

multiple instances of the content provder are created. If <code>true</code>,

each of the app's processes has its own content provider object. If

<code>false</code>, the app's processes share only one content provider object.

The default value is <code>false</code>.

<p>Setting this flag to <code>true</code> may improve performance by reducing

the overhead of interprocess communication, but it also increases the memory

footprint of each process.</p></dd>
