529001f067 Switch back to StaticRotationList from DynamicRotationList
Ic005b94379f9d847ea, which introduced DynamicRotationList for
smarter input method rotation, is suspected to be causing a
strange behavior that InputMethodManager#switchToNextInputMethod
is choosing unexected/disabled IME/subtype.

With this CL, we switch back to StaticRotationList until the root
cause is addressed.

a9bda77427 Implement dynamic IME rotation based on user action
With this CL, the IME rotation order will be updated dynamically
based on user actions on IMEs. Currently only onCommitText is
took into considered.

Imagine that we have the following rotation order.
  [A, B, C, D, E]
If a user action for C is observed, the rotation order will be
updated as follows:
  [C, A, B, D, E]
Then another user action for D updates the rotation order as
follows:
  [D, C, A, B, E]

9b29d04565 Consolidate the language-switching logic
This CL does not change the existing behavior.
In I84291fd4a7d6192b, the IME rotation group is logically
devided into two groups, one is for IMEs that are declared as
supportsSwitchingToNextInputMethod == true, and the other is
IMEs that are not declared so. The problem is that the logic
was implemented with a single ime/subtype list where these two
kinds of IMEs are completely mixed. This makes the code
unnecessarily complex.
With this CL, these two rotation groups are actually managed
as two different collections separately. This allows us to
simplify the rotation logic as well as its test cases.
This CL is also a groundwork to implement smarter
language-switching logic that is applied to
language-switching-aware IMEs only.

5a647b69be Remove unnecessary internal lock
Previously, InputMethodSubtypeSwitchingController has relied on
its own internal lock for #getNextInputMethod and
class has to be invalidated whenever
InputMethodManagerService#mMethodMap is updated, any method of
InputMethodSubtypeSwitchingController should be called under
the global lock of InputMethodManagerService#mMethodMap.

As a consequence, we can conclude that
InputMethodSubtypeSwitchingController does not need its own
internal lock.

This CL also adds additional synchronization blocks into
the constructor of InputMethodManagerService to address the
existing inconsistency that methods with *Locked suffix are
called without the lock actually.

Smarter language switching will be coverted by subsequent CLs.

419b1b0498 Make a copy of Matrix in CursorAnchorInfoBuilder
This CL fixes a bug that CursorAnchorInfoBuilder does't make a
copy if the Matrix specified with #setMatrix.

Without this fix, IMM#updateCursorAnchorInfo could fail to detect
duplicated events when the same instances of
CursorAnchorInfoBuilder and Matrix are reused to optimize
performance.

81f4cb3f85 Enable CursorAnchorInfo to contain composing string
This CL adds one more functionality to CursorAnchorInfo
that enables applications to associate the composition
string with its positional information. This is useful
for an IME to handle CursorAnchorInfo asynchronously.

This is also useful for the framework to detect if
the application is unnecessarily calling
IMM#updateCursorAnchroInfo with duplicate event.

a1223cfe6f Take supportsSwitchingToNextInputMethod into considertaion
With this CL, InputMethodManager#switchToNextInputMethod starts
behaving as if there are two rotation groups: one is for the new
input methods that are declared with
supportsSwitchingToNextInputMethod set to true to indicate they
have some language switching UI, and the other is for the other
input methods to preserve the existing behavior.

In addition to the above change, this CL also fixes the behavior
of InputMethodManager#shouldOfferSwitchingToNextInputMethod()
so as to return true if and only if the former rotation group
consists of two or more input methods, as originally designed.

d1da115298 Add unit tests for InputMethodSubtypeSwitchingController
This CL adds unit tests for InputMethodSubtypeSwitchingController
as a ground work to make it aware of
supportsSwitchingToNextInputMethod in a subsequent CL.

f06569561f Introduce InputMethodSubtypeArray for memory efficient IPCs
This CL introduces InputMethodSubtypeArray which compresses
multiple instances of InputMethodSubtype to reduce the risk
of TransactionTooLargeException during IPCs.

There are some IMEs which rapidly adding new subtypes into
their supported language list. One problem here is that each
instance of InputMethodInfo internally owns the list of
supported subtypes. Basically it requires additional
200 ~ 300 bytes for each subtype when InputMethodInfo is
transffered via IPCs. We should keep the size less than
100 KB in typical scenario.

With this CL, the list of InputMethodSubtype is marshalled
with GZIP compression. Approximately one InputMethodInfo is
marshalled within 10 KB even when it has 100 subtypes.

No negative performance impact is observed so far. The cost of
decompression seems to be compensated by another optimization
in this CL. Actually marshalling cost is reduced with this CL
by caching the compressed data on demand.

c18cd393f6 Make sure InputMethodInfo implements Parcelable transitively
This CL adds one more test to make sure InputMethodInfo
implements Parcelable correctly. This test makes sure that
one can marshall and unmarshall again from an unmarshalled
copy of InputMethodInfo.
