MTP: CPU usage high while under MTP mode.
poll timeout not setting well in MTP ffs handler.
This will cause MTP ffs handler not going into sleep mode.
Bug: 121171744
Test: MTP 500 Mbyte file copy throughput from / to Host (no drop)

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.

This allows flame to boot TWRP. Still will need to work on
super partition for vendor and system access.
The plan will be to cherry-pick any updates to android-9.0
through gerrit.twrp.me to this branch as a WIP.
/dev/mtp_usb was opened before instancing MtpDevHandle, the existing fd
should be passed in otherwise MtpDevHandle::start would be blocked as it
attempted to open the device twice.

This update splits old MTP code and new MTP code from Google
into two trees, legacy and ffs. Depending on the SDK level,
the build system will select the correct version. The reason
for separating the versions out are due to older android trees
not supporting the updated MTP code from Google.
Most MTP code is from Google, with additions needed from
implementing the Java functions in C++ for TWRP and FFS.
We assume if you are in android-9.0 or above, your kernel
has support for FFS over MTP. Verify that your init.rc
is mounting the MTP FFS driver to the proper location.
