Previously, we were relying on linker ordering pulling in minadbd's
copy of services_to_fd instead of libadbd's, which breaks when we
switch to dynamically linking. Separate out libadbd's services into a
separate function that's in a file that isn't built into libadbd, so
that we can provide our own here.

This CL mainly changes:
a) moving the interface in struct provider_vtab to std::function;
b) code cleanup, such as moving the declaration closer to the uses,
using explicit type conversion.

We encountered segfaults in Imgdiff host tests due to the failure to
reset states of getopt. The problem can be solved by switching to use
bionic's gtest where a new process is forked for each test.
Also modify the recovery_component_test to make sure it runs in parallel.
Changes include:
1. Merge the writes to misc partition into one single test.
2. Change the hard coded location "/cache/saved.file" into a configurable
variable.

adb_server_main in adb refers to the adb server on the host, not adbd.
Since there doesn't seem to be a good reason to reuse the declaration
from adb's headers, give minadbd a main function of its own.

These tests aren't completely representative in that they don't run in
the recovery image. We might want to look in to adding a self-test
option to the recovery UI. Until then, these can be run on a normal
device (which is easier to do anyway).

The patch "[RFC] usb: gadget: f_fs: Add flags
to descriptors block" marks the current
usb_functionfs_descs_head format deprecated
and introduces support for sending SuperSpeed
descriptors.
This CL makes adbd to send Descriptors in the
new format. Adbd would fall back to the old
format, if kernel is not able to recognize
the new format. This is done to prevent
adbd from breaking in the older versions
of the kernel.

Split the adb-specific portions (fetching a block from the adb host
and closing the connections) out from the rest of the FUSE filesystem

as well.

Implement a new method of sideloading over ADB that does not require
the entire package to be held in RAM (useful for low-RAM devices and
devices using block OTA where we'd rather have more RAM available for
binary patching).
We communicate with the host using a new adb service called
"sideload-host", which makes the host act as a server, sending us
different parts of the package file on request.
We create a FUSE filesystem that creates a virtual file
"/sideload/package.zip" that is backed by the ADB connection -- users
see a normal file, but when they read from the file we're actually
fetching the data from the adb host. This file is then passed to the
verification and installation systems like any other.
To prevent a malicious adb host implementation from serving different
data to the verification and installation phases of sideloading, the
FUSE filesystem verifies that the contents of the file don't change
between reads -- every time we fetch a block from the host we compare
its hash to the previous hash for that block (if it was read before)
and cause the read to fail if it changes.
One necessary change is that the minadbd started by recovery in
sideload mode no longer drops its root privileges (they're needed to
mount the FUSE filesystem). We rely on SELinux enforcement to
restrict the set of things that can be accessed.

Make minadbd drop its root privileges after initializing. We need to
make the /tmp directory writable by the shell group so that it can
drop the sideloaded file there.

Rather than depending on the existence of some place to store a file
that is accessible to users on an an unbootable device (eg, a physical
sdcard, external USB drive, etc.), add support for sideloading
packages sent to the device with adb.
This change adds a "minimal adbd" which supports nothing but receiving
a package over adb (with the "adb sideload" command) and storing it to
a fixed filename in the /tmp ramdisk, from where it can be verified
and sideloaded in the usual way. This should be leave available even
on locked user-build devices.
The user can select "apply package from ADB" from the recovery menu,
which starts minimal-adb mode (shutting down any real adbd that may be
running). Once minimal-adb has received a package it exits
(restarting real adbd if appropriate) and then verification and
installation of the received package proceeds.
