Fix indeterminate ProgressBars with weird sizes and padding; optimize 

ActionBar measurement

Fix a bug where preserved aspect ratios in ProgressBar indeterminate
drawables were causing drawable bounds to be calculated incorrectly
when the ProgressBar had padding specified.

Measure the ActionBar menu view's height with EXACT measure mode,
preventing an extra measure pass to match child heights for some
cases.
