Can not compile mediacodec for android

[chinshou]

Summary of the bug:
When I --enable-mediacodec and compile the library for android. The config.log report unknown type name 'bool'

check_lib mediandk stdint.h media/NdkMediaFormat.h AMediaFormat_new -lmediandk
check_func_headers stdint.h media/NdkMediaFormat.h AMediaFormat_new -lmediandk
test_ld cc -lmediandk

I fixed the problem by adding stdbool.h to mediandk in configure file

check_lib mediandk "stdint.h stdbool.h media/NdkMediaFormat.h" AMediaFormat_new -lmediandk

The fix has referenced the code for cameara2ndk

check_lib camera2ndk "stdbool.h stdint.h camera/NdkCameraManager.h" ACameraManager_create -lcamera2ndk
