Sending a quick SMS reply to an incoming phone call was failing
with a SecurityException due to new AppOps code. The root cause
was the insert() call in SmsProvider was calling back into itself
using the UID of the caller (com.android.mms) but the package name
for the callee (com.android.phone).

Wrapped the insert() method of SmsProvider with a helper function
to save the Binder identity and restore it on completion. This
allows the quick response to make its own provider queries using
its own UID as well as package name. Read/write security checks
will be performed by the content provider framework based on the
manifest file, before insert() is called.
