Factor out a new function from ApplyFromSdcard that installs a package
from a local path. Inside this function, we start the fuse and choose the
type of data provider depending on the path string. And similar to the
existing logic, we treat the package as a block map if the path starts
with a '@'.
This is part of the effort to install larger than 2GiB packages on ILP32
devices.
Bug: 127071893
Test: Build a 32 bit sailfish and create a 3GiB OTA package. Sideload
the package, uncrypt and install the package from sdcard.

Test: Enter rescue mode on taimen. Send the following commands:
`adb rescue getprop ro.build.fingerprint`
`adb rescue getprop ro.build.date.utc`
`adb rescue install /path/to/package.zip`
Test: Sideload on taimen w/ `adb sideload /path/to/package.zip`.

This leaves the FD implementation details to subclasses. In particular,
it allows minadbd to do additional works with the FD after sideloading.

It's no longer needed with the newly added FuseDataProvider class. Also
cleans up the parameters for run_fuse_sideload.
Bug: 127071893
Test: unit tests pass, run a sideload

The fuse data provider for adb/sdcard shares common code and structures.
This cl creates a FuseDataProvider base class and provides
implementations for adb and sdcard.
In the follow cls, we can kill the provider_vtab struct; and also add
another implementation to parse a block map file and provides data.
Test: unit tests pass, sideload a package, apply a package from sdcard

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.
Test: recovery_component_test
Test: minadbd_test
Test: Sideload a package on marlin.

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).

Split the adb-specific portions (fetching a block from the adb host
and closing the connections) out from the rest of the FUSE filesystem
code, so that we can reuse the fuse stuff for installing off sdcards
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.

Adds the following edify functions:
mount unmount format show_progress delete delete_recursive
package_extract symlink set_perm set_perm_recursive
This set is enough to extract and install the system part of a (full)
OTA package.
Adds the updater binary that extracts an edify script from the OTA
package and then executes it. Minor changes to the edify core (adds a
sleep() builtin for debugging, adds "." to the set of characters that
can appear in an unquoted string).
