This class provides an API for an application to know when it is time to
destroy its EGL context when memory is being trimmed. By having this in
the framework, we can still detect whether it will be useful to destroy
any EGL contexts (because we know if doing so will destroy all of them).

Updated WebView documentation to clarify this behavior.
Additionally, if target-densityDpi is specified in the meta viewport
tag, update the display density in ZoomManager.

Bugs 5599728 and 5319237.
mInputContentType should be set for a "modern" cupcake
environment says a comment in TextView.
However, it is possible to call onEditorAction on a
TextView that didn't use any of the method that lazily
create that field. This is for instance achieved using
the extracted mode in landscape (Done, Next actions)
or in Contacts, that feature a Next/Done button in the
IME.
As a result, the action is ignored.
The patch is to force the creation of the mInputContentType
when the EditText is associated to the IME.

Stop using system properties to publish information about
the key character map path. Instead, we can retrieve it
on demand by asking the window manager.
It was possible to exhaust the supply of system properties
when repeatedly adding and removing input devices.

This change fixes race conditions that occur very regularly when
content providers are accessed from multiple threads at the same
time.
When a content provider is not already in the application's cache,
the application needs to ask the ActivityManager to obtain it.
Meanwhile, another thread can come along and do the same thing.
This can cause problems because the application attempts to
install two copies of the provider and the reference counts
and other bookkeeping can get muddled.
Similarly, there are races between releasing the last reference
to a content provider and acquiring the content provider. It's
possible for one thread to snatch the content provider from the
jaws of death. We need to handle this explicitly to ensure that
the content provider does not accidentally get released right
after it was acquired by the other thread.
This change ensures that the reference count bookkeeping and
provider map are maintained in parallel while holding the same lock.
Previously because the lock was dropped and reacquired in the
middle of acquisition and removal, it was possible for a
content provider with a zero reference count to be returned
to the application. Likewise, it was possible for a content
provider with a non-zero reference count to be disposed!
This change also performs compensatory actions when races are
detected to ensure that the necessary invariants are maintained
throughout. In particular, it ensures that the application
drops a duplicate reference to a content provider when no
longer needed.
Another way to solve this problem would be to explicitly prevent
the races from happening in the first place by maintaining a
table of content providers that are in the process of being
acquired. The first thread to attempt to acquire the provider
would store a record. The next thread would find the record
and block until the first thread was finished. I chose not
to implement the code in that manner because we would still
have needed to perform compensatory actions in the case where
the same provider binder has multiple logical names. Also,
it could cause deadlocks if the attempt to acquire
a content provider were re-entrant for some bizarre reason.

Traceview showed approximately 10% of total parse time inside the
synthetic 'trampoline' methods generated to provide inner classes
with access to their outer class's private fields. The bottleneck
in this particular case is in XmlBlock and its inner class Parser.
Making the bottlneck outer-class members and methods package-scope
instead of private removes that 10% overhead being spent within
these access trampolines.
Traceview tends to overemphasize the significance of very small
methods such as these trampolines. That said, the measured speed
gain on the ParseLargeXmlResFg op due to this patch is between
5% and 6%.
