Subject: Change storage migration to use quota APIs.
X-Git-Tag: android-x86-9.0-r1~298^2
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=a01369893823ee3d62ea79c422a76fe810f8a5cb;p=android-x86%2Fframeworks-native.git

Change storage migration to use quota APIs.

New quota APIs are much faster than trying to measure manually, and
removing this last user of calculateDirectorySize() means we can
remove it once and for all.

Bug: 36056324
Test: builds, boots
