f6158eb918 Support starting fuse from a block map
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.

311e6ca7b6 Implement FuseBlockDataProvider
Adds a fuse data provider that parses the metadata from a block map,
reads the data from the given ranges of the block device; and provides
the data to the fuse.

Test: unit tests pass, install a package from block map

2be9737cf4 Remove the FD parameter from FuseDataProvider ctor.
This leaves the FD implementation details to subclasses. In particular,
it allows minadbd to do additional works with the FD after sideloading.

5e6832a24d Remove the provider_vtab
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

ea2912f187 Create a FuseDataProvider base class
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

4b51c3ab40 Export fuse_sideload.h for libfusesideload.
Move the module into a separate directory so that we can export only the
expected header.

With this change, minadbd no longer needs to include bootable/recovery.

Test: mmma -j bootable/recovery
