Fixes b/37629504 by not creating attachments from file URIs shared via
intent. Sharing file URIs is disallowed by Android N and later and is no
longer supported for this app.
Test: manual using the Debug command added in this change

* A security researcher crafted a gif that would cause the Android
Bitmap code to throw an NPE. That would cause messaging to crash when
decoding the NPE. Catch the NPE.
Test: manually tested the "crash.gif" attached to the bug. Stepped
through the debugger to verify we're catching the NPE and logging
the attempt. Verified normal gifs still work.

in colorMap->Colors[colorIndex]
* No range checking was done on a color index. Add range
checking and bail if the color index is out of range.
Test: tested sending a large gif that would invoke the GifTranscoder library
to make the gif smaller.

attach private files from "/data/data/com.android.messaging/"
directory to the messaging app.
* This is a manual merge from ag/871758 -- backporting a security fix from
Bugle to Kazoo.
* Don't export the MediaScratchFileProvider or the MmsFileProvider. This
will block external access from third party apps. In addition, make both
providers more robust in handling path names. Make sure the file paths
handled in the providers point to the expected directory.

* Check to make sure the returned uri from the gallery picker does
not point to bugle's data directory (or any subdir).
* Test:
Manual-
* I created the test app in the bug, the one that injects the bad
uri into Bugle. I verified the bad behavior before the fix and the
good behavior after.
* I tested the gallery to make sure picking photos,
from the photos app and drive, still work.
* I verified the behavior in the debugger to be sure the code is
catching the bad uri from the test app.

For platforms with insecure handling of media files, media files should
be opened only after the user chooses to play the media.
