This is a preparation to deprecate the following two methods.
* InputMethodManager#getInstance()
* InputMethodManager#peekInstance()
Since we soon need to stop relying on the current per-process
InputMethodManager singleton model to fully support multi-display,
those two methods really need to be deprecated.
With this CL, framework code no longer depends on
InputMethodManager#peekInstance(), which is also marked as deprecated
in this CL.
InputMethodManager#getInstance() is a bit tricky because it also works
as a constructor of such a per-process singleton instance. Remaining
two call-sites of this method will be migrated in a subsequent CL.
This is a mechanical refactoring, which in theory should have no
observable logical behavior difference.
There could be a small performance regression, but it is basically not
avoidable to correctly support multi-display scenarios.

Set maxTargetSdk=P so that any apps using them are required to migrate off

The crash was introduced by Ib66ef392c19c937718e7101f6d48fac3abe51ad0
The root cause of the crashing is requesting out-of-line access for the
horizontal width. This invalid access is silently ignored by
TextLine#measure() method but new implementation end up with out of
bounds access.
To makes behavior as old implementation, calling getHorizontal instead
of accessing measured result array.

Another CL in this topic changes the behavior of String.split() and
Pattern.split() to omit a "" generated by a leading zero-width match.
TextUtils.split() is implemented on top of these methods and therefore
adopts the behavior change by default.
The behavior change only affects apps targeting API versions > 28.

Layout#getOffsetForHorizontal was running in O(n^2) time, where n is the
length of the current line. The method is used when a touch event
happens on a text line, to compute the cursor offset (and the character)
where it happened. Although this is not an issue in common usecases,
where the number of characters on a line is relatively small, this can
be very inefficient as a consequence of Unicode containing 0-width
(invisible) characters. Specifically, there are characters defining the
text direction (LTR or RTL), which cause our algorithm to touch the
worst case quadratic runtime. For example, a person is able to send a
message containing a few visible characters, and also a lot of these
direction changing invisible ones. When the receiver touches the message
(causing the Layout#getOffsetForHorizontal method to be called), the
receiver's application would become not responsive.
This CL optimizes the method to run in O(n) worst case. This is achieved
by computing the measurements of all line prefixes at first, which can
be done in a single pass. Then, all the prefix measurement queries will
be answered in O(1), rather than O(n) as it was happening before.

When a sequence of characters belonging to a text is ellipsized, we
usually replace the first characters with ... and then all the others
with a 0 width character, knowing that they will be drawn, but will be
invisible. However, these positions could have had ReplacementSpans
attached to them, such as EmojiTypefaceSpan when the EmojiCompat library
is used. When this happened, all the ellipsized out characters were
invisible, apart from emojis, which were still drawn as usual (as they
were replacing sequences of 0 width characters).
This CL fixes this behaviour, by skipping those ReplacementSpans that
were completely included in ellipsis. Please check the bug for a more
detailed explanation.
