increased time limit for bilateral filter performance tests
Eliminated unsequenced assignments to temp3 from dpstereo.cpp.

They're unsequenced if CV_IMIN3 or CV_IMAX3 are invoked more than once
in a single expression.
MediaRecorder hint enabled for all Android devices with API level 14 and above.

It increases performance on some devices like Nexus4.
Target Android SDK version increased up to 14.
