Remove O_SYNC from mzExtractRecursive() and PackageExtractFileFn(). These functions deal with extracting whole files from the update package onto a filesystem. If run on ext4 on a rotating disk, for example, the O_SYNC flag will cause serious performance problems and the extraction proecss can take over 30 minutes, with no obvious benefits. This API function already calls fsync(fd) after each file is extracted to ensure data and metadata is written to the underlying block device, so the O_SYNC calls should be superfluous and safely removable. This change does not affect the OTA patch paths or any modification of the bootloader partition or writes to other 'emmc' partitions.

The Recovery Image
Quick turn-around testing
mm -j && m ramdisk-nodeps && m recoveryimage-nodeps
# To boot into the new recovery image
# without flashing the recovery partition:
adb reboot bootloader
fastboot boot $ANDROID_PRODUCT_OUT/recovery.img
Running the tests
# After setting up environment and lunch.
mmma -j bootable/recovery
# Running the tests on device.
adb root
adb sync data
# 32-bit device
adb shell /data/nativetest/recovery_unit_test/recovery_unit_test
adb shell /data/nativetest/recovery_component_test/recovery_component_test
# Or 64-bit device
adb shell /data/nativetest64/recovery_unit_test/recovery_unit_test
adb shell /data/nativetest64/recovery_component_test/recovery_component_test
