Tell the reason why IMM called startInput().
As a preparation to fix Bug 25373872, this CL introduces an additional
int parameter into the following two methods
- IInputMethodManager.startInput()
- IInputMethodManager.windowGainedFocus()
so that IMMS can know why IMM needs to start input. Currently the
"startInputReason" parameter is used only for debug message only when
the OS is rebuilt with flipping IMMS#DEBUG to true. Basically this
should have no impact in production builds except for a tiny overhead
of having one int parameter in some internal IPC calls.
Note that since 7663d80f6b6fd6ca7a736c3802013a09c0abdeb9 [1] basically
IMMS#windowGainedFocus() has been a superset of IMMS#startInput().
Hence we should pass to "startInputReason" parameter to
IMMS#windowGainedFocus() as well as IMMS#startInput().
