An app created a SpannableStringBuilder, one of which's spans was the
instance of the string builder itself (that is, the builder contained a span
that was the builder). This caused infinite recursion in the hashcode()
method because it computes a hash from its fields, including all of its spans.
The fix detects the case where a span equals the current instance and
noops the computation on that span. A similar adjustment was made to equals()
to avoid the same recursion problem.

Fix for bug 6473708. This patch changes from "last update wins" to
merging together the change regions, in the logic of deciding which
blocks need to be updated for painting, so that when there are multiple
changes batched for a draw, they're all taken into account.

This patch fixes behavior where attempting to place the cursor at
the end of a string where the last character is a combining accent
actually placed it before that accent. This was especially annoying
for editing Thai text, because it made it difficult to delete a
trailing tone mark.
Fixes bug 8947569 "Can't place cursor after combining accent" and bug
10398332 "[Thailand] Thai Language(IME) -- Can't delete Thai tone mark
while writing message"

ActionBar uses a transition to animate text changes. This transition
depends on testing the equality of start/end text values in CharSequence
objects. Without equals(), SpannableString will return false for objects
whose references are different, but whose text is exactly the same.
This CL adds the equals() method, and the accompanying hashcode method,
to ensure that two Spanned implementations will always be equal
if their text and span data are equal.

This reverts commit 3954fd9a05, which
is equivalent to re-applying 8a1597b396.
The change ("Take the input device into account for meta state") was
valid but caused CTS test failures because the test was wrong. The
test injected a key event with the meta state missing. This faulty
test was masked by the old toggle behavior.
This reverts commit 8a1597b396. That
commit broke some of the handling of meta state, which in turn caused
CTS test failures, notably bug 10210151 (CTS:
android.text.method.cts.BaseKeyListenerTest#testBackspace_withSendKeys
is failing on KLP).
So this revert fixes those test failures, but leaves bug 8303489
(Pressing shift on the hardware keyboard messes with unrelated
keypresses, including virtual ones) still present. We'll plan to
address that in a future release.

This fixes bug 9900288: Multiple apps crashing; AIOBE at
android.text.AndroidBidi.directions.
The AndroidBidi.directions() method was not correctly handling the case
of a run of length 0, causing ArrayIndexOutOfBoundsException. This
patch simply avoids accessing the levels array in that case.

In some cases, we end up being called by code that doesn't have a valid
Context. It got away with this historically because it wasn't formatting
times (just dates), so it never went down a path that tried to query the
user's 12/24-hour preference. This patch just ensures that we don't try
to get the preference unless we actually need it.

Make sure screen layout changes are taken into account in Configuration diffs.
Initialize the SystemProperty from Global settings on startup of
ActivityManagerService.
TextUtils checks the override flag to decide if the default layout direction
should be forced to RTL.
