From 8cf5c8f60f51049278b08ae4cbc31df397b651fd Mon Sep 17 00:00:00 2001 From: Tianjie Xu Date: Thu, 8 Sep 2016 20:10:11 -0700 Subject: Replace minzip with libziparchive Clean up the duplicated codes that handle the zip files in bootable/recovery; and rename the library of the remaining utility functions to libotautil. Test: Update package installed successfully on angler.
