bigbiff 1f9e4847ce twrpinstall: create library for twrpinstall 
This library will need to mirror AOSP for any changes to installing
packages. The library has been separated out in order to make importing
updates from AOSP into the TWRP project.

twinstall.cpp has been removed from the recovery binary and added to
this library. It has been refactored for libziparchive.

Sideload has been reworked to use the newer methods from AOSP on
flashing packages through adb sideload.

We are also removing old libraries for adb and verifier.

Lastly before flashing a zip or image, we want to unlock block devices
for writing so that when an OTA is flashed to the inactive slot,
the flash will succeed.
