show SELECT ALL icon with text in landscape mode

Though set config_allowActionMenuItemTextWithIcon as true,
icon for the "SELECT ALL" menu on ActionBar is not shown as staring
in landscape mode.
To fix it, use "SELECT ALL" icon in onCreateActionMode() to show the
icon and text together.

To show or hide text is decided by updateTextButtonVisibility() of
core/java/com/android/internal/view/menu/ActionMenuItemView.java

STEPS TO REPRODUCE: (please be specific)
1. launch Browser/Chrome and go to google.com
2. rotate to landscape mode
3. long press on URL address

Fix regression in ListView click handling

Regression caused by patch a607223f34

If an item click handler results in the ListView becoming detached
from the window, the performClick runnable could be executed twice.
Null out the mTouchModeReset runnable before running the click handler
so that it is not run by the detach handler.
